There is a dead loop in kgsl_devfreq_target(), while governor request
to change GPU frequency. In governor 'userspace' mode, If the requested
frequency (set_freq) is more than the configured frequency and max_freq
is also set to more than the configured frequency, then there is a dead
loop while changing target frequency.
Dead loop occurs due to comparing signed integer with unsigned integer.
So, type casting unsigned integer to signed integer will terminate the
loop when loop variable is less than zero.

Currently, there is a possibility of out-of-bound access while
processing data received from user space. The patch adds proper
checks for valid address.

Upon encountering any error, few important registers are being captured
in trace logs in sdhci_dumpregs(). But without capturing exact error,
it would be tough to determine from which point in driver this dumpregs
has called. So capture the error state as well in Trace logs before
calling sdhci_dumpregs(). Also capture power irq related registers in
Trace logs upon any power irq related errors.

Add 1024x600p resolution support in adv7533 DSI-to-HDMI
bridge chip on msm8996 automotive target. This change creates
a new timing parameter for DSI panels along with parameters
like vtotal, htotal, panel-width, panel-height etc.

Memory allocations with GFP_KERNEL flag in clock scaling path might
trigger IO transfer. This can cause deadlock since the claim_host
lock which is needed by mmc driver to perform IO is held by clock
scaling context.
Below is the exact call sequence:
mmc_devfreq_set_target() -> mmc_clk_update_freq () ->
mmc_change_bus_speed() -> mmc_select_hs400() -> mmc_select_bus_width()
-> mmc_get_ext_csd() -> kzalloc(512, GFP_KERNEL) -> try_to_free_pages()
-> evict() -> ext4_evict_inode().
To avoid this scenario, use PF_MEMALLOC flag for clock scaling context
so that it can have access to the more reserves of memory. And since
devfreq workitem would run in different kworker threads, restore to
original flags once done with setting clock frequency.
