ASoC: msm: qdsp6v2: Release IPA mapping

When DSP has a SMMU associated with it, audio driver will allocate
(KVA)kernel virtual address and (IPA)intermediate physical
address.When freeing memory audio driver should release IPA and KVA
mappings. Change fixes the issue where IPA mapping was not released

power: qpnp-charger: wake up upon fast charge after resuming

When state of charge based charge resume happens there is
a delay between enabling charging again in hardware and
the fast charge state being reached. During this time
the system may have gone to suspend and the necessary
information is not conveyed to userspace.

Fix this by enabling the fast charge interrupt as a
wakeup interrupt when the SOC based resume event occurs.
Disable it when within the fast charge interrupt handler.

TTY: msm_smd_tty: Fix simultaneous open/close race condition

smd_tty_close currently has a variable that depends on a race
condition with tty_port_open. This causes a null-pointer dereference
when the same port is simultaneously being opened/closed.

Use data from a static array instead of the variable to eliminate
the race condition.

hwmon: qpnp-adc-current: Add temperature compensation

Add temperature compensation parameters for PM8026 2.1.
Compensate the vbatt voltage for temperature variance above
25degC. Add similar compensation for current compensation.

Also update using the revid api's to check for PMIC revision
instead of using peripheral revision registers. Using
revid PMIC api's makes it easy to follow on what PMIC versions
are the temperature compensation being applied to. Depending
on VADC/IADC revision registers alone may not suffice since
there is no correlation between the individual peripheral
revision and the PMIC number. You could have the same
VADC revision on different PMIC's and to avoid such a scenario
use the PMIC revid.

ARM: dts: msm: Add phandle to read PMIC rev-id

The VADC/IADC peripheral need to read the PMIC type
and revision to apply the corresponding coefficients
for temperature compensation to vbatt and current.
The property is optional since there are few PMIC
VADC/IADC peripherals that don't have temperature
compensation coefficients added and during such
conditions the temprerature compensation is not
applied for those channels.

hwmon: qpnp-adc-current: fix current compensation direction

Currently the current compensation in the IADC driver is using the wrong
polarity. The compensation function is treating the current with the
battery being the source (i.e. discharging is positive and charging is
negative), but the IADC's IBAT readings treat the battery as a sink
(i.e. charging is positive and discharging is negative).

Fix this by reversing the sign of the iadc current readings before doing
compensation.

hwmon: qpnp-adc-current: Fix offset channel selection

On PM8941 depending on the status of the BATFET
the reads on channel 0 for Internal RSENSE go to
channel 5 therefore the offset is performed on that
channel. This is applicable to only to PM8941 and
not on PM8026 and PM8110. Therefore apply the check
for offset channel selection based on the BATFET
status on PM8941 only.

For PM8941 when BATFET is open, the reads on channel 0 for
Internal RSENSE are redirected in HW to channel 0x5:
 EXTRSNS_OFFSET. Recalibrate based on this channel.
