[PATCH v2] media: i2c: imx355: Parse and register properties

From: Robert Mader
Date: Sun Aug 11 2024 - 07:18:11 EST


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.
