When qdss open and close are called back to back at a high rate,
connect_work that gets queued in qdss open can execute after
qdss close. For qdss HW path the connect work that gets scheduled
as part of the next qdss open results in ep config failure as the
ep is already configured during previous connect work. Now before
queuing the request if there is a qdss close it would reset the dbm
ep configuration thus routing this request via software path instead
of dbm path. The subsequent dequeue would lead to a NULL pointer
dereference of completion callback. Fix this by flushing connect_work
as part of qdss close for graceful termination.

During D3hot, we are explicitly blocking L1 state by setting
REQ_EXIT_L1 bit of PM_CTRL register. If we transitioning back to D0
from D3 (without D3cold), REQ_EXIT_L1 bit won't get cleared. And
L1 would get blocked till next D3cold. Clear this explicitly during
D0 to avoid this scenario.

rpmh_rsc_debug() can race with tcs_tx_done() interrupt handler and
may not see any tcs busy and hence won't do bug_on(). Later it may
go ahead and free() the request which interrupt handler is processing.
Lets always bug_on() upon timeout.

This change is to avoid potential race btw stop rx and incoming
SOC RX data in parallel. During suspend path wait_for_transfers_inflight()
logic will check for TX/RX data pending for completion. Check for RX_LEN_IN
status in wait_for_transfers_inflight() and return -EBUSY to avoid race
between stop_rx and SOC RX data.

Currently as part of mmc suspend and resume, we are using
different api's to check support for cmd5 (sleep/awake),
which results in suspend sending cmd5 for sleep, while
in resume it's always going for full init instead of sending
cmd5 for awake. Fix this by using same api in both suspend
and resume paths so that partial init functionality is
actually utilized.

PSI accounts stalls for each cgroup separately and aggregates it at each
level of the hierarchy. This causes additional overhead with psi_avgs_work
being called for each cgroup in the hierarchy. psi_avgs_work has been
highly optimized, however on systems with large number of cgroups the
overhead becomes noticeable.
Systems which use PSI only at the system level could avoid this overhead
if PSI can be configured to skip per-cgroup stall accounting.
Add "cgroup_disable=pressure" kernel command-line option to allow
requesting system-wide only pressure stall accounting. When set, it
keeps system-wide accounting under /proc/pressure/ but skips accounting
for individual cgroups and does not expose PSI nodes in cgroup hierarchy.

The ep_disable functions uses pm_runtime_get_sync &
pm_runtime_put_sync_autosuspend to manage the dev & sysdev,
however doing auto suspend in sync context might lead to
errors on runtime framework due to the ASYNC flag not set.
When this happens, the runtime framework triggers
__might_sleep which in turn leads to a kernel panic.
Fix this by performing pm_runtime_put_autosuspend instead
of doing sync. This will set the ASYNC flag and will not go
for might_sleep check.

Add support for reading ADC channels on a PMIC7 ADC directly from
the ADC_PBS peripheral on that PMIC instead of through PMK8350
ADC peripheral using PBS, for targets where PMK8350 does not run in
master mode.
The conversion request sequence for using ADC_PBS is similar to
the existing one for ADC7, with some differences in register
writes. In addition, SW now performs calibration in place of PBS,
for every conversion, by reading the three calibration channels,
calculating the reference values and entering them in the
calibration registers.

Charger detection can be iio based or psy based or ADSP based. In case
of psy based charger detection POWER_SUPPLY_USB_TYPE_CDP enum is
returned, while in case of iio based charger detection
POWER_SUPPLY_TYPE_USB_CDP enum is returned for cdp detection. Current
case is handling only psy based charger detection i.e driving a pulse
on DP for cdp detection is happening only for psy based charger
detection ensuring proper CDP detection, while failure is seen in
case of iio based cdp charger detection. Hence add support to check
appropriate enum for iio based charger detection as well. To add more
info for ADSP based charger detection driving of dp pulse will be
taken care by adsp.
