Subject: [Intel-gfx] [v12 08/15] drm/i915/display: Enable colorspace programming for LSPCON devices
Date: Fri, 27 Nov 2020 02:33:07 +0530	[thread overview]
Message-ID: <20201126210314.7882-9-uma.shankar@intel.com> (raw)
In-Reply-To: <20201126210314.7882-1-uma.shankar@intel.com>

Enable HDMI Colorspace for LSPCON based devices. Sending Colorimetry
data for HDR using AVI infoframe. LSPCON firmware expects this and though
SOC drives DP, for HDMI panel AVI infoframe is sent to the LSPCON device
which transfers the same to HDMI sink.

v2: Dropped state managed in drm core as per Jani Nikula's suggestion.

v3: Aligned colorimetry handling for lspcon as per compute_avi_infoframes,
as suggested by Ville.

v4: Finally fixed this with Ville's help, re-phrased the commit header
and description.
