[Freedreno] [PATCH v2 1/3] drm/msm/dp: deinitialize mainlink if link training failed

DP compo phy have to be enable to start link training. When link training failed phy need to be disabled so that next link traning can be proceed smoothly at next plug in. This patch de-initialize mainlink to disable phy if link training failed. This prevent system crash due to

[Freedreno] [PATCH v2 3/3] drm/msm/dp: promote irq_hpd handle to handle link training correctly

Some dongles require link training done at irq_hpd request instead of plugin request. This patch promote irq_hpd handler to handle link training and setup hpd_state correctly. Changes in V2: -- fix Fixes tag text Fixes: fdaf9a5e3c15 ("drm/msm/dp: fixes wrong connection state caused by failure

[Freedreno] [PATCH v2 2/3] drm/msm/dp: skip checking LINK_STATUS_UPDATED bit

Some dongle will not clear LINK_STATUS_UPDATED bit after DPCD read which cause link training failed. This patch just read 6 bytes of DPCD link status from sink and return without checking LINK_STATUS_UPDATED bit. Only 8 bits are used to represent link rate at sinker DPCD. The really link rate is

[Freedreno] [PATCH v2 0/3] fix dp link training failed at irq_hpd request

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

This set is part of a larger effort attempting to clean-up W=1 kernel builds, which are currently overwhelmingly riddled with niggly little warnings. This brings the running total from 5000 (in v5.9) down to 1400! Hopefully not too much more to go now. Lee Jones (40):
