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

Hi Jacopo,

thanks for the quick review!

Should I send a v2 for that (adding V4L2_CID_CAMERA_ORIENTATION and your RB to the commit message) - and if so should I first wait for more reviews or is that unnecessary/unlike to happen?

Regards,

Robert

Analogous to e.g. the imx219. This enables propagating
V4L2_CID_CAMERA_SENSOR_ROTATION values so that libcamera
and V4L2_CID_CAMERA_ORIENTATION

can detect the correct rotation from the device tree
and propagate it further to e.g. Pipewire.
Well, yes, that's a consequence. As long as Linux is concerned, this
serves to register the two above mentioned controls.
