From mboxrd@z Thu Jan 1 00:00:00 1970 From: dkos@cadence.com (Damian Kos) Date: Tue, 3 Jul 2018 11:02:20 +0100 Subject: [PATCH 09/12] drm/dp: add pixel encoding and colorimetry format indicator field in MISC1 In-Reply-To: <1530612152-27555-1-git-send-email-dkos@cadence.com> References: <1530612152-27555-1-git-send-email-dkos@cadence.com> Message-ID: <1530612152-27555-10-git-send-email-dkos@cadence.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Quentin Schulz If DP_TEST_COLOR_FORMAT_RAW_Y_ONLY is set, if MISC0 color format is DP_COLOR_FORMAT_RGB and all other bits are 0, then color format is actually Y-Only. If DP_TEST_COLOR_FORMAT_RAW_Y_ONLY is set, if MISC0 color format is DP_COLOR_FORMAT_YCbCr422, DP_TEST_DYNAMIC_RANGE_CEA is not set and chosen ITU is 601, then color format is actually RAW. If DP_TEST_VSC_SDP is set, then DP_TEST_COLOR_FORMAT_RAW_Y_ONLY, DP_TEST_COLOR_FORMAT, DP_TEST_DYNAMIC_RANGE_CEA, DP_TEST_YCBCR_COEFFICIENTS and DP_TEST_BIT_DEPTH are ignored and we should use VSC SDP for setting the colorimetry. This is used for Y420.
