[PATCH RFC 0/3] ARM: regulator: add Freescale MXS regulator driver

This patch series draft should adds support for Freescale i.MX23, i.MX28
on-chip regulators. I'm new to regulator drivers and need early feedback for
the driver's stage before i go in the wrong direction.

The information about the i.MX28 regulators are from chapter 11 of the
reference manual [1].

This driver based on the Freescale high level [2] and low level driver [3],
but contains the following changes:

* devictree support
* code cleanup

Please bear in mind that the code is not tested against real hardware and
it's not expected to work.

I'm not sure if it's correct, but these series based on the for-next branch
of Mark Brown's regulator repository.

Any comments about the code are welcome.
