e29493c71d disp: msm: avoid using #ifdef for configurations
Use #if IS_ENABLED() instead of #ifdef for configurations as vendor module
guidelines.

Use #if IS_ENABLED(CONFIG_XXX) instead of #ifdef CONFIG_XXX to ensure that
the code inside the #if block continues to compile if the config changes
to a tristate config in the future.

The differences are as follows:
	1.#if IS_ENABLED(CONFIG_XXX) evaluates to true when CONFIG_XXX is set to
		module (=m) or built-in (=y).
	2.#ifdef CONFIG_XXX evaluates to true when CONFIG_XXX is set to
		built-in(=y) , but doesn't when CONFIG_XXX is set to module(=m).
		Use this only when you're certain you want to do the same thing
		when the config is set to module or is disabled.

8b01e6124e disp: msm: sde: reset mixers in crtc when ctl datapath switches
This change reinitializes the sde_crtc->mixers when CTL
datapath switch occurs during mode set and RM allocation
of CTL hw block is changed. This initialization is required
for CTL_LAYER programming to trigger on the new CTL allocated
from RM.

Issue case:
1. Primary Display is using CTL_0 and it is reserved.
2. Secondary Display is using CTL_1. On suspend, RM adds
   CTL_1 into the free list.
3. External Display is powered on, RM allocates CTL_1 hw blk.
4. Secondary Display is powered on, RM allocated CTL_2 hw blk.
5. External Display is suspended/unplugged, RM adds CTL_1 into
   the free list.
6. When any mode_set(say fps switch) occurs on secondary, RM
   allocates new resources and CTL_1 is allocated.

sde_crtc->num_mixers is non zero, so all the layer programming
happens on CTL_2, but CTL_1_FLUSH bits are programmed causing
hw timeout issue.

fe83c42f56 disp: msm: sde: add support for mdp vsync timestamp
MDSS.9.0 adds support for mdp vsync based HW timestamps
on top the existing support for panel vsync based timestamps.

This allows us to enable vsync timestamp calculations for all the

which we couldn't support with the existing HW.

This change adds the new HW register support and modifies the
timestamp read logic to use mdp vsync on supporting targets.

39e7775bff disp: msm: sde: add support for CTL done irq
From Kalama, the HW scheduler abstracts the low level
PP_DONE/WB_DONE interrupts and generates a common
CTL_DONE interrupt per hw ctl. This saves the software
the irq latency delays to process the frame complete
operations when multiple encoders are involved.

If supported, this change enables and waits for the
CTL_DONE interrupt instead of PP_DONE and WB_DONE.

This change adds support to wait for CTL_DONE irq in
only command mode panels as we don't drive two WB blocks
with single CTL.

35f07ca601 disp: msm: fix rsc static wakeup time calculation
Currently RSC timer register programming is optimized for updating
only during timing param changes and not during RSC state changes
with same timing. Static wakeup time computation should consider
panel jitter for RSC clk state too, else it can result in RSC hang.
This change also removes extra logic for video mode prefil lines
computation for rsc config as video mode does not enable RSC solver.

Current issue scenario exposing the hang is in dual dsi display scenario
where RSC is in clock state and static wakeup time is programmed by
not considering panel jitter, after suspend/pmsuspend while waking up
if RSC switches to command state if primary enabled first and vsync
may arrive much early based on the panel jitter. RSC hw can not handle
if TE arrives earlier than static wakeup time causing RSC hang.

pp_done wait before pre_modeset.
If cur_master is cleared in encoder enable function and irq callback
is triggered at the same time, the irq callback could not be handled
properly as cur_master is NULL.
So remove clearing cur_master in encoder enable function to avoid the
race condition between modeset and irq callback.

a42fd877c7 disp: msm: sde: cancel delayed work items during TUI transition
Delayed work items may touch HW registers. If these work items
run while HW is not owned by this VM it will lead to invalid
access. This happens in video mode as HAL does not disable idle
power-collapse in this mode. It can also happen with ESD status
if lastclose or TUI transition failure occurs.

Although there is a contract with user mode to turn off certain
features, kernel cannot rely on it to always do the right thing.
Prevent potential crashes from certain corner cases by
cancelling all delayed work items when the HW ownership is
transferred.
