[v11,3/5] media: i2c: imx334: support lower bandwidth mode
Commit Message
From: Shravan Chippa <shravan.chippa@microchip.com>
Some platforms may not be capable of supporting the bandwidth
required for 12 bit or 3840x2160@60 resolutions.
Add support for dynamically selecting 10 bit and 1920x1080@30
resolutions while leaving the existing configuration as default.

Now that there are multiple modes supported, this would appear to get the
width, height as well as the other fields (apart from mbus code) from the
first mode.

Is this statement supposed to be a request to change something, or just
a throwaway comment? It's a little hard for me to understand your
intention here, sorry.
