The board compatible needs to be documented.

The earlycon is only needed for debugging early hang issue.  Do you
really want it by default?  If no, we can save the 'bootargs' here,
since 'stdout-path' below will get you correct console setup.

Drop this container node and put fixed regulator directly under root
node.

Please use node name like 'regulator-xxx'.

The 'pinctrl-names' is pointless if there is no 'pinctrl' property.

Drop this container node.

Please name the pinctrl node in a more consistent way, i.e. no
underscore.
