Subject: [PATCH v2 1/6] media: ov5647: Add set_fmt and get_fmt calls.
Date: Tue, 19 May 2020 04:16:16 +0300 [thread overview]
Message-ID: <8a4c0d157d26251c9916b32866e6a4a91c023ef9.1589850165.git.roman.kovalivskyi@globallogic.com> (raw)
In-Reply-To: <cover.1589847910.git.roman.kovalivskyi@globallogic.com>
In-Reply-To: <cover.1589850165.git.roman.kovalivskyi@globallogic.com>
From: Dave Stevenson <dave.stevenson@raspberrypi.org>
There's no way to query the subdevice for the supported
resolutions. Add set_fmt and get_fmt implementations. Since there's
only one format supported set_fmt does nothing and get returns single
format.
