Subject: [PATCH 0/3] drm/sun4i: Add support for color encoding and range
Date: Sat, 13 Jul 2019 14:03:43 +0200
Message-ID: <20190713120346.30349-1-jernej.skrabec@siol.net> (raw)

In order to correctly convert image between YUV and RGB, you have to
know color encoding and color range. This patch set adds appropriate
properties and considers them when choosing CSC conversion matrix for
DE2 and DE3.

Note that this is only the half of needed changes when using HDMI output.
DW HDMI bridge driver has to be extended to have a property to select
limited (TVs) or full (PC monitors) range. But that will be done at a
later time.

Please take a look.

Best regards,
Jernej
