Subject: [PATCH v6 31/43] media: sun6i-csi: Introduce capture format structure, list and helper
Date: Fri, 26 Aug 2022 20:32:28 +0200 [thread overview]
Message-ID: <20220826183240.604834-32-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20220826183240.604834-1-paul.kocialkowski@bootlin.com>
Add a table that describes each pixel format and associated output
register configuration with necessary tweaks. It will be used later on
to configure the hardware.
