Add pwm reset support so that for each frame, period and
duty_cycle can be changed dynamically. While at it, also
update the pdm_pwm_free API with PWM disable functionality.

When remoteproc goes down unexpectedly this results in a state where any
acquired hwspinlocks will remain locked possibly resulting in deadlock.
In order to ensure all locks are freed we include a call to
qcom_smem_bust_hwspin_lock_by_host() during remoteproc shutdown.
For qcom_q6v5_pas remoteprocs, each remoteproc has an assigned smem
host_id. Remoteproc can pass this id to smem to try and bust the lock on
remoteproc stop.
This edge case only occurs with q6v5_pas watchdog crashes. The error
fatal case has handling to clear the hwspinlock before the error fatal
interrupt is triggered.

There are cases where the device receives an inbuf msg type related to
an ack and hold on to the buffer without it being reclaimed by the
driver. Add a new msg type, MSG_INBUF_RECLAIM, so the driver can reclaim
inbuf that the device no longer needs.

Incorrect use of spin lock leads to unexpected behavior when trying to
lock between SSR callback and main workqueue. Both SSR callback and main
workqueue calls functions which potentially can sleep within the spin
lock. Switch over to mutex as that is the proper locking mechanism for
these scenario.

Add qcom_smem_bust_hwspin_lock_by_host to enable remoteproc to bust the
hwspin_lock owned by smem. In the event the remoteproc crashes
unexpectedly, the remoteproc driver can invoke this API to try and bust
the hwspin_lock and release the lock if still held by the remoteproc
device.

In the cpuidle-psci case, runtime PM in combination with the generic
PM domain (genpd), may be used when entering/exiting a shared idle
state. More precisely, genpd relies on runtime PM to be enabled for
the attached device (in this case it belongs to a CPU), to properly
manage the reference counting of its PM domain.
This works fine most of the time, but during system suspend in
dpm_suspend_late(), the PM core disables runtime PM for all devices.
Beyond this point, calls to pm_runtime_get_sync() to runtime resume
a device may fail and therefore it could also mess up the reference
counting in genpd.
To fix this problem, let's call wake_up_all_idle_cpus() prior to
disabling runtime PM. In this way a device that belongs to a CPU,
becomes runtime resumed through cpuidle-psci and stays like that
because idle governor will stop selecting deeper idle state when
suspend is started.

Usecases where branch clock will be enabled pre-HLOS and
expectation from the clock provider is to poll on the clock
to ensure it is indeed enabled and not HW gated, thus add

was allocated and assigned to drvdata->buffer, and buf will be
freed because etf can't be enabled, but drvdata->buffer
still point to the address.
So in function tmc_read_unprepare_etb, beacause drvdata->mode
is CS_MODE_DISABLED, local variable buf was assigned by
drvdata->buf and free again.
