drm/amd/display: Revise Sink device string ID

2022-09-19T19:16:26Z

[Why] The Sink device string ID1/ID2 use 5 bytes instead of 6 bytes, so the driver should compare the first 5 bytes only. Reviewed-by: Anthony Koo Acked-by: Wayne Lin Signed-off-by: Robin Chen Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Change AUX NACK behavior

2022-08-25T17:34:40Z

[Why] Retrying on receiving a NACK can result in long overall EDID read times in some cases. [How] Retry only on DEFER and return immediately on NACK. Reviewed-by: Aric Cyr Acked-by: Brian Chang Signed-off-by: Ilya Bakoulin Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Fix pixel clock programming

2022-08-16T22:07:21Z

[Why] Some pixel clock values could cause HDMI TMDS SSCPs to be misaligned between different HDMI lanes when using YCbCr420 10-bit pixel format. BIOS functions for transmitter/encoder control take pixel clock in kHz increments, whereas the function for setting the pixel clock is in 100Hz increments. Setting pixel clock to a value that is not on a kHz boundary will cause the issue. [How] Round pixel clock down to nearest kHz in 10/12-bpc cases.
