maybe "is a power efficient" instead of "the first" ;-)

I don't think we want to hard-code linux bootargs in the generic devicetree

As Rob noted in the px30 evb patch, there is now a property helping
to drop these long lists of brightness levels, see

The mp8859 seems to be an i2c-device, as also shown by the
nearly empty mp8859 entry below, so shouldn't this regulator
be defined there?

vsel-gpios is not defined in the mainline dt-binding of the fan5355/syr82*

missing a dt-binding and also a real regulator implementation?

mainline binding expects an "interrupts" property not the
fcs,int-n from above

sound-dai-cells are in rk3399.dtsi now ... see

the extcon is not described in the mainline fusb302 binding.

don't leave commented stuff in the dt please.
