Series [v4,1/8] media: dt-bindings: Add OV5670 | expand

Commit Message

Jacopo Mondi Jan. 25, 2023, 5:37 p.m. UTC 
Implement the .init_cfg() pad operation and initialize the default
format with the default full resolution mode 2592x1944.

With .init_cfg() pad operation implemented the deprecated .open()
internal operation can now be dropped.
