By datasheet the VDD (in-kernel named vcc) range is between 2.3 to 4.3 V.
Usually it's around 2.8 V. Here it matches the avdd2v8_dvp.

This does not match reality, schematic says it's VCC2V8_DVP:

Ahoj,

thanks for spotting this, since I know you have the device, would be too much to ask you to send standalone fix for PP Pro?

I would drop the change from the series.

David

P.S. I noticed I didn't mark this series RFC. Too late.


regards,
o.
