This makes buffers allocated as cached on the CPU to be
coherent with the GPU. With this, the GPU is able to
snoop into the CPU's caches to get the data. If the data
is not present in any of the CPU's caches, it is fetched
from main memory. This avoids the need for CPU cache
maintenance operations in software.

On certain PMICs, PMIC peripheral drivers like haptics need to
read MISC peripheral register. Add support for clients to read
it by using qpnp_misc_read_reg().

Update the config option to "CONFIG_QCOM_TLB_HANDLER" so el1_sync
will call into EL2 TLB fault handler. Default TLB handler in EL1
is changed into a dummy handler.

In case of high load on the system the old timeout (10ms)
is not sufficient for GSI to stop a channel.
This change is to increase GSI stop command to 20ms.

For every __pm_stay_awake call, there must be a
__pm_relax call to ensure there is no stale
wakelock is held. with the current logic
__pm_stay_awake is called whenever wakelock ref
cnt is non-zero and released only when it is 0.
This leads to wakelock being held even when
it is not required. Make a change to acquire
wakelock only when it is not held previously.

This change enables midframe sampling timer which samples
the GPU power stats if the command batch expiry takes longer
than the threshold set by KGSL_GOVERNOR_CALL_INTERVAL. This
will help the use cases where long running command batches
were delaying GPU DCVS decision for increasing the frequency.
