You need to create a new regulator of some kind and then provide a way
for machines to set the supply_regulator in the init_data.

Yes, and the example code I've deleted all looks about right.

The supply name shold be supplied by the board - it's whatever the
supply that's shared by all the regulators in the OMAP is.

You don't need to specify a supply to hook the supplies up. This is a
bit of a wart, but it's the current API - it's specified in the child
regulator rather than the parent which is the other way around to
consumers.
