This driver is a platform driver. The probe function can be called after
kernel init, and try to reference kernel memory that has been freed.
Drop the __init markings everywhere here to avoid referencing initdata
from non-init code. Fixes modpost warnings.

This increases the maxmium supported frequency on 32-bit systems from
2^31 (signed long as used by clk_ops.round_rate, maximum value:
approx. 2.14GHz) to 2^32 (unsigned long as used by
clk_ops.determine_rate, maximum value: approx. 4.29GHz).
On Meson8/8b/8m2 the HDMI PLL and it's OD (post-dividers) are
capable of running at up to 2.97GHz. So switch the divider
implementation in clk-regmap to clk_ops.determine_rate to support these
higher frequencies on 32-bit systems.

.determine_rate is meant to replace .round_rate. The former comes with a
benefit which is especially relevant on 32-bit systems: since
.determine_rate uses an "unsigned long" (compared to a "signed long"
which is used by .round_rate) the maximum value on 32-bit systems
increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz).
Switch to a .determine_rate implementation by default so 32-bit systems
can benefit from the increased maximum value as well as so we have one
fewer user of .round_rate.

These are useful when running on 32-bit systems to increase the upper
supported frequency limit. clk_ops.round_rate returns a signed long
which limits the maximum rate on 32-bit systems to 2^31 (or approx.
2.14GHz). clk_ops.determine_rate internally uses an unsigned long so
the maximum rate on 32-bit systems is 2^32 or approx. 4.29GHz.
To avoid code-duplication switch over divider_{ro_,}round_rate_parent
to use the new divider_{ro_,}determine_rate functions.

Merge tag 'for-linus-5.14-1' of git://github.com/cminyard/linux-ipmi
Pull IPMI driver updates from Corey Minyard:
"Mostly a restructure of the kcs_bmc driver to make it easier to use
with different types of devices, and just to clean things up and
improve things.
Also some bug fixes for the kcs_bmc driver.
One fix to the IPMI watchdog to stop the timer when the action is
none. Not a big deal, but it's the right thing to do"

The Dell Vostro 3350 ACPI video-bus device reports spurious
ACPI_VIDEO_NOTIFY_CYCLE events resulting in spurious KEY_SWITCHVIDEOMODE
events being reported to userspace (and causing trouble there).
Add a quirk setting the report_key_events mask to
REPORT_BRIGHTNESS_KEY_EVENTS so that the ACPI_VIDEO_NOTIFY_CYCLE
events will be ignored, while still reporting brightness up/down
hotkey-presses to userspace normally.

Commit e3c0623608 ("cpufreq: add cpufreq_driver_resolve_freq()")
introduced this callback, back in 2016, for drivers that provide the
->target() callback.
The kernel hasn't seen a single user of it in the past 5 years and
it is not likely to be used any time soon.

Until pwmchip_remove() returns the PWM is supposed to work, so
pwmchip_remove() must be called before the clock is stopped.
The return value of pwmchip_remove doesn't need to be checked because
it returns zero anyhow and I plan to make it return void soon.

vt8500_pwm_remove() is only called after vt8500_pwm_probe() returned
successfully. In this case driver data was set to a non-NULL value
and so chip can never be NULL.

The driver is supposed to stay functional until pwmchip_remove()
returns. So the reset must be asserted only after that.
pwmchip_remove() always returns 0, so the return code can be ignored
which keeps the tegra_pwm_remove() a bit simpler.

There is no reason to enable the PWM clock just to assert the reset
control. (If the reset control depends on the clock this is a bug and
probably it doesn't because in .probe() the reset is deasserted without
the clock being enabled.)

A consumer is expected to disable a PWM before calling pwm_put(). And if
they didn't there is hopefully a good reason (or the consumer needs
fixing). Also if disabling an enabled PWM was the right thing to do,
this should better be done in the framework instead of in each low level
driver.
So drop the hardware modification from the .remove() callback.

tegra_pwm_remove() is only called after tegra_pwm_probe() successfully
completed. In this case platform_set_drvdata() was called with a
non-NULL value and so platform_get_drvdata(pdev) cannot return NULL.
Returning an error code from a platform_driver's remove function is
ignored anyway, so it's a good thing this exit path is gone.
