Subject: media: i2c: imx355: Parse and register properties
Author:  Robert Mader <robert.ma...@collabora.com>
Date:    Sun Aug 11 13:17:04 2024 +0200

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.
