During scheduler boost the sched_task_load ftrace event might not log
the correct flag value. Ensure that the flag is always initialized with
the selected cluster information.

Revert commit 238f87868d ("soc: qcom: Listen to
SUBSYS_AFTER_SHUTDOWN notification").
SUBSYS_AFTER_SHUTDOWN notification is late for subsystem as they
are not able to communicate with firmware.

Add support for Lpass PIL which facilitates the loading of Lpass
firmware, authentication and bringing it out of reset.

suspend otherwise the clock vote will bump up the ahb

Acquire lock before you check if the service exist. This leads to
race condition where you end up adding same service multiple times
in service_list and make multiple registration request to servreg.

Allow for changing the switching frequency via a power supply property.
The main charger will call this property to ensure optimal power
dissipation.

Modern battery chargers use a switching buck whose frequency
can be adjusted. Create a property to read/update it.

There is a possibility where the driver fails to change
the usb type to Unknown when the cable is removed - in particular
when pd is not allowed.
Use the debounce done event of the typec change interrupt to update
the usb type to Unknown.

Currently the driver uses the dev_ variants to print debug information.
This is not useful.
Instead print the function name and use pr_ variants to print debug
information.

If an HVDCP charger is detected and it does not support PD, that means
it is likely a legacy QC2 or QC3 charger. Rerun APSD when PD sets us to
be inactive.
For cases when pd is not allowed, PD won't set inactive status. For such
cases use the hvdcp_timeout interrupt to rerun APSD.

Add support to set current limits from usb and pd.
Ensure that the limit from the pd is only enforced when pd is active
and that the limit from usb is enforced only when pd is inactive.
There is one situation when the input needs to be suspended as
per the usb driver's request when pd sets system_suspend_supported.
For that allow the usb voter to set that low current value to
suspend.
Also ensure that the pd and usb votes are nullified when source
is removed.
In addition, the return the individual valid votes from usb and pd
when their current_max are read.

The current driver votes and unvotes for removal/insertion at
two interrupt handlers, debounce done and the type C detach.
The recommendation from hw teams is to use debounce done for both
insertion and removal. Update the code.
While at it, provide clean functions to vote and unvote for four
situations
a typec cable insertion
a typec cable removal
a source insertion
a source removal
Note that this allows us to cleanly handle PD hard resets where
the typec connection remains intact but the source (or vbus) related
state needs to be reset.
This also helps us in cleanly handling power sole swaps where the source
plugged and removed functions handle vbus related states while typec
functions handle the typec related states.

There could be cables where vbus and cc lines are shorted or connected
using a small resistor. Raising VBUS to higher values could cause CC
line to get damaged. CC line cannot tolerate a voltage higher than 6V.
So if such a cable is seen, prevent pd stack from running so there is no
opportunity to increase vbus by selecting a higher voltage profile. Also
disable HVDP too.
Also, prevent PD_ALLOWED if a legacy cable is seen - the spec mentions
that if VBUS is seen along with CC, the adapter is not pd capable.
