This leads to confusion of what charging enabled really means.
POWER_SUPPLY_PROP_BATTERY_CHARGING_ENABLED was introduced to indicate
enabling the charge path, and in this case
POWER_SUPPLY_PROP_CHARGING_ENABLED is used to indicate enabling the
input path. Since these are similarly named it leads to even more
confusion.
In an attempt to fix this confusion we introduce a new power supply
property POWER_SUPPLY_PROP_INPUT_SUSPEND which indicates suspending the
input path of the power supply. POWER_SUPPLY_PROP_CHARGING_ENABLED takes
its original definition of enabling the charge path. Then
POWER_SUPPLY_PROP_BATTERY_CHARGING_ENABLED will be retired from use.

slim: msm: ngd: Add priority to DSP SSR notifier
Currently SSR framework seems to make callbacks in the order
they were registered, or based on pririties.
Due to this, APR's callback (done in its probe) may be executed
before slimbus driver's callback (only registered after children
are probed). This still works, but may take longer since codec
may try sending some disconnection commands over slimbus if APR
is notified about SSR before codec was notified by slimbus.
This failure may result in some delay in SSR handling which is
more than the KPI numbers expected for this recovery mechanism.
Priority is added to slimbus SSR notifier registration to make
sure its callback is called before APR's.

For the targets with the LMH DCVSh mitigation, HLOS boot-up
mitigation is not required. So make the devicetree properties
related to boot-up mitigation as optional.

or by modifying the porch values or both. Dynamic fps feature
can by used for hdmi to support different use cases like
matching input stream fps with hdmi out.

workqueue: implement lockup detector
Workqueue stalls can happen from a variety of usage bugs such as
missing WQ_MEM_RECLAIM flag or concurrency managed work item
indefinitely staying RUNNING. These stalls can be extremely difficult
to hunt down because the usual warning mechanisms can't detect
workqueue stalls and the internal state is pretty opaque.
To alleviate the situation, this patch implements workqueue lockup
detector. It periodically monitors all worker_pools periodically and,
if any pool failed to make forward progress longer than the threshold
duration, triggers warning and dumps workqueue state as follows.
BUG: workqueue lockup - pool cpus=0 node=0 flags=0x0 nice=0 stuck for 31s!
Showing busy workqueues and worker pools:
workqueue events: flags=0x0
pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=17/256

workqueue cgroup_pidlist_destroy: flags=0x0
pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=1/1
pending: cgroup_pidlist_destroy_work_fn
...
The detection mechanism is controller through kernel parameter
workqueue.watchdog_thresh and can be updated at runtime through the
sysfs module parameter file.
v2: Decoupled from softlockup control knobs.
