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.
