When stop is called for doze mode, there is a race condition
between the stop thread and the retire signal work queue.
Fix race condition by making sure that driver waits for the
retire fence before calling the stop.

Migrate tasks function is used by both hotplug and cpu isolation. During
hotplug all the cpus are stalled (in stop machine) while tasks are being
migrated. However, this is not the case during cpu isolation. A task
that was counted as a pinned thread might have been migrated off the
cpu. Take this into account when checking whether we have completed
moving all tasks off the runqueue.
Also ignore warning about tasks moving off the run-queue for isolation
use case.

Cluster cpu list traversal is not properly protected against removal of
element by a separate thread. Add proper locking to ensure an element
cannot be removed while accessing the list.
In addition ensure we don't end up in a livelock never exiting the loop
due to hotplug continuously moving elements to the end of the list.

There is a current leakage on S5 and LDO XO RF rail during
BT sleep. To prevent the current leakage, L7A/L17A/L25A
should be on during BT sleep. So, change L7A/L17A/L25A LDOs
from pin control version to SW control not to follow HW_EN2.
RFCLK2 has not been turned off during sleep and caused
extra current penalty. For RFCLK2 to follow HW_EN2 pin control,
clk_rf_clk2_pin should be used.

Currently, a flag is set when the empty SOC interrupt fires to
indicate SOC 0 to the users. This is not cleared when the battery
voltage goes up. This needs to be fixed. Remove the flag and use
the realtime status of BATT_SOC peripheral to decide it. To make
that even more robust, validate the battery voltage with the
cutoff voltage. While at it, add a print in the driver's probe to
print the battery SOC and voltage. This will be helpful to debug
different battery charging scenarios.

Add support to do initial configuration for alpha plls and votable
alpha PLLs need to have the fsm mode enabled as part of the
initialization using flag 'SUPPORTS_FSM_MODE'.
Alpha PLLs can support two kinds of input signals, normal and latched.
The normal input is directly passed to the core, while the latched input
requires a latch and acknowledge sequence to be performed for the
changed input to propagate.
Alpha PLLs can support dynamic update with both kind of input signals.
The ones which support this using a latched interface however need to
follow the latch/wait-for-ack sequence to be performed when the rate
changes. Mark these with a new flag 'SUPPORTS_DYNAMIC_UPDATE' to handle
this as part of clk_alpha_pll_set_rate().
PLLs could require post div to be set at runtime, add a vco_data which
could be used for these settings.

A CPU that is isolated needs to have its timers migrated off to
another CPU. If while migrating timers, there is a running
timer, acquiring the timer base lock after marking a CPU as
isolated will ensure that:
1) No more timers can be queued on to the isolated CPU, and
2) A running timer will finish execution on the to-be-isolated
CPU, and so will any just expired timers since they're all
taken off of the CPU's tvec1 in one go while the base lock
is held.
Therefore there is no apparent reason to wait for the expired
timers to finish execution, and isolation can proceed to migrate
non-expired timers even when the expired ones are running
concurrently.
While we're here, also add a delay to the wait-loop inside
migrate_hrtimer_list to allow for store-exclusive fairness
when run_hrtimer is attempting to grab the hrtimer base
lock.

Fd is tunneled using userptr memory type to v4l2 rotator
driver. Fd can assume the same value between multiple qbuf but
with the underlying mapping modified. However, v4l2 assumes that
if userptr of the same value are passed in, the underlying buffer
is the same and will bypass memory mapping callback. This will
cause problem for fd tunneling because the obsolete mapping is
used.
To ensure buffer mapping, add buf_finish callback to clear last
fd value before dequeuing buffer back to user client. This will
force the next queue buffer command to invoke memory mapping callback
since the incoming fd value is different from the reset value.
