[PATCH V4] drm: Add support for DP 1.4 Compliance edid corruption test

2019-12-09 Thread Jerry (Fangzhi) Zuo
Unlike DP 1.2 edid corruption test, DP 1.4 requires to calculate real CRC value of the last edid data block, and write it back. Current edid CRC calculates routine adds the last CRC byte, and check if non-zero. This behavior is not accurate; actually, we need to return the actual CRC value when
