c6092f3e66 disp: msm: sde: log intf framecount in event logs
Log hardware interface framecount during te and vblank irqs for
command and video mode panels, respectively. This will help in
debugging any missed frames.

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.

1e3d105dc0 disp: msm: sde: log pp-line count in event logs
Log ping-pong current line count during ctl-start
and rd-ptr interrupt. This will help in debugging
ping-pong timeout issues.
