drm/msm/hdmi: rework and fix the HPD even generation
|
expand
|
The MSM HDMI driver is plagued with the long-standing bug. If HDMI cable is disconnected, in most of the cases cable reconnection will not be detected properly. We have been carrying the patch from [1] in our integration tree for ages. The time has come to fix the long-standing bug and implement proper HPD handling. This series was tested on msm8996 and apq8064 boards. Previously HPD handling sometimes could trigger in the CRTC event handling, however I can no longer reproduce it now.
