input: misc: akm8975: fix kernel panic on shutdown
When device is full flashed then reboots, sometimes akm_probe() and
akm_shutdown() races. akm_shutdown() release all the resources thus kernel
panic can occur in akm_probe().

On Tegra T11x WDT FIQ is not routed to the GIC, so we cannot use Tegra
WDT for soft-hang debugging.
This WAR is to configure GIC group0 to generate the FIQ to CPU, and only
let WDT routed to GIC group0. All other normal IRQs will use GIC group1.
This WAR is only applicable to non-secure OS build; secure OS build will
treat FIQ as secure interrupt for enterring monitor.
This patch is based on previous work of Lucas Dai and Bo Yan.
The FIQ WAR requires all the IRQs using the GIC group1, and let the FIQ
use GIC group0 only. This patch will set all the normal IRQs to group1
if GIC WAR is enabled.
- there is below race condition in cec driver :
-tegra_cec_init() is in progress which is setting many registers
-suspend is called at the same time
-tegra_cec_suspend() disables clock before tegra_cec_init() completes
- above race condition hangs the system with trying to write cec
register while clock is off
- fix this race condition by deferring suspend if init is still in
progress
Need to handle retune request case also in the tuning procedure.
We set retune flag if we remove (un-plug) SD card.
So, tuning should be done next time when SD card is inserted.
Continue tuning procedure for full window calculation,
for the full window size is greater or equal to 50% of
partial window size, else choose partial window.

This version fixes the corruption of secure os(TF) stack which is caused by
unexpected hardware cache activities at the time of core #0 wakes up from
per-core power gating.
Caches ON while go to sleep and L1 cache is all cleaned before the sleep,
while L2 cache is selectively cleaned because it's preserved during
the sleep of the cores so L2 cache has some dirty lines from the secure world.
When core #0 wakes up, it turns on i-, d-caches but MMU is still off at this
moment. During this time the wake up process starts synching (flushing) cache
to SDRAM. Until MMU is ON, core #0 uses stacks data from SDRAM, not from the
data cache. It is enough to flush the old line of stack to SDRAM in order to
corrupt call-return linkage if it accidently happens during such stack usage.
To fix this issue, TF cleans the cache lines related to secure os stack
after they have been used last time just before returning to normal OS.
This patch enables the GPIOs and IRQ for the Pike module on
Dalmore. If the pike module is detected, it is enabled instead
of the camera and the motion sensors.
Predict millivolts interface selected pll or dfll mode tables based
on target rate and dynamic dvfs state: rail mode, and current dvfs
clock rate. Since interface clients may not be serialized with run
time rate/voltage scaling (e.g., edp client) it opens possibility for
races. On the other hand there is no need to use current dynamically
changes state to select scaling table - comparing target rate, with
initialized once dfll rate range is sufficient. This commit updated
predict millivolts interface accordingly.
TCTRL/RCTRL values can be calculated either using xusb PADCTL registers
or using SNPS registers. As per latest discussion with HW team, we must
use SNPS registers when any of UTMIP port is owned by SNPS controller and
use XUSB PADCTL registers only when all UTMIP ports are owned by XUSB.
TCTRL/RCTRL is alwasy needed to be programmed on T114 due to a HW bug but
on T124 it needs to be programmed only during ELPG entry when PMC is being
ARMed. Refer table below on this.
T114 T124
1) Init Yes No
2) ELPG entry Yes Yes
3) LP0 exit Yes No
rel-17 branch doesn't have T124 related changes so only T114 relevant changes
are added here.
