Subject: [PATCH 16/25] media: ov5647: Add support for get_selection()
Date: Tue, 23 Jun 2020 18:49:08 +0200
Message-ID: <20200623164911.45147-1-jacopo@jmondi.org> (raw)
In-Reply-To: <20200623100815.10674-1-jacopo@jmondi.org>

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Support the get_selection() pad operation to report the device
full pixel array size, the currently applied analogue crop rectangle and
the active pixel array dimensions.
