Please order alphabetically here.

The accelerometer is not in the camera module like some of our other 
products, but on the PCBA directly, so I would put it in a different 
section in the pinctrl node.

Can you have it this way too:

rockchip,pins =
         <2 RK_PB4 RK_FUNC_GPIO &pcfg_pull_none>;

so it is consistent with the other ones?

Same remark as for Cobra, I assume we want a pull down here, to keep in 
reset until the driver probe drives the pin to orchestrate the reset?

With all the above changed:
