drm/amd/display: fix YCbCr420 blank color

[ Upstream commit 12750d1647f118496f1da727146f255f5e44d500 ] [Why] YCbCr420 packing format uses two chanels for luma, and 1 channel for both chroma component. Our previous implementation did not account for this and results in every other pixel having very high luma value, showing greyish color instead of black. YCbCr444 = ; ..... YCbCr420 = ; .....

drm/amd/display: Disable 4k 60 HDMI on DCE11

2018-10-25T01:04:18Z

[Why] Carrizo and Stoney have severe corruption when trying to power 4k 60 monitors over HDMI connectors that support 4k 60. Carrizo and Stoney require retimers and redrivers to support 4k 60 over HDMI. This driver does not currently support these. Thus, 4k 60 HDMI (and all other modes requiring over 300MHz) should be disabled. [How] Reduce the dce11 HDMI pixel clock cap to 300000kHz.

drm/amd/display: Fix Vega10 lightup on S3 resume

2018-09-27T15:03:12Z

[Why] There have been a few reports of Vega10 display remaining blank after S3 resume. The regression is caused by workaround for mode change on Vega10 - skip set_bandwidth if stream count is 0. As a result we skipped dispclk reset on suspend, thus on resume we may skip the clock update assuming it hasn't been changed. On some systems it causes display blank or 'out of range'. [How] Revert "drm/amd/display: Fix Vega10 black screen after mode change" Verified that it hadn't cause mode change regression.
