Add initial support for the Synaptics SL261X SoCs and corresponding
RDK boards.
The SL261X SoCs include five pin-to-pin compatible SoCs: SL2611, SL2613,
SL2615, SL2617, and SL2619.
Only reset, pinctrl, clk/pll, uart, gpio, i2c, spi, i3c are included in
this series. The support for Ethernet, USB, SDHCI, CAN, DMAC, XSPI will
be submitted after this series is merged.
since v1:
- rebase on latest rcN
- drop some patches which have been merged
- let the "gbl" node export pinctrl/reset/clk devices with
MFD_CELL_NAME()
- use <linux/platform_device.h> instead of <linux/mod_devicetable.h>
- adopt some coding suggestions from Uwe
- Use 0 and 1 to select normal and strong pull-up on 10-bit pads
- collect Acked-by tag

For Android GKI + vendor_dlkm deployments, where vendor-specific
drivers must be kept separate from the GKI vmlinux and loaded as
modules from the vendor partition, we need to enable module build
support for berlin pinctrl drivers.
To acchive this goal:
1.Use devm_* APIs to alloc memory, so that we don't need to care free when
unloading.
2.Export two symbols which will be used by SoC pinctrl drivers.
3.Add MODULE_LICENSE and MODULE_DESCRIPTION

Describe the SoC, MCU, AVIO and CPU system control blocks, including their
clock inputs, clock and reset providers, and pin configuration subnodes.
The clock and reset providers share each register block node.
Add the clock and reset identifiers used by consumers of these blocks.

+description: |
+ The SL2610 family has separate SoC, MCU, AVIO, and CPU system control
+ register blocks. The SoC and MCU blocks provide clocks, resets, and pin
+ control. The CPU block provides clocks. The AVIO block contains audio PLLs.
+
+ Clock and reset specifiers refer directly to the system control node.
+ Pin group configurations are direct children of the SoC or MCU node.
+ There are no separate clock, reset, or pin controller child nodes.

Create the clock, reset and pin controller platform devices implemented
by each SL2610 system control block. Select the appropriate MFD cells
from per-block compatible data while keeping register access available
through the shared syscon.

Support the SoC and MCU reset controls exposed by the SL2610 system
controllers. Match the MFD-created platform devices, use the parent
syscon regmap and register each reset provider against the parent DT node.
Handle both pulse resets and sticky resets with assert/deassert controls.

Add the SoC and MCU pin groups and mux functions for SL2610, together
with their pad configuration register descriptions. Bind to the platform
devices created by the system controller and associate pin configurations
with the parent syscon DT node.

Add the configurable divider and gate clock implementation shared by
Synaptics system controllers. Provide the MCU system manager helper for
registering its fixed clocks, gates and peripheral dividers.
Keep clock resources managed by the MFD clock device and obtain the
register range and provider node from its parent.

Support the SL2610 SoC, CPU, AVIO and MCU clocks. Register the PLL
outputs and the divider, gate and fixed-factor clocks used by the CPU
and peripherals.
Match MFD platform devices and register clock providers on their parent
system controller nodes.

Describe the CPUs, interrupt controller, system controllers and supported
serial, I2C, I3C, SPI and GPIO peripherals for the SL2610 family.
Use the SL2610 peripheral compatibles already documented in the upstream
bindings and share clock, reset and pin configuration providers through
the system controller nodes.

soc: synaptics: add SL2610 system controller support
This commit adds a driver for the Synaptics SL2610 system control blocks to
register their clock, reset, and pin controller child devices via MFD.

[Severity: Low]
Should this driver live under drivers/mfd/ instead of drivers/soc/synaptics/?
sl2610-syscon.c does not implement any SoC bus or SoC-specific service and
only calls devm_mfd_add_devices() to instantiate MFD child devices. New core
MFD drivers and new calls to devm_mfd_add_devices() belong in drivers/mfd/.

[Severity: Low]
Why use MFD for the single-function AVIO and CPU clock blocks?
sl2610_avio_cells and sl2610_cpu_cells each register only a single clock
child device, and per the syna,sl2610-soc-syscon binding neither block
provides reset or pinctrl functions. MFD is intended for devices that
register multiple children across different subsystems, whereas the clock
driver can bind directly to syna,sl2610-avio-syscon and
syna,sl2610-cpu-syscon while keeping shared regmap access through the
generic syscon compatible.

[Severity: Low]
This isn't a bug in normal DT probing, but MFD drivers should not pass
mfd_cell arrays through the .data field of of_device_id tables. In addition,
if the driver is bound without an OF match (such as via sysfs
driver_override), device_get_match_data() returns NULL and
sl2610_syscon_probe() dereferences a NULL data pointer.
Could sl2610_syscon_of_match store an enum or integer ID in .data and select
the static const mfd_cell array with a switch statement (and a default error
return) in sl2610_syscon_probe()?

[Severity: Medium]
Should the pad configuration offset for GPIO54 be 0x887c instead of 0x87c?
All other entries in sl2610_soc_pinctrl_groups place conf_offset at 4-byte
intervals in the 0x8800..0x88ec range, so configuring pad parameters for
GPIO54 will read and modify offset 0x87c in the parent syscon regmap while
leaving GPIO54's pad unconfigured.

[Severity: Low]
Should these dissimilar system controller blocks be split into separate
binding schemas instead of combining them with three per-compatible
if-then-else blocks in allOf?
Only the SoC and MCU blocks provide resets and pin mux subnodes, only the
CPU block uses syna,gbl-syscon, and the AVIO block exposes none of these
providers. Splitting the schema by block role would avoid toggling most
properties and patternProperties per compatible.

[Severity: Medium]
Can berlin.c actually be built as a loadable module when
drivers/pinctrl/berlin/Kconfig still defines the symbol as bool and
drivers/pinctrl/berlin/Makefile builds berlin.o with obj-y?
drivers/pinctrl/berlin/Kconfig:
config PINCTRL_BERLIN
bool
drivers/pinctrl/berlin/Makefile:
obj-y += berlin.o
Even when a downstream SoC pinctrl driver is configured as a module,
selecting this symbol forces berlin.o into vmlinux instead of building a
loadable module for vendor_dlkm.

Author: Jisheng Zhang <jszhang@kernel.org>
pinctrl: berlin: add optional pinconf support
This commit adds generic pin configuration support (bias, drive strength,
input enable, Schmitt trigger, and slew rate) to the Berlin pinctrl driver
for 8-bit and 10-bit group configuration registers.

[Severity: Low]
Does this over-allocate *map when num_configs > 1?
pinctrl_utils_add_map_configs() packs all num_configs entries for a group
into a single PIN_MAP_TYPE_CONFIGS_GROUP map slot, so each group uses at
most two map entries (ngroups * (!!num_configs + 1) in total), leaving
ngroups * (num_configs - 1) reserved entries unused.

[Severity: Medium]
Does the error path leak *map and any per-group config arrays already
duplicated by pinctrl_utils_add_map_configs()?
When ops->dt_node_to_map() returns a negative error code, the caller
dt_to_map_one_config() in drivers/pinctrl/devicetree.c returns immediately
without freeing the partially constructed map. If
pinctrl_utils_add_map_mux() or pinctrl_utils_add_map_configs() fails in the
loop after pinctrl_utils_reserve_map() allocated *map, jumping to exit only
frees the temporary configs array and leaks *map along with any configs
duplicated for earlier groups. Calling pinctrl_utils_free_map(pctrl_dev,
*map, *num_maps) when ret < 0 would clean these up.

[Severity: Low]
Does querying PIN_CONFIG_SLEW_RATE fail with -EINVAL whenever the slew rate
bit is 0?
berlin_pinconf_group_set() accepts 0 as a valid slew-rate argument to clear
PINCFG_SL_10BIT or PINCFG_SL_8BIT, but berlin_pinconf_group_get() sets
enabled from that bit and returns -EINVAL when enabled is false, so a slew
rate of 0 cannot be read back (for example via debugfs pinconf-groups).
Setting enabled = true as in the PIN_CONFIG_DRIVE_STRENGTH case would allow
both 0 and 1 to be reported.

[Severity: Medium]
Should berlin_pinconf_group_get() and berlin_pinconf_group_set() return
-ENOTSUPP instead of -EOPNOTSUPP when !conf_bits or when param is not
supported?
With .is_generic = true, reading debugfs pinconf-groups calls
pinconf_generic_dump_one(), which queries every generic parameter in
conf_items[] and only treats -EINVAL and -ENOTSUPP as legal responses:
drivers/pinctrl/pinconf-generic.c:pinconf_generic_dump_one() {
...
ret = pin_config_group_get(dev_name(pctldev->dev),
pindesc->name, &config);
/* These are legal errors */
if (ret == -EINVAL || ret == -ENOTSUPP)
continue;
if (ret) {
seq_printf(s, "ERROR READING CONFIG SETTING %d ", i);
continue;
}
...
}
Returning -EOPNOTSUPP causes debugfs pinconf-groups to print "ERROR READING
CONFIG SETTING" for every unsupported parameter and for any group with
conf_bits == 0.

[Severity: Low]
Should SL2610_PLL also depend on OF && HAS_IOMEM like SL2610_CLK?
sl2610-pll.c calls readl_relaxed() and of_clk_get().
Also, both symbols allow COMPILE_TEST when ARCH_BERLIN=n, but
drivers/clk/Makefile only descends into berlin/ for CONFIG_ARCH_BERLIN, so
neither driver is built under COMPILE_TEST=y with ARCH_BERLIN=n.

[Severity: Low]
Are "apbuart3lck" and "apbi2c1lck" typos for "apbuart3clk" and
"apbi2c1clk"? Every other entry in sl2610_gates[] ends with "clk", so
these two clocks are registered under misspelled names in clk_summary and
any lookup by name.

[Severity: Medium]
Can registering the MCU gate clocks via sl_sysmgr_clk_setup() cause an IRQ
lock inversion or deadlock on sl_sysmgr_gateclk_lock?
In commit "clk: berlin: add Synaptics clock controller helpers",
sl_sysmgr_gateclk_enable() and sl_sysmgr_gateclk_is_enabled() acquire
sl_sysmgr_gateclk_lock with guard(spinlock) instead of
guard(spinlock_irqsave):
drivers/clk/berlin/sl-sysmgr-clk.c:sl_sysmgr_gateclk_is_enabled() {
struct sl_sysmgr_gateclk *gclk = to_sl_sysmgr_gateclk(hw);
u32 reg;
guard(spinlock)(&sl_sysmgr_gateclk_lock);
reg = readl_relaxed(gclk->reg);
...
}
clk_enable() holds the CCF enable_lock with interrupts disabled (and may
run in hardirq context) before calling .enable, whereas
clk_summary_show_one() and clk_hw_is_enabled() call .is_enabled from
process context without enable_lock and with interrupts enabled:
CPU0 CPU1
---- ----
clk_enable()
clk_enable_lock()
spin_lock_irqsave(&enable_lock)
clk_summary_show_one()
clk_core_is_enabled()
sl_sysmgr_gateclk_is_enabled()
spin_lock(&sl_sysmgr_gateclk_lock)
sl_sysmgr_gateclk_enable()
spin_lock(&sl_sysmgr_gateclk_lock)
<hardirq>
clk_enable()
clk_enable_lock()
spin_lock_irqsave(&enable_lock)
*** DEADLOCK ***
A single-CPU deadlock also occurs if the interrupt on the same CPU calls
clk_enable() on an MCU gate clock while sl_sysmgr_gateclk_is_enabled()
holds sl_sysmgr_gateclk_lock. Using guard(spinlock_irqsave) (or reading
gclk->reg locklessly in sl_sysmgr_gateclk_is_enabled() as sl_clk_is_enabled()
does) avoids this.

[Severity: Medium]
Does sl2610_pll_register() dereference dev and dev->parent before the !dev
check? If dev or dev->parent is NULL, initializing np at the top of the
function causes a NULL pointer dereference instead of returning -EINVAL.
sl2610_soc_clk_setup(), sl2610_cpu_clk_setup(), and sl2610_aio_clk_setup()
in drivers/clk/berlin/clk-sl2610.c also dereference dev->parent->of_node
without checking dev->parent.

This isn't a bug, but struct clk_hw_onecell_data and struct device_node in
sl2610-pll.h and the empty SL2610_APLL macro in sl2610-pll.c are unused and
can be dropped.

[Severity: High]
Can taking sl_sysmgr_gateclk_lock with guard(spinlock) instead of
spinlock_irqsave deadlock?
clk_core_is_enabled() calls .is_enabled from process context without
holding enable_lock and with local interrupts enabled (for example via
clk_summary_show_one() or __clk_is_enabled()), while clk_enable() can be
called from hardirq context:
clk_summary_show_one()
...
sl_sysmgr_gateclk_is_enabled()
spin_lock(&sl_sysmgr_gateclk_lock)
<hardirq>
clk_enable()
...
sl_sysmgr_gateclk_enable()
spin_lock(&sl_sysmgr_gateclk_lock) <-- spins forever
sl_sysmgr_gateclk_enable() needs guard(spinlock_irqsave), while
sl_sysmgr_gateclk_is_enabled() only performs a single readl_relaxed() and
does not need the lock.

[Severity: Medium]
Should sl_sysmgr_gateclk_ops and sl_sysmgr_clk_ops implement .disable
callbacks?
Without .disable, consumer calls to clk_disable() and late boot's
clk_disable_unused() cannot gate these clocks in hardware, and
clk_is_enabled_when_prepared() treats them as enabled by .prepare even
though .prepare is not implemented. In addition, struct sl_sysmgr_gateclk
and struct sl_sysmgr_gateclk_desc duplicate devm_clk_hw_register_gate()
and struct sl_gateclk_desc in drivers/clk/berlin/sl-clk.h.

[Severity: Medium]
Does leaving struct clk_init_data init uninitialized on the stack in
sl_sysmgr_gateclk_register() and sl_sysmgr_clk_register() pass garbage
init.parent_data and init.parent_hws pointers into devm_clk_hw_register()?
clk_core_populate_parent_map() reads init->parent_hws and
init->parent_data unconditionally when registering the clock.

[Severity: Medium]
Does sl_sysmgr_clk_setup() drop the flags field from gdescs[i] and
descs[i]?
struct sl_sysmgr_gateclk_desc and struct sl_sysmgr_clk_desc both define an
unsigned long flags member, but sl_sysmgr_clk_setup() never passes them to
sl_sysmgr_gateclk_register() or sl_sysmgr_clk_register(), which hardcode
init.flags = 0 and ignore flags such as CLK_IS_CRITICAL or
CLK_IGNORE_UNUSED.

[Severity: Low]
Does sl-sysmgr-clk.h need #include <linux/types.h> and a forward
declaration of struct platform_device so it is self-contained when
included before other headers? Also, <linux/version.h> and DIV_CHNG_EN in
sl-sysmgr-clk.c are unused, and sl-clk.h uses u32 and u8 without directly
including <linux/types.h>.

arm64: dts: synaptics: add SL2610 family RDK boards
This commit adds device tree files for the Synaptics SL2611, SL2613,
SL2615, SL2617, and SL2619 reference development kits along with a shared
common dtsi.

[Severity: Low]
Is the dt-bindings/input/linux-event-codes.h include needed here? Neither
sl261x-rdk-common.dtsi nor the board dts files that include it define any
input nodes or reference event code macros.

[Severity: Low]
Should cpu@0 use cpu-supply instead of cpu0-supply?
Documentation/devicetree/bindings/arm/cpus.yaml marks cpu0-supply as
deprecated in favor of cpu-supply, and the dual-core SL2615, SL2617, and
SL2619 variants also define cpu1: cpu@100.

[Severity: Low]
Should the node name soc_i2c0-pmux use a hyphen instead of an underscore
(for example, soc-i2c0-pmux)? Using an underscore in a devicetree node
name triggers a dtc node_name_chars_strict warning when building with W=2.

reset: add Synaptics SL2610 reset controller support
This commit adds a reset controller driver for the SoC and MCU system
control blocks on Synaptics SL2610 SoCs, supporting both pulse and sticky
reset lines.

[Severity: Medium]
Should sl2610_reset_assert() and sl2610_reset_deassert() return -ENOTSUPP
(or 0 in sl2610_reset_deassert()) instead of -EINVAL when !cfg->sticky?
In drivers/reset/core.c, reset_control_deassert() treats self-deasserting
pulse reset lines as deasserted by default when .deassert() is not
implemented, and documents that .deassert() should return -ENOTSUPP when
deassertion cannot be guaranteed:
drivers/reset/core.c:reset_control_deassert() {
...
/*
* If the reset controller does not implement .deassert(), we assume
* that it handles self-deasserting reset lines via .reset(). In that
* case, the reset lines are deasserted by default. If that is not the
* case, the reset controller driver should implement .deassert() and
* return -ENOTSUPP.
*/
if (!rcdev->ops->deassert)
return 0;
...
}
Because this controller implements .assert() and .deassert() for its
sticky lines, returning -EINVAL for the 22 pulse reset lines in
sl2610_reset_cfgs[] causes consumer drivers that call
reset_control_deassert() during probe (such as 8250_dw) to fail probe, and
prevents consumers such as stmmac_dvr_probe() from checking for -ENOTSUPP
on reset_control_assert() and falling back to reset_control_reset().

Author: Jisheng Zhang <jszhang@kernel.org>
arm64: dts: synaptics: add SL2610 family SoCs
This commit adds devicetree files for the Synaptics SL2610 family SoCs
(SL2611, SL2613, SL2615, SL2617, and SL2619), describing CPUs, GIC,
system controllers, and serial, I2C, I3C, SPI, and GPIO peripherals.

[Severity: Low]
Should the optee node be placed under a /firmware container node?
Documentation/devicetree/bindings/arm/firmware/linaro,optee-tz.yaml
places optee under /firmware, which of_platform_default_populate_init()
looks up directly via of_find_node_by_path("/firmware") before populating
the rest of the tree.

[Severity: Low]
This isn't a bug, but sl2617.dtsi and sl2619.dtsi duplicate the entire
cpu1 and pmu definitions from sl2615.dtsi. Could they include
sl2615.dtsi and override the root compatible property, the same way
sl2613.dtsi includes sl2611.dtsi?

[Severity: Low]
Is the root node missing compatible = "syna,sl2619"; here?
Unlike sl2615.dtsi and sl2617.dtsi, sl2619.dtsi does not override the
root compatible property and inherits compatible = "syna,sl2613"; from
sl2613.dtsi.
