Pull regulator updates from Mark Brown:
 "The biggest chunk of the regulator changes for this release outside of
  the new drivers is the conversion of the fixed regulator to use the
  GPIO descriptor API, there's a small addition to the GPIO API plus a
  bunch of updates to board files to implement it. This is some really
  welcome work from Linus Walleij that's had a bunch of review and has
  been sitting in -next for a while so I'm fairly happy there's no major
  issues.

   - Helpers for overlapping linear ranges.

   - Display opmode and consumer requested load in the regualtor_summary
     file in debugfs, plus a fix there.

   - Support for the fun and entertaining power off mechanism that the
     pfuze100 hardware implements.

   - Conversion of the fixed regulator API to use GPIO descriptors,
     including pulling in a bunch of patches to a bunch of board files.

   - New drivers for Cirrus Logic Lochnagar, Qualcomm PMS405, Rohm
     BD71847, ST PMIC1, and TI LM363x devices"

BD71837MWV is a programmable Power Management IC for powering single-core,
dual-core, and quad-core SoCs such as NXP-i.MX 8M. It is optimized for
low BOM cost and compact solution footprint. It integrates 8 Buck
egulators and 7 LDOs to provide all the power rails required by the SoC and
the commonly used peripherals.

Use this option if the SoC should be powered off by external power

As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.

- buck4 for Buck BUCK4
- ldo1 for LDO LDO1
- ldo2 for LDO LDO2

- pwr_sw2 for SW_OUT switch
Switches are fixed voltage regulators with only enable/disable capability.
Optional properties:
- st,mask-reset: mask reset for this regulator: the regulator configuration
is maintained during pmic reset.
- regulator-pull-down: enable high pull down
if not specified light pull down is used
- regulator-over-current-protection:
if set, all regulators are switched off in case of over-current detection
on this regulator,
if not set, the driver only sends an over-current event.
- interrupt-parent: phandle to the parent interrupt controller
- interrupts: index of current limit detection interrupt
- <regulator>-supply: phandle to the parent supply/regulator node
each regulator supply can be described except vref_ddr.
