c2c470efa9 disp: msm: sde: reserve primary CTL and LM for primary connector
In dual display cases when secondary display is resumed first,
primary CTL and LM is selected for secondary path which leads to
invalid configuration. Changes are made to correct the reservation
to select primary CTL and LM for primary connector and secondary
LM to secondary connector.

4776221d5b disp: msm: sde: fix panel mode check during SUI validations
During SUI validations and transitions, the encoders
are iterated to find the panel-mode. If concurrent
writeback is enabled, it is assumed as video mode.
Add check to consider only the built-in display
panel mode during sui to avoid wrong interpretation.

52855c704a disp: msm: sde: dynamic lm reservation for secondary disp
Primary and secondary displays should have first priority
when reserving lms. Static reservation can potentially block
higher resolutions for the required displays. This patch gets
the layer mixer requirement for primary or secondary display
if available. It reserves those layer mixers dynamically
for the respective display when connector is registered.

6daf1c58e7 disp: msm: sde: use wr_ptr interrupt instead of ctl_start
SDE driver triggers the frame and waits for the
ctl_start interrupt for command mode display. This interrupt
provides confirmation that hardware has picked up the
frame. Retire fence signaling is associated with
this interrupt and it is sent at the rd_ptr interrupt
after ctl_start. Due to lut dma delay, ctl_start interrupt
may be trigger before rd_ptr or after rd_ptr. SW manages
this complexity and handle retire fence for different cases
with 500us threshold logic.

This change replaces the ctl_start interrupt with wr_ptr
interrupt by programming it to trigger at 1st write line
count. This is guaranteed to come every time and it is close
to rd_ptr interrupt. That allows retire fence trigger at
wr_ptr interrupt and simplifies the SW logic. CRTC commit
thread would be held slightly longer with this change
as the wr_ptr is always close to rd_ptr and after
ctl_start.

This snapshot ports changes from 4.14 to 4.19 into
the msm and sde layer. Snapshot was taken as of
commit 0f8fb25421ff ("cnss2: Add device version to
SOC info structure").

56e88a7fdc disp: msm: sde: avoid rc lock deadlock during esd failure
Each mode_set call makes sure that previous frame is triggered
and triggers the esd check if there is pp_timeout. This may
lead to deadlock between crtc commit and event threads. Crtc
commit thread acquires the rc_lock and triggers the flush_thread
API on event_thread. Event thread again tries to acquire the
rc_lock to wait for frame. This can be prevented by avoiding the
pre_kickoff call from esd_failure notification if it is generated
through pp_timeout.

Log ping-pong current line count during ctl-start
and rd-ptr interrupt. This will help in debugging
ping-pong timeout issues.

21edecd3b1 disp: msm: Add support for seamless panel operating mode switch
DSI display may support video mode and command mode both and it may
support transition between these two modes.
This change adds seamless transition between these two modes for DSI
display by avoiding crtc enable/disable and panel power on/off
during modeset.
