Re: [PATCH] drm/msm/dp: stop link training after link training 2 failed

Quoting Kuogee Hsieh (2022-01-04 15:52:07)

Each DP link training contains link training 1 followed by link training 2. There is maximum of 5 retries of DP link training before declared link training failed. It is required to stop link training at end of link training 2 if it is failed so that next link training 1 can start freshly. This patch fixes link compliance test case 4.3.1.13 (Source Device Link Training EQ Fallback Test).
