Please split these up into separate patches.

There is no functional reason to bundle them up.

Any indication that it's a PMIC?

I2C/SPI?

Phandled to ...

Masks?  What masks?

Best to make a link to the header where the flags are defined here.

I'd suggest removing the full stops from all of the lines above.

Just treat them as bullet points like we normally do.
