Subject: [PATCH 01/10] drm : adds Y-coordinate and Colorimetry Format
Date: Fri, 30 Dec 2016 10:55:15 +0530 [thread overview]
Message-ID: <1483075524-25189-2-git-send-email-vathsala.nagaraju@intel.com> (raw)
In-Reply-To: <1483075524-25189-1-git-send-email-vathsala.nagaraju@intel.com>
PSR2 vsc revision number hb2( as per table 6-11)is updated to
4 or 5 based on Y cordinate and Colorimetry Format as below
04h = 3D stereo + PSR/PSR2 + Y-coordinate.
05h = -3D stereo- + PSR/PSR2 + Y-coordinate + Pixel Encoding/Colorimetry
Format indication. A DP Source device is allowed to indicate the pixel
encoding/colorimetry format to the DP Sink device with VSC SDP only when
the DP Sink device supports it (
i.e.,VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED bit in the
DPRX_FEATURE_ENUMERATION_LIST register (DPCD Address 02210h, bit 3;
is set to 1).
v2: (Jani)
- Change DP_PSR_Y_COORDINATE to DP_PSR2_SU_Y_COORDINATE_REQUIRED.
- Add DP_PSR2_SU_GRANULARITY_REQUIRED.
- Change DPRX_FEATURE_ENUMERATION_LIST to DP_DPRX.
- Add GTC_CAP and AV_SYNC_CAP, other bits in DPRX_FEATURE_ENUMERATION_LIST.
v3: (Jani)
- Add support for bits 7:4 and 1 as per DP v1.4 for
DPRX_FEATURE_ENUMERATION_LIST.
