While "fixedregulator" is a seemingly good name, you're not allows to
use a unit address on the node if there's no address information in the
node. So you need to give these nodes a non-generic name.


And please move nodes without a reg (i.e. not on an mmio bus) out of
/soc, i.e. place it near /chosen.

Please ensure that cci and camss have labels and reference them by &cci
and &camss below the / {}, sorted by label name.

Please reference this by its label as well.

This comment gives me the feeling that this node should have been status
disabled, please confirm.
