Subject: [PATCH 1/3] drm/sun4i: Introduce color encoding and range properties
Date: Sat, 13 Jul 2019 14:03:44 +0200 [thread overview]
Message-ID: <20190713120346.30349-2-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20190713120346.30349-1-jernej.skrabec@siol.net>
In order to correctly convert YUV color space to RGB, we have to know
color encoding and range.
Introduce these two properties using helper method.
