Subject: [PATCH 05/10] drm/sun4i: Explicitly list and check formats supported by the frontend
Date: Wed, 21 Mar 2018 16:28:59 +0100 [thread overview]
Message-ID: <20180321152904.22411-6-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20180321152904.22411-1-paul.kocialkowski@bootlin.com>
In order to check whether the frontend supports a specific format, an
explicit list and a related helper are introduced.
They are then used to determine whether the frontend can actually support
the requested format when it was selected to be used.
