Instead of looping over increasing values for the prescaler and testing
if it's big enough, calculate the value using a single division.

stm32_pwm_config() took the duty_cycle and period values with the type
int, however stm32_pwm_apply() passed u64 values there. Expand the
function parameters to u64 to not discard relevant bits and adapt the
calculations to the wider type.

To ensure the calculations won't overflow, check in .probe() the input
clk doesn't run faster than 1 GHz.

While mathematically it's ok to calculate the number of cyles for the
duty cycle as:

	duty_cycles = period_cycles * duty_ns / period_ns

this doesn't always give the right result when doing integer math. This
is best demonstrated using an example: With the input clock running at
208877930 Hz a request for duty_cycle = 383 ns and period = 49996 ns
results in

	period_cycles = clkrate * period_ns / NSEC_PER_SEC = 10443.06098828

Now calculating duty_cycles with the above formula gives:

	duty_cycles = 10443.06098828 * 383 / 49996 = 80.00024719

However with period_cycle truncated to an integer results in:

	duty_cycles = 10443 * 383 / 49996 = 79.99977998239859

So while a value of (a little more than) 80 would be the right result,
only 79 is used here. The problem here is that 14443 is a rounded result
that should better not be used to do further math. So to fix that use
the exact formular similar to how period_cycles is calculated.

Now that a pwm_chip has a dedicated struct device, pwmchip_set_drvdata()

After assigning chip = pwm->chip; the compiler is free to assume that
pwm is non-NULL and so can optimize out the check for pwm against NULL.

While it's probably a programming error to pass a NULL pointer to
pwm_put() this shouldn't be dropped without careful consideration and
wasn't intended.

So assign chip only after the NULL check.

This replaces the formerly dynamically allocated struct device. This
allows to additionally use it to track the lifetime of the struct
pwm_chip. Otherwise the new struct device provides the same sysfs API as
was provided by the dynamic device before.

It's required to not free the memory underlying a requested PWM
while a consumer still has a reference to it. While currently a pwm_chip
doesn't live long enough in all cases, linking the struct pwm to the
pwm_chip results in the right lifetime as soon as the pwmchip is living
long enough. This happens with the following commits.

Note this is a breaking change for all pwm drivers that don't use
pwmchip_alloc().

With the upcoming restructuring having all in a single file simplifies
things a bit. The relevant and somewhat visible changes are:

 - Some dropped prototypes from include/linux/pwm.h that were only
   necessary that core.c has a declaration of the symbols defined in
   sysfs.c. The respective functions are static now.

 - The pwm class now also exists if CONFIG_SYSFS isn't enabled. Having
   CONFIG_SYSFS is not very relevant today, but even without it the
   class and device stuff still provides lifetime tracking.

 - Both files had an initcall, these are merged into a single one now.
   Instead of a big #ifdef block for CONFIG_DEBUG_FS, a single
   if (IS_ENABLED(CONFIG_DEBUG_FS)) is used now. This increases compile
   coverage a bit and is a tad nicer on the eyes.

The code handling the sysfs API uses "child" and "parent" to refer to
the devices corresponding to a struct pwm or a struct pwm_chip
respectively.

Other parts of the pwm core use "parent" to refer to the parent device of
a struct pwm_chip.

So rename "child" to "pwm_dev" and "parent" to "pwmchip_dev" which
better explains the semantic. Also two functions are changed to match
the new names:

        child_to_pwm_export() -> pwmexport_from_dev()
        child_to_pwm_device() -> pwm_from_dev()

(which have the additional advantage to start with "pwm" which gives the
right scope). Additionally introduce a wrapper for dev_get_drvdata() to
convert a pwmchip_dev to the respective pwm_chip.

While the compiler probably optimizes out the pointer dereference, using
the local variable holding the same value also benefits the human
reader. So simplify accordingly. Also move a loop over all capture lines
into the capture if block to group the operations related to capturing

Instead of (arbitrarily?) spliting the per-chip driver data into two

This has the advantage of handling EPROBE_DEFER correctly and being more
compact.

This change also introduces an error message for a few error paths that
lacked an error indicator before. Also sti_pwm_probe_dt() is renamed to
sti_pwm_probe_regmap() to better fit what it actually does.

Instead of of_clk_get_by_name() use devm_clk_get_prepared() which has
several advantages:

 - Combines getting the clock and a call to clk_prepare(). The latter
   can be dropped from sti_pwm_probe() accordingly.
 - Cares for calling clk_put() which is missing in both probe's error
   path and the remove function.
 - Cares for calling clk_unprepare() which can be dropped from the error
   paths and the remove function. (Note that not all error path got this
   right.)

With additionally using devm_pwmchip_add() instead of pwmchip_add() the
remove callback can be dropped completely. With it the last user of
platform_get_drvdata() goes away and so platform_set_drvdata() can be
dropped from the probe function, too.

 "This is a bit on the large side, mostly due to two changes:

     without OBJECT_FILES_NON_STANDARD. This fixes a warning "Unpatched
     return thunk in use. This should not happen!" when running KVM

  Everything else is small bugfixes and selftest changes:

   - Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure
     where KVM would allow userspace to refresh the cache with a bogus
     GPA. The bug has existed for quite some time, but was exposed by a
     new sanity check added in 6.9 (to ensure a cache is either
     GPA-based or HVA-based).

   - Drop an unused param from gfn_to_pfn_cache_invalidate_start() that
     got left behind during a 6.9 cleanup.

   - Fix a math goof in x86's hugepage logic for
     KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow
     (detected by KASAN).

   - Fix a bug where KVM incorrectly clears root_role.direct when
     userspace sets guest CPUID.

   - Fix a dirty logging bug in the where KVM fails to write-protect
     SPTEs used by a nested guest, if KVM is using Page-Modification
     Logging and the nested hypervisor is NOT using EPT.

  x86 PMU:

   - Drop support for virtualizing adaptive PEBS, as KVM's
     implementation is architecturally broken without an obvious/easy
     path forward, and because exposing adaptive PEBS can leak host LBRs
     to the guest, i.e. can leak host kernel addresses to the guest.

   - Set the enable bits for general purpose counters in
     PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD
     processors.

   - Disable LBR virtualization on CPUs that don't support LBR
     callstacks, as KVM unconditionally uses
     PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and
     would fail on such CPUs.

  Tests:

   - Fix a flaw in the max_guest_memory selftest that results in it
     exhausting the supply of ucall structures when run with more than

Pull clk fixes from Stephen Boyd:
 "A couple clk driver fixes, a build fix, and a deadlock fix:

   - Mediatek mt7988 has broken PCIe because the wrong parent is used

   - Mediatek clk drivers may deadlock when registering their clks
     because the clk provider device is repeatedly runtime PM resumed
     and suspended during probe and clk registration.

     Resuming the clk provider device deadlocks with an ABBA deadlock
     due to genpd_lock and the clk prepare_lock. The fix is to keep the
     device runtime resumed while registering clks.

   - Another runtime PM related deadlock, this time with disabling
     unused clks during late init.

     We get an ABBA deadlock where a device is runtime PM resuming (or
     suspending) while the disabling of unused clks is happening in
     parallel. That runtime PM action calls into the clk framework and
     tries to grab the clk prepare_lock while the disabling of unused
     clks holds the prepare_lock and is waiting for that runtime PM
     action to complete.

     The fix is to runtime resume all the clk provider devices before
     grabbing the clk prepare_lock during disable unused.

   - A build fix to provide an empty devm_clk_rate_exclusive_get()
     function when CONFIG_COMMON_CLK=n"
