3a93f2a9f4 regulator: Report actual configured voltage to set_voltage()
Change the interface used by set_voltage() to report the selected value
to the regulator core in terms of a selector used by list_voltage().
This allows the regulator core to know the voltage that was chosen
without having to do an explict get_voltage(), which would be much more
expensive as it will generally access hardware.

495353a3f7 regulator: keep index within bounds in da9034_get_ldo12_voltage()
If selector equals ARRAY_SIZE(da9034_ldo12_data), that is one too
large already.

656d0498ea regulator: fix calculation of voltage range in da9034_set_ldo12_voltage()
For val to be greater than 7 or less than 20 is logically always true.

e88267e164 regulator: replace ADTV1 register by ADTV2 in da903x
In PXA3xx SoC family, V_CORE power doamin is supplied by BUCK1 that is
controller by ADTV1 or ADTV2 register.

By default, v1 and v2 has the same copy. If v1 or v2 is updated, the last
value that is written to either register takes effect. It means that v1
and v2 has different copy. And the actual voltage output is determinated
by last update on either register.

DA9034/35 is binded with PXA3xx SoC family. While SoC is scaling OP or
entering/exiting lower power mode, SoC needs to change voltage of V_CORE
power doamin. In order to be efficient, POWER I2C (hardcode) mode could
be enabled in SoC. In this mode, SoC will control v2 register directly.

In original DA903x driver, software will only read regulator data from v1
register. But SoC controls v2 register directly. It results that v1 and v2
isn't synchronized. Wrong data will be read from v1 register. So access v2
register in da903x driver instead.

5a1b22beef regulator: Move regulator drivers to subsys_initcall()
Regulators need to be available early in init in order to allow them
to be available for consumers when requested. This is generally done
by registering them at subsys_initcall() time but not all regulator
drivers have done that. Convert these drivers to do so in order to
mimimise future support.

0527100fd1 regulator: Pass regulator init data as explict argument when registering
Rather than having the regulator init data read from the platform_data
member of the struct device that is registered for the regulator make
the init data an explict argument passed in when registering. This
allows drivers to use the platform data for their own purposes if they
wish.

1841c0f2bf regulator: da903x regulator bug fix
Changes the device registration part of the probe function to supply the
regulator device rather than its parent (the mfd device) as this caused
problems when the regulator core attempted to find constraints associated
with the regulators.
