use of the recently added mechanism to adapt initialisation values
for such use-cases.

Pass constraint information for recently supported external AB8500

for each of the 3 supported external supplies to low-power, off and
high-power for supply 1, 2 and 3 respectively.

Clean out initialisation that is handled by SoC. Regulator
settings for Vpll (partly), Vsmps1, Vsmps2, Vsmps3 (partly),
Vrf1, Varm, Vape, Vbb, Vmod are cleaned out. They should not
be touched by the kernel.
We also update many of the initialisation values to be more
in-line with the current development efforts of ST-Ericsson
internal engineers.

The ab8500 MFD should not have knowledge about regulator-
specific platform data like number of regulators and
regulator registers. As the regulator platform data is
about to grow with external regulators, this information
is moved to a new structure provided by the regulator
driver.

This patch ensures that many of the recent developments pertaining to
the AB8500 regulator device are propagated out into the public arena.
It aims to update some of the existing initialisation values in

There is already before a register mask in the regulator driver
to allow some bits of a register to be initialized. The register
value is defined in the board configuration. This patch puts a
mask in the board configuration to specify which bits should
actually be altered. The purpose with this patch is to avoid
future mistakes when updating the allowed bits in the regulator
driver.

The SMSC911x Ethernet chip requires a fixed-regulator in order to

that.
