[PATCH v2 1/6] media: ov5647: Add set_fmt and get_fmt calls.

From: Roman Kovalivskyi
Date: Mon May 18 2020 - 21:16:54 EST


From: Dave Stevenson <dave.stevenson@xxxxxxxxxxxxxxx>

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.
