Pull regulator updates from Mark Brown:
 "The diffstat and changelog here is dominated by Lee Jones' heroic
  efforts to sync the ab8500 driver that's been maintained out of tree
  with mainline (plus Axel's cleanup work on the results) but there's a
  few other things here:

   - Axel Lin added regulator_map_voltage_ascend() optimising a common
     pattern for drivers using the core code.
   - Milo Kim tought the regulator core to handle regulators sharing an
     enable GPIO, avoiding the need to do hacks to support such systems.
   - Andrew Bresticker added code to handle missing supplies for
     regulators more sensibly for device tree systems, reducing the need
     for stubbing there.

  plus the usual batch of driver specific updates and fixes"

Maxim MAX8952 voltage regulator

Required properties:
- compatible: must be equal to "maxim,max8952"
- reg: I2C slave address, usually 0x60
- max8952,dvs-mode-microvolt: array of 4 integer values defining DVS voltages
in microvolts. All values must be from range <770000, 1400000>
- any required generic properties defined in regulator.txt

Optional properties:
- max8952,vid-gpios: array of two GPIO pins used for DVS voltage selection
- max8952,en-gpio: GPIO used to control enable status of regulator
- max8952,default-mode: index of default DVS voltage, from <0, 3> range
- max8952,sync-freq: sync frequency, must be one of following values:
- 0: 26 MHz
- 1: 13 MHz
- 2: 19.2 MHz
Defaults to 26 MHz if not specified.
- max8952,ramp-speed: voltage ramp speed, must be one of following values:
- 0: 32mV/us
- 1: 16mV/us
- 2: 8mV/us
- 3: 4mV/us
- 4: 2mV/us
- 5: 1mV/us
- 6: 0.5mV/us
- 7: 0.25mV/us
Defaults to 32mV/us if not specified.
- any available generic properties defined in regulator.txt

vdd_arm_reg: pmic@60 {
compatible = "maxim,max8952";
reg = <0x60>;

/* max8952-specific properties */
