[PATCH RFC 00/40] clk: port full Linux Common Clock Framework to U-Boot

[PATCH RFC 00/40] clk: port full Linux Common Clock Framework to U-Boot

[Casey Connolly]

This RFC provides a proof of concept for using the full Linux CCF in
U-Boot and consequently porting full Linux clock drivers with extremely
minimal changes.

== Overview ==

This RFC is pretty long but can be separated into a few chunks. The
first patches relate to Linux API compatibility and just contain small
self contained changes, these can go upstream regardless of CCF.

The next group of changes prepare for importing CCF from Linux, the
standalone fixed clock drivers are moved to clk/basic, the existing
U-Boot CCF drivers are moved to clk/uccf, and struct clk_ops is renamed
to clk_ops_uboot.

Additionally, clk_set_rate() is changed so that it returns a signed
long, since it can return negative values. This is also done to align
with CCF but it's a standalone improvement nonetheless.

The next changes import CCF from Linux 6.19 and then adjust it to
compile and work with U-Boot. These commits are split up mostly to
try and reduce the size. Finally clk-uclass is adjusted for CCF, this
definitely will need some additional passes to be a bit cleaner.

With CCF done, sandbox clk-ccf driver gets a CCF_FULL port, the clk_ccf
tests are adjusted to pass.

Lastly, a PoC port of Qualcomms Linux clock drivers is done, this
only has sm8650 clocks but they serve the desired purpose. The changes
necessary to the Linux drivers are mostly to deal with U-Boots driver
model, the actual platform specific clock drivers require essentially
zero changes!

=== Feedback ===

I'd like to get feedback on the overall architecture and ideas, feel
free to point out any dead code or printf's I forgot about, but I'll for
sure do a more detailed cleanup before the next revision.

I would definitely like to input on how to deal with clk-uclass, since
it's now supporting 3 different clock frameworks, but I'm now sure how
best to separate the code out without duplicating code.

In terms of overall architecture, CCF is a departure from the uclass
model that U-Boot has stuck too for so long. If this is a success then
I think it could make a lot of sense to make similar changes for power
domains and resets. I think this change offers a lot of additional
flexibility which has been sorely missed.

== Motivation ==

There were quite a few motivating factors behind this effort which I
think provide useful context for this series:

1. Existing UCLASS_CLK support in U-Boot (even with U-Boots minimal CCF)
   doesn't provide a fully cohesive API nor implement the necessary
   functionality to support complex modern platforms without a lot of
   additional effort.

2. While trying to enable display support on Qualcomm, it became clear
   that U-Boots clock framework was a severe limiting factor,
   particularly for more complicated setups like "bonded" dual-DSI.

3. The current state of Qualcomm clock drivers in U-Boot is pretty poor,
   as the old very basic driver code is being expected to support more
   and more complicated usecases. Clock support is generally the most
   complicated part of bringing up any new Qualcomm platform, so being
   able to properly reuse Linux drivers with the familiar API greatly
   reduces the amount of friction when working on U-Boot support for
   complicated peripherals like the display.

Consequently, My aim with this effort was primarily to provide API
compatibility with Linux as much as possible, minimising the changes
that have to be made to clock drivers to port them from Linux, and
reducing the chance of introducing U-Boot specific bugs.

=== clk_ops/UCLASS_CLK ===

CCF_FULL drivers should NOT use UCLASS_CLK, since CCF uses a totally
independent clock API. If the clocks are provided by another device like
a phy, they can simply be registered with the clk core the same way they
are in Linux. Standalone clock drivers should use UCLASS_NOP.

Clocks must all be registered during driver probe, the CCF will ensure
that a given clock provider is probed (via a global ofnode -> device
lookup) before checking the of_providers, thus making sure the clocks
are registered so that the consumer can use them. There is currently no
special handling for cyclical dependencies.

=== struct clk ===

It's definitely debatable if it makes sense to have 3 different structs
for each clk (clk_hw, clk_core and clk). I do think clk_hw and clk_core
are justified, since clk_hw is more tied to the hardware description and
typically nested in a clk-specific descriptor while clk_core contains
the internal runtime state of the clk which should remain private to
CCF core.

It could make sense to merge clk and clk_core, but since struct clk is
public in U-Boot, where it's an opaque pointer in Linux this would be
a substantial effort. In Linux struct clk objects are allocated inside
CCF, but in U-Boot they're allocated by the driver, this would need to
be resolved before we investigate combining these structs.

=== Memory/perf overhead ===

The memory and size overhead of CCF is undoubtably bigger than uCCF,
although I suspect the difference is less than it might seem at
first glance. In particular: clk_core is only ~50 bytes larger than
struct udevice on ARM64, and an additional 120 bytes is saved for each
U_BOOT_DRIVER used by uCCF.

On the other hand, the CPU overhead is probably more significant,
but not an unreasonable cost to ensure correctness and propagate rate
changes across the clock tree.

Just comparing the binary size of sandbox64_defconfig with uCCF vs
CCF_FULL, CCF_FULL results in a 135k size increase in the binary. I
haven't done any more detailed analysis here (still haven't got buildman
to play nice...).

=== SPL ===

This RFC doesn't have any SPL specific support, I think this role is
better fulfilled by UCLASS_CLK.

=== U-Boot's old CCF port ===

The original CCF port done for IMX platforms is vastly different in API,
scope, and function to CCF_FULL, to differentiate I refer to it
as "uCCF".

I have kept support for this in and made it mutually exclusive with
CCF_FULL. uCCF drivers have been moved to drivers/clk/uccf, with the new
CCF port in drivers/clk/ccf.

Included near the end of this series is a port of Sandbox's clk-ccf
driver from uCCF over to CCF_FULL, this might be a useful reference for
other drivers (although it's probably better to just adapt the Linux
drivers).

=== Compat shim ===

Lastly, this series includes a compat shim which allows UCLASS_CLK
drivers to somewhat work with CCF, I would imagine this being useful
if some generic peripheral device provides a clock for example, but in
almost all cases I think it's better to implement a proper CCF clock
device. Unless there is a particular usecase for this I would probably
not include it in the next revision.

== TODO/Outstanding issues ==

* Clean up clk-uclass.c, does it make sense to somewhow split it in two?
* Assess test coverage, have basic sandbox tests, would like to mostly
  use integration tests (i.e. diff the clk summary) once more platforms
  are supported.
* pre-relocation support is currently missing, on Qualcomm at least I
  would prefer to completely skip FDT scanning pre-reloc, there is a
  patch in this series which does that. It is very non-trivial to try
  and handle clocks pre-reloc.

[PATCH RFC 02/40] common: add an option to skip DM pre-relocation

[Casey Connolly]

For some platforms like Qualcomm, it isn't necessary to perform a full
DM init and scan prior to relocation, it's also particularly slow since
it runs with dcache disabled and prior to building the livetree.

The only device which needs to be probed pre-reloc is the serial
port (otherwise U-Boot will panic), however this can be found through
/chosen/stdout-path.

Therefore we can avoid scanning the entire FDT and binding devices,
instead just binding the serial port and clock driver on-demand.

This decreases the total time from power on to reaching the interactive
U-Boot shell be about 50% (from ~2.8s to 1.8s).

[PATCH RFC 04/40] qcom: rpmh: don't error for SLEEP requests

[Casey Connolly]

Just stub them out since the caller might also send active votes. Since
we don't suspend there's no risk of missing votes here, we never enter
the sleep state.

[PATCH RFC 05/40] string: add strdup_const and kstrdup_const

[Casey Connolly]

Extend Linux compat by adding kstrdup_const(), backed by lib/string.c.
This leverages U-Boots .rodata section on ARM64 to avoid pointlessly
duplicating const strings.

This is used by the Linux CCF_FULL port and may be useful elsewhere
in U-Boot.

[PATCH RFC 08/40] compat: add kref implementation

[Casey Connolly]

This is a very basic port of Linux' kref, we don't actually need atomics
so we just use a simple counter. This is used by CCF to free unused
clocks.

[PATCH RFC 11/40] devres: add devm_krealloc

[Casey Connolly]

Loosely based on the Linux version, this makes it possible to krealloc()
devm managed memory. Currently it depends on tracking the allocation
size in struct devres even when DEBUG_DEVRES is disabled, but it's a
relatively small tradeoff for the additional functionality.

I think this is not necessary. drivers/clk/imx/Makefile already requires
that imx config options be enabled for the driver to be compiled in.

Almost all of them do. I see:
$ rg obj.*CLK_CCF drivers/clk/
drivers/clk/Makefile
10:obj-$(CONFIG_$(PHASE_)CLK_CCF) += clk.o clk-divider.o clk-mux.o clk-gate.o
11:obj-$(CONFIG_$(PHASE_)CLK_CCF) += clk-fixed-factor.o
61:obj-$(CONFIG_SANDBOX_CLK_CCF) += clk_sandbox_ccf.o

drivers/clk/exynos/Makefile
10:obj-$(CONFIG_$(PHASE_)CLK_CCF)       += clk.o clk-pll.o

drivers/clk/imx/Makefile
5:obj-$(CONFIG_$(PHASE_)CLK_CCF) += clk-gate2.o clk-pllv3.o clk-pfd.o

But exynos is guarded by CONFIG_CLK_EXYNOS to start with. So I think
this is right, and also something that could just be standalone and
picked up shortly as it's a build cleanup.

[PATCH RFC 16/40] clk: move U-Boot CCF to clk/uccf

[Casey Connolly]

Prepare for the introduction of full CCF support by moving the existing
U-Boot CCF support to a uccf subdirectory.

Due to a number of incompatibilities it won't be possible to support
existing U-Boot CCF clocks with the full CCF, this allows us to support
both. While it may make sense to remove U-Boot CCF in the future, it may
be necessary to continue supporting it to meet space/memory requirements
in SPL for some platforms.

[PATCH RFC 17/40] clk: rename clk_ops to clk_ops_uboot

[Casey Connolly]

In preparation for supporting full CCF, rename U-Boot's clk_ops
to clk_ops_uboot, these ops are specific to UCLASS_CLK and are too
incompatible with full CCF.

[PATCH RFC 18/40] clk: move fixed clocks to clk/basic

[Casey Connolly]

Linux CCF has incompatible implementations of fixed-rate/fixed-factor
clocks, move the U-Boot versions of these drivers to clk/basic and only
build them if CCF_FULL is not enabled.

[PATCH RFC 19/40] clk: make clk_set_rate() return signed long

[Casey Connolly]

The docs for clk_set_rate() indicate that it can return an error and
this is desirable for clock drivers to do, the ulong return type however
implies that this can't happen.

Fix the return type and adapt all clock drivers. Consumers can now more
easily handle error conditions.

This function can return negative values, update its prototype to
reflect this and avoid potential underflow issues with error conditions.

[PATCH RFC 21/40] clk: import full CCF from Linux

[Casey Connolly]

This is a plain copy/paste with no modifications from Linux 6.19.0, it
will be adapted for U-Boot in future commits.

To continue supporting U-Boot CCF, clk-provider.h becomes a wrapper that
imports either the uccf or ccf_full variant based on the config, since
these are mutually exclusive.

+ * with 'xtal' in the 'name' member to find the clock provided by the

+ *
+ * @prepare:	Prepare the clock for enabling. This must not return until
+ *		the clock is fully prepared, and it's safe to call clk_enable.
+ *		This callback is intended to allow clock implementations to
+ *		do any initialisation that may sleep. Called with
+ *		prepare_lock held.
+ *
+ * @unprepare:	Release the clock from its prepared state. This will typically
+ *		undo any work done in the @prepare callback. Called with
+ *		prepare_lock held.
+ *
+ * @is_prepared: Queries the hardware to determine if the clock is prepared.
+ *		This function is allowed to sleep. Optional, if this op is not
+ *		set then the prepare count will be used.
+ *
+ * @unprepare_unused: Unprepare the clock atomically.  Only called from
+ *		clk_disable_unused for prepare clocks with special needs.
+ *		Called with prepare mutex held. This function may sleep.
+ *
+ * @enable:	Enable the clock atomically. This must not return until the
+ *		clock is generating a valid clock signal, usable by consumer
+ *		devices. Called with enable_lock held. This function must not
+ *		sleep.
+ *
+ * @disable:	Disable the clock atomically. Called with enable_lock held.
+ *		This function must not sleep.
+ *
+ * @is_enabled:	Queries the hardware to determine if the clock is enabled.
+ *		This function must not sleep. Optional, if this op is not
+ *		set then the enable count will be used.
+ *
+ * @disable_unused: Disable the clock atomically.  Only called from
+ *		clk_disable_unused for gate clocks with special needs.
+ *		Called with enable_lock held.  This function must not
+ *		sleep.
+ *
+ * @save_context: Save the context of the clock in prepration for poweroff.
+ *
+ * @restore_context: Restore the context of the clock after a restoration
+ *		of power.
+ *
+ * @recalc_rate: Recalculate the rate of this clock, by querying hardware. The
+ *		parent rate is an input parameter.  It is up to the caller to
+ *		ensure that the prepare_mutex is held across this call. If the
+ *		driver cannot figure out a rate for this clock, it must return
+ *		0. Returns the calculated rate. Optional, but recommended - if
+ *		this op is not set then clock rate will be initialized to 0.
+ *
+ * @round_rate:	Given a target rate as input, returns the closest rate actually
+ *		supported by the clock. The parent rate is an input/output
+ *		parameter.
+ *
+ * @determine_rate: Given a target rate as input, returns the closest rate
+ *		actually supported by the clock, and optionally the parent clock
+ *		that should be used to provide the clock rate.
+ *
+ * @set_parent:	Change the input source of this clock; for clocks with multiple
+ *		possible parents specify a new parent by passing in the index
+ *		as a u8 corresponding to the parent in either the .parent_names
+ *		or .parents arrays.  This function in affect translates an
+ *		array index into the value programmed into the hardware.
+ *		Returns 0 on success, -EERROR otherwise.
+ *
+ * @get_parent:	Queries the hardware to determine the parent of a clock.  The
+ *		return value is a u8 which specifies the index corresponding to
+ *		the parent clock.  This index can be applied to either the
+ *		.parent_names or .parents arrays.  In short, this function
+ *		translates the parent value read from hardware into an array
+ *		index.  Currently only called when the clock is initialized by
+ *		__clk_init.  This callback is mandatory for clocks with
+ *		multiple parents.  It is optional (and unnecessary) for clocks
+ *		with 0 or 1 parents.
+ *
+ * @set_rate:	Change the rate of this clock. The requested rate is specified
+ *		by the second argument, which should typically be the return
+ *		of .round_rate call.  The third argument gives the parent rate
+ *		which is likely helpful for most .set_rate implementation.
+ *		Returns 0 on success, -EERROR otherwise.
+ *
+ * @set_rate_and_parent: Change the rate and the parent of this clock. The
+ *		requested rate is specified by the second argument, which
+ *		should typically be the return of .round_rate call.  The
+ *		third argument gives the parent rate which is likely helpful
+ *		for most .set_rate_and_parent implementation. The fourth
+ *		argument gives the parent index. This callback is optional (and
+ *		unnecessary) for clocks with 0 or 1 parents as well as
+ *		for clocks that can tolerate switching the rate and the parent
+ *		separately via calls to .set_parent and .set_rate.
+ *		Returns 0 on success, -EERROR otherwise.
+ *
+ * @recalc_accuracy: Recalculate the accuracy of this clock. The clock accuracy
+ *		is expressed in ppb (parts per billion). The parent accuracy is
+ *		an input parameter.
+ *		Returns the calculated accuracy.  Optional - if	this op is not
+ *		set then clock accuracy will be initialized to parent accuracy
+ *		or 0 (perfect clock) if clock has no parent.
+ *
+ * @get_phase:	Queries the hardware to get the current phase of a clock.
+ *		Returned values are 0-359 degrees on success, negative
+ *		error codes on failure.
+ *
+ * @set_phase:	Shift the phase this clock signal in degrees specified
+ *		by the second argument. Valid values for degrees are
+ *		0-359. Return 0 on success, otherwise -EERROR.
+ *
+ * @get_duty_cycle: Queries the hardware to get the current duty cycle ratio
+ *              of a clock. Returned values denominator cannot be 0 and must be
+ *              superior or equal to the numerator.
+ *
+ * @set_duty_cycle: Apply the duty cycle ratio to this clock signal specified by
+ *              the numerator (2nd argurment) and denominator (3rd  argument).
+ *              Argument must be a valid ratio (denominator > 0
+ *              and >= numerator) Return 0 on success, otherwise -EERROR.
+ *
+ * @init:	Perform platform-specific initialization magic.
+ *		This is not used by any of the basic clock types.
+ *		This callback exist for HW which needs to perform some
+ *		initialisation magic for CCF to get an accurate view of the
+ *		clock. It may also be used dynamic resource allocation is
+ *		required. It shall not used to deal with clock parameters,
+ *		such as rate or parents.
+ *		Returns 0 on success, -EERROR otherwise.
+ *
+ * @terminate:  Free any resource allocated by init.
+ *
+ * @debug_init:	Set up type-specific debugfs entries for this clock.  This
+ *		is called once, after the debugfs directory entry for this
+ *		clock has been created.  The dentry pointer representing that
+ *		directory is provided as an argument.  Called with
+ *		prepare_lock held.  Returns 0 on success, -EERROR otherwise.
+ *
+ *
+ * The clk_enable/clk_disable and clk_prepare/clk_unprepare pairs allow
+ * implementations to split any work between atomic (enable) and sleepable
+ * (prepare) contexts.  If enabling a clock requires code that might sleep,
+ * this must be done in clk_prepare.  Clock enable code that will never be
+ * called in a sleepable context may be implemented in clk_enable.
+ *
+ * Typically, drivers will call clk_prepare when a clock may be needed later
+ * (eg. when a device is opened), and clk_enable when the clock is actually
+ * required (eg. from an interrupt). Note that clk_prepare MUST have been
+ * called before clk_enable.

[PATCH RFC 24/40] clk/ccf: adapt CCF core for U-Boot

[Casey Connolly]

Most of this is just removing locking code and making minor adjustments
to structs. We don't support clkdev since it doesn't seem necessary when
devicetrees are correct.

The most notable change here is in of_clk_get_hw_from_clkspec() where
we find the clock device (which could be of any uclass) and ensure it's
probed, this is necessary so that the clock device can register its
clocks and of_provider with CCF.

The CCF debugfs code is also adapted to be callable from U-Boot.

[PATCH RFC 25/40] clk/ccf: adapt CCF generic clocks for U-Boot

[Casey Connolly]

Adjusted the generic clock drivers so that they build and work in
U-Boot. These changes are fairly minimal, big endian support is dropped
as it's unused anyway, and a small hack is added for sandbox tests which
can't use readl/writel.

The unused spinlock is removed from most function prototypes.

[PATCH RFC 26/40] clk/clk-uclass: adapt for CCF_FULL

[Casey Connolly]

When building U-Boot with CCF_FULL support, most clk operations
are implemented in clk/ccf/clk.c, so we can remove the conflicting
definitions in clk-uclass.c.

Additionally, registering clock consumers works quite differently, so we
adapt clk_get_by_name() and similar functions to call into CCF. Notably
while in Linux the struct clk handle is allocated inside CCF (since
it's an opaque cookie), in U-Boot struct clk is public and typically
allocated by the consumer driver, so we need a small adjustment to allow
CCF to populate an already-allocated struct clk.

[PATCH RFC 27/40] RFC: clk/ccf: add UCLASS_CLK compat shim

[Casey Connolly]

When CCF_FULL is enabled, UCLASS_CLK drivers no longer work normally
since they're entirely invisible to CCF.

This compat shim attempts to bridge the gap by registering a clock
provider with CCF and register clk_hw's on-demand, mapping them
to individual clk IDs of the underlying UCLASS_CLK device. It then
translates between clk_ops and clk_ops_uboot so that clk functions work
as expected.

It's not clear if there is a need for this shim, or if platforms would
instead adjust all of their clock drivers at once. It hasn't been
extensively tested but is provided as-is in case it's useful.

[PATCH RFC 28/40] clk/sandbox: add a CCF_FULL port of clk_sandbox

[Casey Connolly]

This is based on the uCCF version with trivial changes to use the full
CCF API and demonstrate how clk drivers can be ported from U-Boot CCF to
full CCF.

Notably, the line count drops by about 20% with the removal of the
different U_BOOT_DRIVER definitions. It also becomes possible to
register clocks with direct references to their parent clocks, avoiding
the need for global string lookups.

The test dts is also updated to give the clk-ccf device a proper handle
to the fixed osc clock, enabling proper lookup via the clock-names DT
property.

[PATCH RFC 29/40] WIP: test: adjust tests for CCF_FULL

[Casey Connolly]

Fairly minimal changes are needed for the clk_ccf tests to pass, mostly
just disabling the tests related to uCCF implementation details like the
CLK_ID lookups, this is accomplished with a generic wrapper function to
perform the intended lookup through CCF.

The UCLASS_CLK tests are disabled when using CCF_FULL, since it bypasses
UCLASS_CLK entirely.

It is worth noting that not a lot of boards actually use the existing
CCF port under SPL.

	configs$ git grep "CONFIG_SPL=y" | wc -l
	550
	configs$ git grep "CONFIG_SPL_CLK=y" | wc -l
	179
	configs$ git grep "CONFIG_SPL_CLK_CCF=y" | wc -l
	25

As far as I know, this is most likely because that existing CCF is
already quite huge for such a small environment like SPL (SPL_CLK is
already quite big, especially with its dependency on driver model, which
is fine but some devices are so restricted when SPL runs that even
DM is too big to fit). So I wouldn't bother trying to support SPL with
this.

Just wanted to share this, FYI.

As a general question, what is the boot flow for the Qualcomm devices
you are are targeting, i.e. where does U-Boot come in the chain from
reset? Does it use xPL?

Minor point - perhaps CLK_LINUX ? CCF_FULL seems cryptic to me and
some would argue that the existing CLK_CCF is already full..

Perhaps a justification can be expressed in terms of code size / capabilities:

Small - can boot in xPL from limited SRAM, only simple clocks
Medium - smaller code size but still provides good access to clocks
Large - Linux compatible, full capability but lots of code

While those are separate, does this mean that there will be a
significant delta from Linux's clock drivers on Qualcomm, or will it
be minor?

It seems that 1 and 2 could be merged? The question here is how much
effort would someone want to put in. Providing an easy way to pull in
the Linux clock driver makes sense. Some people may wish to put in
effort to at least support the basic clocks for xPL, etc.

Bypassing UCLASS_CLK entirely is a big departure. It means DM can't
track these clock devices properly - no uclass_find_device(), no
sequence numbers, no standard device iteration.

The suggestion to do the same for power domains and resets would
fragment driver model further.

How about having a single UCLASS_CLK_LINUX device?

Driver model normally registers devices during a bind step, which
helps to remove the problem of cyclic dependencies. Is there any need
to wait until probe()? Also, can we statically declare it, to save
code size? Most of the definitions are static

The global ofnode -> device lookup to force probe ordering is
reinventing what DM already does with uclass probing. This feels like
it should integrate with DM rather than work around it.

Probably we should follow Linux, since we would start to lose the
benefit of your series if we merged two structs.

We already struggle with slow pre-relocation performance, something I
have never really dug into.

Sandbox may overestimate the size here, not sure. Ping on irc if you
need update with the buildman setup.

Does this mean that only serial is needed and the clock for it is
already set up by some pre-U-Boot phase?

Can't we allocate struct clk as udevices subdevices of clk drivers ?

Like alloc_clk() woult create a child udevice of dev and the lookup
functions would use the uclass functions and use dm for all the
allocation and lifetime of the clk.

This is what I did for the interconnect, and it works well. You
can easily create/attach/find/iterate/remove subdevices instead
of using custom alloc and lists.

This is what the existing U-Boot CCF does, while we totally could go
with this approach it would involve a lot of changes to CCF to use DM to
manage the clock tree but I don't think we'd gain much.... We'd
basically just end up with the CCF U-Boot already has where every
clk_ops needs it's own driver definition and we have to rely much more
on string based lookups.

If I were writing my own CCF for U-Boot from scratch I could imagine
going this way, clearly it has some value for the existing
implementation... But yeah the allocation and lifetime management is
already just there and battle tested as well as doing some thing DM
alone can't like keeping around but stubbing a clk_core if the provider
is removed without breaking consumers.

Ideally we replace Qualcomms EDK2, but this is only possible on dev
boards and the few secureboot-off devices out there (like the Pocket S2
I've been using for a lot of this work).

In that case we run after Qualcomms SBL which sets up most of the low
level hardware (secure world, always-on co-processor, hyp, DDR training,
etc), of relevance to us the serial port is usually set up as are a few
other things like UFS but we reset that anyway.

On most of the phones though U-Boot is chainloaded, replacing the kernel
in the Android boot flow. This typically means the display is set up so
we get a framebuffer, there are usually some other differences in
hardware state but we try to avoid relying on that and re-init things
ourselves to stay consistent.

I'm not super keen on identifying this functionality just based on the
fact that it's ported from Linux. The existing CLK_CCF in U-Boot is a
"micro" version of CCF built on top of U-Boots driver model, this is
just a fully featured version...

It gets tricky because uCCF (I guess "medium" in your definition?) is
built on top of "small", but full CCF ("large") is a separate standalone
implementation.

I think it might make sense to move the small/medium business logic
(like clk lookup, ops, and clk_set_defaults()) to a separate file and
just have the common functions in clk-uclass.c call into the appropriate
abstraction. It is unfortunate to have this additional layer of
indirection but it should all get nicely inlined by the compiler and
will probably make the code a whole lot more readable heh.

It does affect the gdsc (power domain) and reset drivers but it's not
too bad, this is done in patch 37
(https://source.denx.de/u-boot/custodians/u-boot-snapdragon/-/commit/3673ad5bbc73f7907473f833524fb899abaefd3f)

Basically just adjusting the API, defining a U_BOOT_DRIVER and adding a
function to allocate driver data and bind the child device.

Looking over it again this could be cleaned up quite a bit, the current
code is a bit convoluted since it took a few attempts to find a sensible
implementation.

Yeah, it's obviously platform/board specific but if there's space for
CCF_FULL in SPL (and you get dcache enabled!) then great, but in
basically all cases I think it's a lot more sensible to more tightly
hardcode the clock configuration and use UCLASS_CLK (kinda like what we
do for qcom currently).

Right, better discuss this here than it get lost in the IRC logs heh.

I can appreciate why the old CCF port used the driver model to manage
the clock tree and made each clock its own device, but this comes with
its own set of issues and is kinda abusing DM a bit imo.

The model that CCF implements basically treats clocks as components of a
single device (be that a clk controller, phy, etc). Clocks are not
devices in and of themselves.

With that in mind, I can't really imagine a way to impose the driver
model on CCF, unless I really misunderstand what you mean.

The clock of_provider is at the root of things, if your device has
clocks you register them with CCF and then give CCF a callback function
it can use to map the DT phandle/args from a consumer to the appropriate
clk_hw. This is not all that different to UCLASS_CLK (without CCF)
except the clock driver is entirely responsible for mapping an id to
whatever internal state it needs, much more complexity and cognative
load for anyone reading that code.

struct clk_hw describes how to actually control the clock, it might be
defined statically but that's not something we can assume or enforce
(that's an implementation detail of the clock provider).

In the end, the clock provider device is responsible for ensuring that
clocks (and of_provider) are de-registered with CCF if the driver is
removed. CCF itself only needs to manage the runtime state which it does
through clk_core.

Where I'm a little confused is why do you think DM should "track these
clock devices properly"? If you want to interact with the clock tree you
do that through CCF... Since clocks are independant of devices, devices
of any uclass can provide clocks with CCF, this is how Linux does this
and it makes things soooo much easier.

(small tangent here)

I don't think I can really overstate how much nicer it is... In the case
of the Qualcomm DSI PHY, the earlier U-Boot port had to arbitrarily
split the phy into phy and clock devices, the pll, dividers and mux
can't be easily expressed and propagating rate changes is quite
frustrating. If you want to understand in more detail see the old
version here (start with line 1073):

https://gitlab.com/LinaroLtd/qcom-eco/u-boot/-/blob/casey/8650-pockets2-display/drivers/video/qcom/phy/qcom_dsi_phy.c

And compare that to what we get with CCF:

https://gitlab.com/LinaroLtd/qcom-eco/u-boot/-/blob/casey/ccf-full/drivers/video/qcom/phy/dsi_phy_7nm.c?ref_type=heads#L838

All the complexity is offloaded to CCF!

It depends, today we impose a very strict view that a reset controller
has to be it's own device with (ostensibly) its own state and lifetime,
even though in many cases (like qcom UFS phy) it's really just a single
register on a device that does a lot of other stuff.

If we want to properly model the hardware, a device per DT node
generally feels a lot more appropriate to me. If a device has
"#reset-cells" and registers a reset with the reset core then we can
nicely follow a phandle to the device and get a handle to the correct reset.

The UCLASS model with it's strict limitations has it's advantages for
sure, abstracting a lot of stuff away from subsystems and imposing
order! But maybe it's possible to find a better approach.

Blue sky thinking here, I can't really think of particular reasons why
we need a generic uclass_for_each_device() rather than
subsystem-specific functions (like when do you want to iterate over
every reset device?) except for maybe introspection/debugging which is
for sure good justification.

> 
> How about having a single UCLASS_CLK_LINUX device?

You mean to back the entire CCF? I think this would be pretty convoluted
and not serve any practical purpose.

Being able to keep track of resets/clocks/pds/etc is useful for sure,
but I think we should aim to do this using either the ofnode or the
provider udevice as the handle. This is already built in compared to
adding something like your proposed multi-uclass support.

Maybe it would help if you could expand a bit on why you want DM here,
what are the issues with not using DM to track clocks?

We can't do this statically, this works for like, qcom gcc because there
is only ever one of each clock, but there can be many fixed/divider
clocks so we need to be able to allocate clk_hw at runtime.

Registering clocks during bind would be fine, but it kinda goes against
the lazy-registration philosophy of U-Boot.

Thinking through it a bit more, I don't think it's actually possible to
get in a recursion loop here since device_probe() checks and then sets
the DM_FLAG_ACTIVATED flag. This handles the case where two devices have
assigned-clocks referencing each other or they explicitly fetch clocks
from each other during probe, easily resolved by registering their own
clocks before requesting each others.

If two clocks from different devices reference each other as their
parent I don't *think* that could cause a deadlock either, so we should
be good here. In any case these kinds of issues would only be triggered
by extremely wrong drivers or DT.

Maybe it would be nice to have a recursion counter in
of_clk_get_hw_from_clkspec() and warn if it exceeds some unreasonably
large value, but it's just a QoL issue at that point.

I mean the only difference is doing a global ofnode lookup rather than
uclass_get_device_by_ofnode()... It's not totally ideal since we often
break the 1 device per ofnode assumption but this can be avoided in the
clock provider driver (either dont register the clocks from a child
device or make sure the child is probed when the parent is).

This issue goes away if we eventually reach the point of having a
device-per-ofnode, or we just walk and probe all the children in CCF
(bad hack imo, just use BIND_AFTER_PROBE!).

The full SLOW FDT scan with dcache disabled would be where I'd start ;P

Even with OF_LIVE we walk the FDT pre-reloc which is considerably
slower... It would be great if we could just skip board_f entirely, I
don't think we need to relocate at all on qcom, we can enable dcache and
build OF_LIVE immediately before doing literally anything else...

yeah the sandbox values seemed weird, on ARM64 it looks to be about 8K,
and no size change if CLK_CCF_FULL is disabled.

SPL support on Qualcomm platforms is coming for real. I see a patch-set
already posted and more to come. So we really need to see how Linux CCF
can be reused to support SPL limitations on Qcom SoCs while executing
from on-chip RAM.

If it turns out to be separate clock drivers, Linux CCF for U-Boot
proper and UCLASS_CLK for U-Boot SPL for the same SoC then it's much
more maintainence overhead as compared to just pulling in clk driver
from Linux.

It would be better if somehow Linux CCF can be stripped down to meet SPL
needs too.
