Merge tag 'regulator-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator 

Pull regulator updates from Mark Brown:
 "This release has lots and lots of small cleanups and fixes in the
  regulator subsystem, mainly cleaning up some bad patterns that got
  duplicated in DT code, but otherwise very little of note outside of
  the scope of the relevant drivers:

   - Support for configuration of the initial state for gpio regulators
     with multi-voltage support.
   - Support for calling regulator_set_voltage() on fixed regulators.
   - New drivers for Broadcom BCM590xx, Freescale pfuze200, Samsung
     S2MPA01 & S2MPS11/4, some PWM controlled regulators found on some
     ST boards and TI TPS65218"

* Samsung S2MPA01 Voltage and Current Regulator
The Samsung S2MPA01 is a multi-function device which includes high
efficiency buck converters including Dual-Phase buck converter, various LDOs,
and an RTC. It is interfaced to the host controller using an I2C interface.
Each sub-block is addressed by the host system using different I2C slave
addresses.
Required properties:
- compatible: Should be "samsung,s2mpa01-pmic".
- reg: Specifies the I2C slave address of the PMIC block. It should be 0x66.
Optional properties:
- interrupt-parent: Specifies the phandle of the interrupt controller to which
the interrupts from s2mpa01 are delivered to.
- interrupts: An interrupt specifier for the sole interrupt generated by the
device.
Optional nodes:
- regulators: The regulators of s2mpa01 that have to be instantiated should be
included in a sub-node named 'regulators'. Regulator nodes and constraints
included in this sub-node use the standard regulator bindings which are
documented elsewhere.
Properties for BUCK regulator nodes:
- regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
(default), 25000, or 50000. May be 0 for disabling the ramp delay on
BUCK{1,2,3,4}.
In the absence of the regulator-ramp-delay property, the default ramp
delay will be used.
NOTE: Some BUCKs share the ramp rate setting i.e. same ramp value will be set
for a particular group of BUCKs. So provide same regulator-ramp-delay=<value>.
The following BUCKs share ramp settings:
* 1 and 6
* 2 and 4
* 8, 9, and 10
The following are the names of the regulators that the s2mpa01 PMIC block
supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of s2mpa01.
- LDOn
- valid values for n are 1 to 26
- Example: LDO1, LD02, LDO26
- BUCKn
- valid values for n are 1 to 10.
- Example: BUCK1, BUCK2, BUCK9
Example:
s2mpa01_pmic@66 {
