Merge tag 'regulator-v3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator into next

Pull regulator updates from Mark Brown:
 "The bulk of the changes for this release are a few new drivers however
  there are a couple of noticable core changes and the usual stream of
  cleanups and fixes:

   - move disable of unused regulators later in init so it comes after
     deferred probe has iterated making startup smoother.
   - fixes to reference counting of the DT nodes for constraints from
     Charles Keepax.  This has little practical impact since all real
     users of the regulator bindings use FDT which doesn't need the
     reference counting.
   - lots of cleanups, especially to the Samsung drivers.
   - support for Linear Technologies LTC3589, Texas Instruments
     TPS658640 and X-Powers AXP20x"

On S2MPS14 the LDO10, LDO11 and LDO12 can be configured to external control

over GPIO. To turn this feature on this property must be added to the regulator

sub-node:

Linear Technology LTC3589, LTC3589-1, and LTC3589-2 8-output regulators



Required properties:

- compatible: "lltc,ltc3589", "lltc,ltc3589-1" or "lltc,ltc3589-2"

- reg: I2C slave address



Required child node:

- regulators: Contains eight regulator child nodes sw1, sw2, sw3, bb-out,

  ldo1, ldo2, ldo3, and ldo4, specifying the initialization data as

  documented in Documentation/devicetree/bindings/regulator/regulator.txt.



Each regulator is defined using the standard binding for regulators. The

nodes for sw1, sw2, sw3, bb-out, ldo1, and ldo2 additionally need to specify

the resistor values of their external feedback voltage dividers:



Required properties (not on ldo3, ldo4):

- lltc,fb-voltage-divider: An array of two integers containing the resistor

  values R1 and R2 of the feedback voltage divider in ohms.



Regulators sw1, sw2, sw3, and ldo2 can regulate the feedback reference from

0.3625 V to 0.75 V in 12.5 mV steps. The output voltage thus ranges between

0.3625 * (1 + R1/R2) V and 0.75 * (1 + R1/R2) V. Regulators bb-out and ldo1

have a fixed 0.8 V reference and thus output 0.8 * (1 + R1/R2) V. The ldo3

regulator is fixed to 1.8 V on LTC3589 and to 2.8 V on LTC3589-1,2. The ldo4

regulator can output between 1.8 V and 3.3 V on LTC3589 and between 1.2 V

and 3.2 V on LTC3589-1,2 in four steps. The ldo1 standby regulator can not

be disabled and thus should have the regulator-always-on property set.
