ARM: dts: msm: add PMIC PWM devices for PMA8084

Add device tree nodes to support the PWM/LPG devices found in
PMA8084 PMIC chips.

Also disable PMA8084 PWM devices for MSM8974Pro-AC targets which
utilize PM8941 chips so that the there are no duplicate PWM
channel ID values.

ASoC: wcd9xxx: Update button release thresholds based on current micbias

During short button press, the button release threshold
registers are updated based on the determined button number
so that when mic voltage goes above the programmed value,
release interrupt will be triggered. This reduces delay in
reporting button release. However, the release thresholds
should be programmed based on the current micbias voltage
instead of programming based on 2.7V micbias. Otherwise,
it is possible that during playback where micbias is switched
to VDDIO (1.8V), the mic voltage would never go beyond the
voltage programmed in release threshold registers there by
not generating release interrupt at all.

power: qpnp-bms: do not adjust when shutdown soc is being applied

When the shutdown SOC is being applied, do not adjust the SOC before
using it for reporting. This is to prevent situations where the SOC can
be adjusted upwards when discharging, or adjusted downwards when
charging, but before the monotonic filtering can apply.

This change will ensure SoC monotonicity during discharge across power
cycles.

power: qpnp-bms: fix coulomb counter selection

There is a bug in the BMS code right now where reading the coulomb
counter actually reads the shadow coulomb counter and vice versa. Fix
this by correctly specifying the coulomb counter to be read.

i2c_qup: Fix for unhandled IRQ

I2C qup driver handle scenario where runtime
PM is not enabled and enables clocks explicitly.
But it checks runtime PM suspended state in ISR
routine before processing further which can lead to issue
of unhandled valid IRQ sometimes because I2C client
can initiate transaction very early after system
resume and runtime PM is not enabled.

Add atomic flag to synchronize between active transaction
request when clocks are enabled and ISR.

leds: leds-qpnp: provide pwm period when leds are set to LPG mode in DT

In the current design, if MPP-controlled leds or RGB leds are configured
to LPG mode in the device tree, the PWM period value is not provided.
This will result in "pwm_cfg->pwm_period_us" being assigned to zero
since no PWM period value will be read from device tree. As a result,
qpnp_pwm_init() returns error, which in turn results in failure of
qpnp_mpp_init() or qpnp_rgb_init() and finally resulting in failure of
qpnp_leds_probe().

So "qcom,pwm-us" property should be provided in DT for the above case and
the property parsing needs to be implemented in the leds-qpnp driver.

USB: android: release spinlock before queuing work in android_setup

In android_setup we release spinlock after scheduling the work but there
is no need for holding the spinlock during the schedule_work call
is executed this can lead to spinlock timeouts in case where schedule
work takes more time.

So before scheduling work in android_setup we release spinlock to avoid
potential spinlock lockup or timeout.

msm_serial_hs: Fix the logic for numbering the serial device

This patch fixes the way the UART nodes are enumerated when
aliases are used to identify the nodes. The atomic variable that
used to hold the next available node number was incorrectly being
incremented and if that number were to hold a number that was also
used in an alias, the probe would fail. This patch corrects it.
It also removes the atomic variable and introduces two apis to set
and get the next device number and this logic is protected by a mutex.
