IPA and GSI firmwares are saved on the file-system as an
ELF file. IPA driver extracts the firmwares and load
them during driver initialization.
This change adds validation steps to each firmware before
loading: load addresses, memory sizes, firmware sizes and
more...

XHCI allows interrupt moderation using imod_interval at 250ns
increments. Add DT parameter to specify this imod_value for
targets mainly with single CPU to reduce CPU interrupt loads.
This allows better balance between CPU usage and performance.

There is no advantage of tracking busy time counters per related
thread group. We need busy time across all groups for either a CPU
or a frequency domain. Hence maintain group busy time counters in
the runqueue itself. When CPU window is rolled over, the group busy
counters are also rolled over. This eliminates the overhead of
individual group's window_start maintenance.
As we are preallocating related thread group now, this patch saves
40 * nr_cpu_ids * (nr_grp - 1) bytes memory.

USB Main charger type represents the main charging path. This will
be used to control charging parameters on the main charger.
FCC_DELTA property will be used to indicate whether hw implements
any FCC mitigation. This will be used to calculate the effective FCC
and set the FCC on the PMI.
PARALLEL_MODE property indicates whether the parallel charger chip is
configured in a mid-mid or usbin-usbin configuration.
ICL_REDUCTION property indicates by how much should the main charger
reduce its input current.

Colocation in HMP includes a tunable that turns on or off the feature
globally across all colocation groups. Supporting this tunable correctly
would result in complexity that would outweigh any foreseeable benefits.
For example, disabling the feature globally would involve deleting all
colocation groups one by one while ensuring no placement decisions are
made during the process.
Remove the tunable. Adding or removing a task from a colocation group is
still possible and so we're not losing functionality.

Since clusters can vary significantly in the power and performance
characteristics, there may be a need to have different CPU selection
policies based on which cluster a task is being placed on. For example
the placement policy can be more aggressive in using idle CPUs on
cluster that are power efficient and less aggressive on clusters
that are geared towards performance. Add support for per cluster
wake_up_idle flag to allow greater flexibility in placement policies.

Commit 0013b23d66 ("leds: disable
triggers on brightness set") removes the trigger on a LED class
device when brightness is set to 0. However, there are some LED
class devices which needs the trigger not to be removed. In an
use case like camera flash, camera flash driver passes in a
trigger device to LED class driver. If the trigger is removed
when the brightness is set to 0, this will affect the clients
using those triggers. Hence add a flag to always keep the trigger
even when brightness is set to 0.
