From 380d116f08c6ebca53234cba682b7e9e37bbab94 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.org>
Date: Wed, 31 Oct 2018 14:55:37 +0000
Subject: [PATCH] media: ov5647: Add set_fmt and get_fmt calls.
There's no way to query the subdevice for the supported
resolutions.
Add set_fmt and get_fmt implementations.
