8bfc651a28 pwm: pca9685: Switch i2c driver back to use .probe()
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter")
convert back to (the new) .probe() to be able to eventually drop
.probe_new() from struct i2c_driver.

38ba835986 pwm: sysfs: Do not apply state to already disabled PWMs
If the PWM is exported but not enabled, do not call pwm_class_apply_state().
First of all, in this case, period may still be unconfigured and this would
make pwm_class_apply_state() return -EINVAL, and then suspend would fail.
Second, it makes little sense to apply state onto PWM that is not enabled
before suspend.

Failing case:
"
$ echo 1 > /sys/class/pwm/pwmchip4/export
$ echo mem > /sys/power/state
...
pwm pwmchip4: PM: dpm_run_callback(): pwm_class_suspend+0x1/0xa8 returns -22
pwm pwmchip4: PM: failed to suspend: error -22
PM: Some devices failed to suspend, or early wake event detected
"

Working case:
"
$ echo 1 > /sys/class/pwm/pwmchip4/export
$ echo 100 > /sys/class/pwm/pwmchip4/pwm1/period
$ echo 10 > /sys/class/pwm/pwmchip4/pwm1/duty_cycle
$ echo mem > /sys/power/state
...
"

Do not call pwm_class_apply_state() in case the PWM is disabled
to fix this issue.

329db102a2 pwm: meson: make full use of common clock framework
Newer versions of the PWM block use a core clock with external mux,
divider, and gate. These components either don't exist any longer in
the PWM block, or they are bypassed.
To minimize needed changes for supporting the new version, the internal
divider and gate should be handled by CCF too.

I didn't see a good way to split the patch, therefore it's somewhat
bigger. What it does:

- The internal mux is handled by CCF already. Register also internal
  divider and gate with CCF, so that we have one representation of the
  input clock: [mux] parent of [divider] parent of [gate]

- Now that CCF selects an appropriate mux parent, we don't need the
  DT-provided default parent any longer. Accordingly we can also omit
  setting the mux parent directly in the driver.

- Instead of manually handling the pre-div divider value, let CCF
  set the input clock. Targeted input clock frequency is
  0xffff * 1/period for best precision.

- For the "inverted pwm disabled" scenario target an input clock
  frequency of ULONG_MAX. This ensures that the remaining low pulses
  have minimum length.

I don't have hw with the old PWM block, therefore I couldn't test this
patch. With the not yet included extension for the new PWM block
(channel->clk coming directly from get_clk(external_clk)) I didn't
notice any problem. My system uses PWM for the CPU voltage regulator
and for the SDIO 32kHz clock.

Note: The clock gate in the old PWM block is permanently disabled.
This seems to indicate that it's not used by the new PWM block.

3bddf73285 pwm: meson: don't use hdmi/video clock as mux parent
The meson_vclk code from the display driver may change the rate of the
video clock. Therefore better don't use it as pwm mux parent.
After removing this clock from the parent list pwm_gxbb_data and
pwm_g12a_ee_data are the same as pwm_meson8b_data. So we can remove
them.

6b9352f3f8 pwm: meson: modify and simplify calculation in meson_pwm_get_state
I don't see a reason why we should treat the case lo < hi differently
and return 0 as period and duty_cycle. The current logic was added with
c375bcbaab ("pwm: meson: Read the full hardware state in
meson_pwm_get_state()"), Martin as original author doesn't remember why
it was implemented this way back then.
So let's handle it as normal use case and also remove the optimization
for lo == 0. I think the improved readability is worth it.

Commit 08384e80a7 ("MIPS: DTS: CI20: Fix ACT8600 regulator node
names") caused the VDDCORE power supply (regulated by the ACT8600's
DCDC1 output) to drop from a voltage of 1.2V configured by the
bootloader, to the 1.1V set in the Device Tree.

According to the documentation, the VDDCORE supply should be between
0.99V and 1.21V; both values are therefore within the supported range.

However, VDDCORE being 1.1V results in the CI20 being very unstable,
with corrupted memory, failures to boot, or reboots at random. The
reason might be succint drops of the voltage below the minimum required.

Raising the minimum voltage to 1.125 volts seems to be enough to address
this issue, while still keeping a relatively low core voltage which
helps for power consumption and thermals.

877e91191c leds: leds-mt6323: Adjust return/parameter types in wled get/set callbacks
Clang's kernel Control Flow Integrity (kCFI) is a compiler-based
security mitigation that ensures the target of an indirect function call
matches the expected type of the call and trapping if they do not match
exactly. The warning -Wincompatible-function-pointer-types-strict aims
to catch these issues at compile time, which reveals:

 drivers/leds/leds-mt6323.c:598:49: error: incompatible function pointer types assigning to 'int (*)(struct led_classdev *, enum led_brightness)' from 'int (struct led_classdev *, unsigned int)' [-Werror,-Wincompatible-function-pointer-types-strict]

 2 errors generated.

While 'unsigned int' is ABI compatible with 'enum led_brightness' (hence
no warning from -Wincompatible-function-pointer-types) and the callers
of these callbacks use/pass the values as 'unsigned int', the mismatch
between the prototype and the called function will trip kCFI at runtime.

Change the types in the implementations to match the prototypes, clearing
up the warning and avoiding kCFI failures.

1471d85ffb s390/ctcm: Convert sprintf/snprintf to scnprintf
This LWN article explains the why scnprintf is preferred over snprintf
in general
https://lwn.net/Articles/69419/
Ie. snprintf() returns what *would* be the resulting length, while
scnprintf() returns the actual length.

Note that ctcm_print_statistics() writes the data into the kernel log
and is therefore not suitable for sysfs_emit(). Observable behavior is
not changed, as there may be dependencies.

All sysfs related show()-functions should only use sysfs_emit() or
sysfs_emit_at() when formatting the value to be returned to user space.
