Some dongle require link training be done at irq_hpd request. This serial
patches address the issues so that DP/HDMI display can be lit up properlly.
This serial Patch also fixes clock stuck at "off" state error caused by
previous link training failed.

Kuogee Hsieh (3):
  drm/msm/dp: deinitialize mainlink if link training failed
  drm/msm/dp: skip checking LINK_STATUS_UPDATED bit
  drm/msm/dp: promote irq_hpd handle to handle link training correctly
