Hi Dafna,
Thank you for the patch.

tbh, I'm not sure if it is better, since it feels it masks pads.
Also, the isp prefix is not required, since it is already inside rkisp1_isp_formats[].
My opinion is that the name "direction" make sense.
Or maybe some other name that reflects which pads the format applies to, but tbh
I think the current one is fine.
Regards,
Helen
