If MST is enabled, the controller needs MST ACT to be
completed to successfully transition to 'Ready for Video'
state. The driver is sending ACT during the normal flow
when transitioning from link training to stream enable.
But it is not sending ACT, if a link maintenance is
triggered after stream enable. This change adds the ACT
update to the link maintenance call flow.

In split link usecase with single DSI and dual sublink, the
pixel clock rate should be calculated based on effective lanes
rather than cumulative lanes on that DSI PHY. This effective lanes
can be expressed as number of lanes being used per sublink.

The sde_hw_blk was meant to be a generic base object for all
SDE HW blocks, however, it enforces using a common set of ops
which is not practical when blocks have different capabilities.
Since this object was never used as intended and is not doing
anything functional today, remove the dead weight.

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.

After an ESD failure, the PHY lanes and controller can be stuck in
an unknown state. This can result in interrupt storms and watchdog
failures, if these error states are not handled correctly. The following
change implements the below mechanism to avoid failures.
1) Disable error interrupts during an ESD reg read, which are re-enabled once
ESD check is successful.
2) On ESD failure, before turning off LP clocks, reset the PHY lanes and DSI
controller.
3) After the HS clocks are turned off, issue a PHY hard reset.
4) Before enabling/disabling error interrupts, clear the error status registers
as they are not cleared as part of controller reset.

When switching between 2 dongles/adapters it is possible
to have the same resolution with different link configuration.
Even though the pixel clock could be the same on replug, the
vco clock could be different depending on the link
configuration. Since the dp driver only exposes limited clocks
to the clock framework, in this specific scenario, the clock
driver is unable to recognize the change in source clock rate
and ends up skipping the clock reconfiguration.
This change adds support to park the pixel clocks on disable,
thereby forcing a reconfiguration on subsequent replug even
if the pixel clocks are the same.

When sde_crtc_atomic_begin is called before crtc is enabled, all the
color processing features need to be moved from active_list to
dirty_list after sde_cp_crtc_apply_properties(). However, the
ltm_hist_en flag doesn't need to be set to false in this case.
Setting ltm_hist_en to false in this case will result LTM merge_en bit
being cleared incorrectly. This change replaces sde_cp_crtc_suspend()
with a new function that only updates the color processing feature lists
in sde_crtc_atomic_begin().
