When a pmic_glink client tries to perform a transaction through
pmic_glink_write API during the time when rpmsg device is being
removed, there is a possibility for client attempting to send
a message after rpmsg device has been marked NULL. Add a
read-write semaphore to ensure multiple glink clients can
still perform transactions in parallel while ensuring rpmsg
device removal cannot be done concurrently with transactions.

Currently, sdam_num is used to read SDAM_INDEX for reading samples
from each SDAM. However, it works well only when 2 SDAMs are used.
If ECM supports more than 2 SDAMs, SDAM_INDEX read for the third
SDAM (and after) would be incorrect. Fix it.

Currently ECM_SEND_IRQ and ECM_WRITE_TO_SDAM offsets in first
SDAM is initialized to 0x03 to enable storing samples in two
SDAMs for ECM. With an additional SDAM for ECM, these registers
should be initialized accordingly. Support this by updating those
registers with a value based on number of SDAMs.

Avg_current is an unsigned 16-bit data and assigning it a negative

doesn't make sense for ECM current measurement. Instead, assign it

When ECM is enabled, disable ECM if display goes blank, and re-enable
ECM once display restores to unblank. This helps in keeping ECM HW
enabled only when display is active.
Meanwhile, update the logic a little bit on calculating the average
current. When any of the accumulated values is invalid, just ignore
the calculation instead of disabling the ECM.

PM8350C PWM PPG does away with the need to directly manage the PBS
triggering via the PBS driver APIs by using a single register write to
an SDAM register instead. A PBS sequence thus triggered should be duly
cleared before next use. The existing scheme is also retained for
backward compatibility with targets that use a single-nvmem scheme.
The new PBS triggering scheme also expects a change in the way the high
and low indices pertaining to the pattern are specified.

On PMICs such as PM8350C, the lookup table containing the pattern data
is stored in a separate nvmem device from the one where the per-channel
data is stored.
Add two separate nvmems to handle this case while maintaining backward
compatibility for those targets that use only a single nvmem device.
Differentiate between the two schemes via an enum.

-EPROBE_DEFER instead of NULL. This causes probe failure of the
