Paul Hsieh bd4905a958 drm/amd/display: Add retry to read ddc_clock pin ... [WHY] On customer board, there is one pluse (1v , < 1ms) on DDC_CLK pin when plug / unplug DP cable. Driver will read it and config DP to HDMI/DVI dongle. [HOW] If there is a real dongle, DDC_CLK should be always pull high. Try to read again to recovery this special case. Retry times = 3. Need additional 3ms to detect DP passive dongle(3 failures) Signed-off-by: Paul Hsieh <paul.hsieh@amd.com> Reviewed-by: Eric Yang <eric.yang2@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>		2018-12-18 18:25:12 -05:00
