[PATCH 1/2] drm: Add a detailed DP HDMI branch info on debugfs

[PATCH 1/2] drm: Add a detailed DP HDMI branch info on debugfs

[Gwan-gyeong Mun]

When DP downstream has HDMI branch, it checks below functionality and
shows supports. It follows DP 1.4a spec; Table 2-161: Address Mapping
within DPCD Receiver Capability Field (DPCD Addresses 00000h
through 000FFh).

Added flags for DP downstream:
YCBCR422_PASS_THROUGH_SUPPORT, YCBCR420_PASS_THROUGH_SUPPORT,
CONVERSION_FROM_YCBCR444_TO_YCBCR422_SUPPORT and
CONVERSION_FROM_YCBCR444_TO_YCBCR420_SUPPORT.

[PATCH 2/2] drm/i915/dp: Add checking of YCBCR420 Pass-through to YCBCR420 outputs.

[Gwan-gyeong Mun]

When a DP downstream uses a DP to HDMI active converter, the active
converter needs to support YCbCr420 Pass-through to enable DP YCbCr 4:2:0

This looks a bit incomplete, and should really be in the core. I have a
bunch of stuff for DFPs sitting in a branch. I'll just post the whole
thing...

[PATCH 2/2] drm/i915/dp: Add checking of YCBCR420 Pass-through to YCBCR420 outputs.

[Gwan-gyeong Mun]

When a DP downstream uses a DP to HDMI active converter, the active
converter needs to support YCbCr420 Pass-through to enable DP YCbCr 4:2:0
outputs.
