LSPCON is a DP->HDMI active dongle, enumerated as DP dual
mode adapter on Intel GEN9 platforms. It's provided by two
different vendors
- Mega Chips America (MCA)
- Parade Technologies (Parade)
In order to support YCBCR 4:2:0 outputs, these are the essential
steps:
- Convert HDMI output format from RGB to YCBCR 4:4:4.
- Set appropriate color space in AVI infoframes.
- Write AVI infoframes to vendor specific AUX registers.
This patch series adds 5 patches, to accommodate above steps and
enable YCBCR 4:2:0 output for LSPCON based HDMI displays. As this
series is dependent on HDMI 2.0 YCBCR 4:2:0 framework, it also
contains 15 patches from HDMI 2.0 YCBCR 4:2:0 series too, which are
published and reviewed as a separate series here:
https://patchwork.freedesktop.org/series/26973/
Requesting reviewers to review only last 5 patches, starting from
patch 15, which are:
drm: add function to read vendor OUI
drm/i915: check LSPCON vendor OUI
drm/i915: YCBCR 420 support for LSPCON
drm/i915: Move AVI infoframe function to DDI layer
drm/i915: write AVI infoframes for LSPCON
