Add Trusted touch support to nt36xxx Touchscreen driver.
This feature enables driver to operate in trusted touch
mode in trusted virtual machine(TVM). The primary virtual
machine(PVM) lends resources such as IO memory and touch
irq to TVM prior to trusted touch is initiated and
reclaims those resources back after trusted touch usecase
finishes. The resource requirements of TVM such as clock,
regulators etc are taken care by PVM. Introduce state
machine for various checkpoints in trusted touch usecase.
In error scenarios, this state machine helps driver to
rollback to previous state.

GENERIC_GETTIMEOFDAY can be enabled only if HAVE_GENERIC_VDSO
is enabled. However, HAVE_ARM_ARCH_TIMER selects it unconditionally,
thus throwing the following warning:
WARNING: unmet direct dependencies detected for GENERIC_GETTIMEOFDAY
Depends on [n]: HAVE_GENERIC_VDSO [=n]
Selected by [y]:
- HAVE_ARM_ARCH_TIMER [=y] && CPU_V7 [=y]
Fix this by selecting GENERIC_GETTIMEOFDAY conditionally in
HAVE_ARM_ARCH_TIMER as well.
Also, handle this conditional dependency in all the references.

The function qcom_scm_mem_protect_region_id dereferences __scm without
checking for NULL and could potentially lead to a NULL pointer exception.
This scenario can happen if the clinet calls qcom_scm_mem_protect_region_id
before qcom_scm driver is even probed. Hence, check for NULL before
dereferencing it.

The device advertises PA_HIBERN8TIME may not be enough for some UFS
devices. To workaround this issue, host should add more 100 us.
The commit 8941234ea1 ("scsi: ufs: Add UFS_DEVICE_QUIRK_PA_HIBER8TIME
quirk") just increase PA_HIBERN8TIME base on TX_HIBERN8TIME_CAPABILITY,
we should increase PA_HIBERN8TIME directly because the
RX_HIBERN8TIME_CAPABILITY may be more than TX_HIBERN8TIME_CAPABILITY.

Add MSS_Q6_BIMC_AXI and MSS_CFG_AHB clocks to GCC for peripheral
clock clients to be able to request for the clocks. While at it, also
add support for debug clock controller to measure frequency of clocks.

to flush touch FIFO since ownership of register space
is with Trusted VM. Additionally add extra regulator
vote before starting TUI.

GSI Driver get the usage count in work handler when set_alt 1 happens
and this counter will decrement in disconnect work due to cable disconnect
or in gsi_suspend for suspended state.
In this case set alt to 0 came for MBIM interface and clear the
data_interface_up flag. After that suspend happens and does not decrement
the counter in gsi_suspend. This causes a mismatch of usage count and
usb not entering to low power mode.
Fix this by checking for USB_PROT_GPS_CTRL instead of data_interface_up.
