Subject: [PATCH v2 10/27] drm/sun4i: Start using layer id in DE2 driver
Date: Fri, 1 Dec 2017 07:05:33 +0100 [thread overview]
Message-ID: <20171201060550.10392-11-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20171201060550.10392-1-jernej.skrabec@siol.net>
Till now, plane selection was hardcoded to first overlay in first UI
channel and layer parameter is unused.
Rename and add parameters to layer functions so they would represent HW
more accurately and start using then.
It turns out that overlays don't fit well in current DRM design, because
they can't be blended together or scaled independetly when they are set
to same channel. Because of that, always use only first overlay in each
channel.
