Subject: [PATCH v6 1/3] media: i2c: ov772x: Parse endpoint properties
Date: Thu, 17 Sep 2020 18:42:22 +0100 [thread overview]
Message-ID: <20200917174224.11430-2-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20200917174224.11430-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
Parse endpoint properties using v4l2_fwnode_endpoint_alloc_parse()
to determine the bus type and store it in the driver structure.
Set bus_type to V4L2_MBUS_PARALLEL as it's the only supported one
