Subject: [PATCH v5 34/44] media: sun6i-csi: Introduce format match structure, list and helper
Date: Wed, 25 May 2022 21:06:07 +0200 [thread overview]
Message-ID: <20220525190617.696344-35-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20220525190617.696344-1-paul.kocialkowski@bootlin.com>
Introduce a list of mbus/pixel format combinations that need an exact
match between the two sides. This is the case when using raw input
configuration. The list will be used to replace the
sun6i_csi_is_format_supported combinatory helper.
