[PATCH v5 00/25] MT8189: Add support for system and base clock controllers

[PATCH v5 00/25] MT8189: Add support for system and base clock controllers

[Louis-Alexis Eyraud]

This series is a continuation by AngeloGioacchino Del Regno and I of a
previous series ([1]), that adds the clock controller support for
the Mediatek MT8189 SoC and its variants (MT8371, MT8391).  

The first major changes is the split of the series in two:
- one for all basic clock controllers including system ones (this
series)
- one for the multimedia and graphics related clock controllers (to be
send in the future)

We chose to separate the multimedia clock drivers from the base system
ones, as there is currently an unsolvable inter-dependency between the
power domains and multimedia clocks; the power domains need a
dual-stage bring-up, where only a part of the multimedia clocks are
accessible in the first power domain powerup stage, and the rest when
the second stage (SRAM enablement) is done.
The current workarounds for this issue, such as removing the is_enabled
operation from the impacted clock controllers clk_ops table or
let the multimedia power domain always on, were quickly discarded
for upstream.

The second major change is the dt-bindings patch ([2]) that got heavily
reworked, not only because of the split choice. We took the opportunity
to regroup in the MT8186 clock and system clock dt-bindings the
description of several other Mediatek SoC (MT8188, MT8192 and MT8195)
and add in them the MT8189 new ones.
The rationale is to ease maintainability and have common files for
several currently supported SoC or new future ones, that have the same
kind of clock controller design.

Finally the pending remarks from peer reviews on the v6 revision of [1]
were also taken into account and new fixes and cleanups were also
added.

A more detailed changelog between [1] and this series:
- Removed multimedia and graphics related clock controllers code and
  definitions from series
- Added new dt-bindings patches to factorise existing MT8188, MT8192
  and MT8195 in MT8186 clock dt-bindings
- Heavily modified the MT8189 dt-bindings to add new compatibles 
  in MT8186 clock dt-bindings
- Created a new dt-bindings include for the MT8189 reset controller
  definitions (include/dt-bindings/reset/mediatek,mt8189-resets.h)
- Removed unnecessary `syscon` compatible fallback from MT8189 base
  clock controllers
- Added missing 'mediatek,mt8189-fhctl' compatible declaration in
  dt-bindings
- Modified Kconfig to COMMON_CLK_MT8189 be tristate (and not bool) to 
  allow all MT8189 clock controller drivers to be built as modules (it
  was partial) 
- Fix pll unregisters in clk_mt8189_apmixed_probe error case
- Reparent several clocks to correct 26M references in clk-mt8189-bus.c,
  clk-mt8189-topckgen.c and clk-mt8189-vlpckgen.c
- Removed CLK_SET_RATE_NO_REPARENT flag from mfg_sel_mfgpll
- Rename TOPCKGEN_fmipi_csi_up26m clock to fmipi_csi_up26m to remove caps usage
- Implemented reset controllers in clk-mt8189-ufs.c
- Updated all file headers to update copyrights and add all authors
- Added all co-developed-by trailers

The series is based on linux-next tree (tag: next-20260730) and has
been tested on Mediatek Genio 520-EVK (MT8371) and 720-EVK (MT8391)
boards, with hardware enablement patch series ([3]), and on Genio
510-EVK (MT8370, variant of MT8188) and Genio 1200-EVK (MT8395,
variant of MT8195).

[PATCH v5 01/25] dt-bindings: clock: mediatek: Make '#clock-cells' required for MT8186

[Louis-Alexis Eyraud]

Both MT8186 clock controllers dt-bindings (clock and sys-clock)
document the '#clock-cells' property but do not enforce it as required
property.
As clock provider nodes should define this property in devicetrees, add
it to the required property list in both its dt-bindings files.

[PATCH v5 05/25] dt-bindings: clock: mediatek: regroup MT8188 dt-bindings into MT8186

[Louis-Alexis Eyraud]

Regroup the MT8188 clock and system clock dt-bindings into MT8186 ones
to ease maintainability and have common files for several currently
supported SoC or new future ones, that have the same kind of clock
controller design.

[PATCH v5 06/25] dt-bindings: clock: mediatek: regroup MT8192 dt-bindings into MT8186

[Louis-Alexis Eyraud]

Regroup the MT8192 clock and system clock dt-bindings into MT8186 ones
to ease maintainability and have common files for several currently
supported SoC or new future ones, that have the same kind of clock
controller design.

[PATCH v5 07/25] dt-bindings: clock: mediatek: regroup MT8195 dt-bindings into MT8186

[Louis-Alexis Eyraud]

Regroup the MT8195 clock and system clock dt-bindings into MT8186 ones
to ease maintainability and have common files for several currently
supported SoC or new future ones, that have the same kind of clock
controller design.

[PATCH v5 08/25] dt-bindings: clock: mediatek: Add MT8189 system/base clocks and resets

[Louis-Alexis Eyraud]

Add compatible and binding headers files for system and base clock
controllers and reset controllers support of MediaTek MT8189 SoC.
The MT8189 clock IP provide clock control for main system (apmixedsys,
topcksys and vlpcksys) and subsys (eg. peri, scp, ufs...).

Also, add compatible for frequency hopping and spread spectrum clock
functionality.

[PATCH v5 09/25] clk: mediatek: Harmonize mtk_pll_fenc related symbol names

[Louis-Alexis Eyraud]

To prepare for the new clock ops set addition, with support for set/clr
enable logic only, rename mtk_pll_fenc_setclr_ops and its callback names
to harmonize the naming with the same suffix.

[PATCH v5 10/25] clk: mediatek: pll: Add BAR reset register offsets

[Louis-Alexis Eyraud]

Currently, the register offset to handle BAR reset, for PLLs that
support it, is hardcoded to CON0.
On MT8189 SoC, there are separate status, set and clr registers to
handle this, so differents offsets are needed.

Add the new fields for offsets and addresses to the MTK PLL data
structure and modify mtk_clk_register_pll_ops function to compute the
new register addresses so they are available for clock operation usage.

Also, replace reset BAR address computing by its computed address
from MTK PLL data structure in prepare/unprepare callbacks.

[PATCH v5 11/25] clk: mediatek: pll: Factorise pll power on/off sequences

[Louis-Alexis Eyraud]

In order to prepare the MT8189 SoC support, that requires different
registers to control PLL status and perform reset BAR, and so a
different sets of clock operations, split the pll power on and off
sequences from mtk_pll_prepare/unprepare functions into private
subfunctions.

[PATCH v5 13/25] clk: mediatek: pll: Add ops for PLLs using set/clr regs

[Louis-Alexis Eyraud]

MT8189 SoC uses a new combination of status and set/clr registers to
control its PLL enable state and perform BAR reset, that are different
than the current default clock prepare/unprepare operations are using.

Add new set of PLL clock operations to support this logic that relies
on the following registers for prepare/unprepare operations:
  - en/en_set/en_clr, rather than en register, for PLL enable
    control
  - rst_bar/rst_bar_set/rst_bar_clr, rather than default rst_bar
    register for BAR reset control

Also, handle rst_bar register setting/clearing with a timeout, to
verify the operation was correctly performed.

[PATCH v5 14/25] clk: mediatek: pllfh: Add configurable clock ops to mtk_pllfh_data

[Louis-Alexis Eyraud]

Currently, the mtk_clk_register_pllfh functions always registers the
default PLL clock operation set (mtk_pllfh_ops). This does not allow
use a custom one, for SoC such as MT8189, that needs different
set with support for set/clr enable.

Add a new field for the ops to register in mtk_pllfh_data structure
and use this new field to either register it when not null or the
default ops otherwise.

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [High] The newly introduced `rst_bar_set_addr` and `rst_bar_clr_addr` are completely unused in the `mtk_pll_prepare` and `mtk_pll_unprepare` callbacks, causing read-modify-writes to be performed on the status register instead of writing to the dedicated set/clear registers.

clk: mediatek: pll: Add BAR reset register offsets

This commit introduces new fields to the MTK PLL data structure to support
separate reset BAR status, set, and clear registers on the MT8189 SoC. It
also updates the prepare and unprepare callbacks to use the newly computed
reset BAR address instead of hardcoding the CON0 register offset.

[Severity: High]
Does this logic correctly handle the new set and clear registers for MT8189?

The commit message mentions that MT8189 has separate set and clr registers 
to handle the reset BAR. However, this code continues to perform a 
read-modify-write on the status register (rst_bar_addr) instead of writing
to the newly added rst_bar_set_addr. 

Will this fail to assert the reset BAR on MT8189 hardware that requires
the dedicated set register?

[Severity: High]
Similarly, shouldn't this unprepare path write to rst_bar_clr_addr if it is 
available, rather than doing a read-modify-write on the status register?

[Severity: Medium]
Is the conditional block wrapping this list missing a `contains:` keyword 
before the `enum:`?

Because `compatible` strings are arrays in the device tree, comparing them 
directly to a scalar string list using `enum:` will always evaluate to false. 

As a result, the requirement for `#reset-cells` will not be enforced for 
these newly added hardware variants, allowing incomplete device tree nodes 
to silently pass schema validation.

Does this compatible match logic need a "contains:" keyword?

Since the compatible property is evaluated as a string array, matching a list
of scalar strings directly against it without "contains:" will always evaluate
to false.

Without "contains:", does this mean the schema will skip the "then" branch
and incorrectly apply the "else" branch ('#reset-cells': false) to all MT8188
nodes, causing correct device trees to fail dtbs_check and allowing incomplete
ones to pass?

[Severity: Medium]
Does this file's allOf block incorrectly evaluate the compatible strings?

Looking further down in the same file:

Documentation/devicetree/bindings/clock/mediatek,mt8186-clock.yaml:allOf:
  allOf:
    - if:
        properties:
          compatible:
            enum:
              - mediatek,mt8188-camsys-rawa

Because the compatible property is evaluated as an array in Device Tree schemas,
does using enum directly instead of contains: enum: cause the if condition
to always evaluate to false?

If it fails to match the array, it appears validation falls through to the
else block, incorrectly enforcing '#reset-cells': false for MT8188 device nodes
that actually require resets.

Should this use contains: enum: instead to properly validate the hardware
variants?

clk: mediatek: pll: Add ops for PLLs using set/clr regs

This commit introduces a new set of PLL clock operations for the MT8189 SoC.
It utilizes set/clear registers for enabling PLLs and controlling BAR resets
instead of the default clock prepare/unprepare operations.

[Severity: Medium]
Does using readl_poll_timeout() here introduce unnecessary latency?

Since RST_BAR_TIMEOUT is only 20us, specifying a 1us delay translates to
usleep_range(1, 1). Due to hrtimer and context switching overhead, this will
often sleep for much longer than the intended 20us total timeout.

Would it be better to use readl_poll_timeout_atomic() here to avoid the
scheduling overhead for such a short hardware timeout?

[Severity: Medium]
Similarly, should this use readl_poll_timeout_atomic() instead?

The 1us delay on the clock unprepare path will cause the same sleeping
overhead and context switching latency as in mtk_pll_prepare_setclr().

[Severity: High]
Does this global static array retain stale state across driver unbind and rebind
cycles?

fhctl_parse_dt() maps the FHCTL device node into memory and stores the pointer
in this static array, setting state.fh_enable = 1.

On driver unbind, mtk_clk_unregister_pllfhs() calls iounmap() on this pointer
but does not clear state.fh_enable or state.base.

If the driver is later re-bound and fhctl_parse_dt() fails (for example, if
of_iomap() fails), the array retains the old values.

When mtk_clk_register_pllfhs() executes, it will see fh_enable == 1 and attempt
to access the previously unmapped memory via pllfh_data->state.base, causing an
I/O use-after-free.

[Severity: High]
This is a pre-existing issue, but I noticed that fhctl_parse_dt() can use an
uninitialized variable.

In drivers/clk/mediatek/clk-pllfh.c:fhctl_parse_dt():

	u32 num_clocks, pll_id, ssc_rate;
	...
		of_property_read_u32_index(node,
					   "mediatek,hopping-ssc-percent",
					   i, &ssc_rate);

		pllfh = get_pllfh_by_id(pllfhs, num_fhs, pll_id);
		if (!pllfh)
			continue;

		pllfh->state.fh_enable = 1;
		pllfh->state.ssc_rate = ssc_rate;

If the "mediatek,hopping-ssc-percent" property is missing from the device tree,
of_property_read_u32_index() returns an error and leaves ssc_rate untouched.
The uninitialized stack garbage is then unconditionally stored in
pllfh->state.ssc_rate.

Since this value is later used to program hardware registers, could it cause
erratic clock frequencies or system instability?

[Severity: Medium]
Does this error path leak the FHCTL I/O memory mapping?

fhctl_parse_dt() maps the FHCTL device node into memory. If
mtk_clk_register_pllfhs() fails, the driver jumps directly to
free_apmixed_data and exits without unmapping the FHCTL memory.

Because this can happen on probe deferral, repeated failures could leak
virtual memory space.

[Severity: High]
Can this devres-managed registration cause a use-after-free if probe fails?

During probe, if a later step (like of_clk_add_hw_provider) fails in
__mtk_clk_simple_probe(), the error path manually unregisters and frees all
clocks before returning:

drivers/clk/mediatek/clk-mtk.c:__mtk_clk_simple_probe() {
    ...
unregister_muxes:
	if (mcd->mux_clks)
		mtk_clk_unregister_muxes(mcd->mux_clks,
					 mcd->num_mux_clks, clk_data);
    ...
}

After the error is returned, the driver core cleans up devres allocations,
which invokes clk_notifier_unregister() with the now-freed clk pointer. This
dereferences the freed pointer:

drivers/clk/clk.c:clk_notifier_unregister() {
    ...
	list_for_each_entry(cn, &clk_notifier_list, node) {
		if (cn->clk == clk) {
			ret = srcu_notifier_chain_unregister(&cn->notifier_head, nb);

			clk->core->notifier_count--;
    ...
}

Should this notifier be manually unregistered on the error path before the
clocks are freed, instead of relying on devres?

[Severity: High]
This is a pre-existing issue, but I noticed this driver relies on
mtk_clk_simple_probe(), which appears to have a use-after-free on its error
path.

In drivers/clk/mediatek/clk-mtk.c:__mtk_clk_simple_probe(), the clock
provider is registered via of_clk_add_hw_provider(). If the subsequent reset
controller registration fails, the code jumps to unregister_clks:

	r = mtk_register_reset_controller_with_dev(&pdev->dev,
						   mcd->rst_desc);
	if (r)
		goto unregister_clks;

The cleanup path then frees clk_data without unregistering the clock provider
first:

unregister_clks:
	mtk_clk_unregister_gates(mcd->clks, mcd->num_clks, clk_data);
free_data:
	mtk_free_clk_data(clk_data);

Because of_clk_del_provider() is never called on this error path, the OF
provider list retains a dangling pointer to the freed clk_data. Could a
subsequent clk_get() that matches this provider's device node dereference
the freed memory?

clk: mediatek: Add MT8189 ufs clock support

This commit adds support for the MT8189 ufs clock controller. It provides
clock gate control and reset capabilities for Universal Flash Storage on the
MT8189 SoC.

[Severity: High]
This is a pre-existing issue, but does the error path in
__mtk_clk_simple_probe() leave a dangling pointer in the OF clock provider
list if reset controller registration fails?

When mtk_register_reset_controller_with_dev() fails, the code jumps to
unregister_clks:

drivers/clk/mediatek/clk-mtk.c:__mtk_clk_simple_probe() {
    ...
	if (mcd->rst_desc) {
		r = mtk_register_reset_controller_with_dev(&pdev->dev,
							   mcd->rst_desc);
		if (r)
			goto unregister_clks;
	}
    ...
unregister_clks:
	if (mcd->clks)
		mtk_clk_unregister_gates(mcd->clks, mcd->num_clks, clk_data);
...
free_data:
	mtk_free_clk_data(clk_data);
}

The unregister_clks error path frees clk_data but appears to miss calling
of_clk_del_provider() if of_clk_add_hw_provider() had already succeeded. 

Could this cause a use-after-free if a subsequent clock lookup invokes
of_clk_hw_onecell_get() with the freed clk_data pointer? Since this new
driver registers a reset controller and uses this probe function, it might
be exposed to this vulnerable error path if reset registration fails.
