Veera Sundaram Sankaran fb54f6e6e7 disp: msm: sde: switch to WD vsync on unexpected panel jitter
Switch to watchdog vsync whenever panel jitter is
identified during frame-transfer on command mode display.
This would allow the HW to finish processing the frame
with watchdog vsync source. Switch back to default vsync
source after the frame-transfer is complete. This would
help in the MDP hang issues in panels that generate TEs
with thresholds greater than the projected jitter.
