This patch series adds DRM layer support for YCBCR HDMI output handling. The target HDMI YCBCR outputs are: - YCBCR444 - YCBCR422 - YCBCR420
As YCBCR420 output is added in HDMI 2.0, this patch series also contain few patches to handle new EDID extention blocks, added for YCBCR420 modes (CEA-861-F)
First two patches, complete the CEA modedb in drm driver, by adding new 4k modes. Current CEA modedb contains 64 modes only (VIC 1-64), whereas YCBCR420 output can support 4k modes, from VIC range 93-107. First patch makes sure that it doesn't break existing HDMI 1.4 monitors, adding new VICs.
Next 3 patches, parse and accomodate YCBCR420 suppor information from the sink, and stores into display info strucure. This contains parsing YCBCR420 supported modes, and deep color information.
Next 2 patch create a property (hdmi_output) using which, as userspace can set its preferred HDMI output from RGB, YCBCR444/422/420 etc. Default value of the property is set to RGB(0) so that it doesnt affect existing implementations. Other patch takes care of setting AVI IF colorspace as per the selected output.
Last 3 patches contain implementation of YCBCR output in I915 HDMI subsystem.
V2: - V1 of this patch series was handling both VDB(YCBCR420 only) and VCB (YCBCR420 also) EDID blocks to extract YCBCR420 modes. This series handles only VCB blocks, a follow up series will handle VDB blocks.
This series is tested on Intel GLK platform, using ASTRO-VA-1844A HDMI tester.
