This is a driver to handle SiRFStar GNSS chip power controls,
a device node is created to interact with driver power controls
and exposes set of IOCTLs. These IOCTLs provide mechanisms to
transition of GNSS receiver power state.

The address in the CB's FAR is not sign-extended. With split page tables,
this can cause software page table walk causing warning.
WARNING: CPU: 2 PID: 264 at drivers/iommu/arm-smmu.c:3161 arm_smmu_iova_to_phys+0xfc/0x128

Perform the sign extension in fault handler, as arm_smmu_iova_to_phys()
expects the IOVA to be sign extended.

In rare scenarios when the battery enters/exits JEITA conditions
post termination, the termination workaround restarts thus
resetting the reference values. Improve this handling by
restarting the WA only if the existing WA timer is not running
thus avoiding WA restarts across minor JEITA oscillations.

In current code, kgsl_close_device holds device mutex and calls
last_close in case open_count goes to zero. But as part of
last_close call, device mutex is released intermittently to wait
for active count to go to zero and also for dispatcher idle. This
intermittent release of device mutex opens up a window where a
kgsl_open_device call can go ahead and call first_open. As this
first_open is triggered before last_close could finish it messes
up the complete state machine. To fix this, move decrement of
open_count after last_close to allow any open/close happening when
last_close is in progress to just increment/decrement open_count
without triggering first_open or last_close.

Few functions can be handled directly without having
the gpuid checks. So cleanup these functions to avoid
unnecessary gpuid checks.

There is frequent Ping-Pong effect if only consider max_nr
in core control, so also consider average max_nr which in
many windows, this will make core control more smooth.
