Subject: [PATCH 00/20] YCBCR 4:2:0 handling for LSPCON
Date: Mon, 10 Jul 2017 16:48:28 +0530	[thread overview]
Message-ID: <1499685528-6926-1-git-send-email-shashank.sharma@intel.com> (raw)

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
