From 55ebf12c54a53319d6a890eb499b68565242c3c4 Mon Sep 17 00:00:00 2001 From: Laurentiu Palcu Date: Thu, 7 Nov 2019 15:09:11 +0200 Subject: [PATCH] drm/imx/hdp: add colorspace property iMX8MQ has the ability to adjust the DCSS output pipe gamut and nonlinearity depending on the HDMI connector capability. Userspace can explicitly set this property if it decides, based on EDID parsing, that the sink supports REC.2020 and it wants to switch when it plays HDR10 content. Otherwise, the kernel will use the default settings specified in the HDMI specifications.
