[PATCH 1/1] media: i2c: imx355: Parse and register properties

[Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx>]

From: Robert Mader <robert.mader@xxxxxxxxxxxxx>

Analogous to e.g. the imx219 driver. This enables propagating the
V4L2_CID_CAMERA_SENSOR_ROTATION and V4L2_CID_CAMERA_ORIENTATION
values so that userspace - e.g. libcamera - can detect the
correct rotation and orientation from the device tree.
