Merge tag 'regulator-v4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "Another fairly quiet release, some new drivers with generic handling
  for minor features but nothing that makes a substantial difference
  outside of the subsystem or for most boards:

   - support for a bunch of new parameters which are present on enough
     regulators to be worth having generic handling for in the
     framework.

   - fixes for some issues with printing constraints during boot which
     should probably have gone in for v4.1 but didn't.

   - new drivers for Dialog DA9062, Maxim MAX77621 and Qualcomm SPMI
     regulators"

The regulator node houses sub-nodes for each regulator within the device. Each
sub-node is identified using the node's name, with valid values listed for each
of the PMICs below.

The content of each sub-node is defined by the standard binding for regulators -
see regulator.txt - with additional custom properties described below:
- regulator-initial-mode:
Usage: optional
Value type: <u32>
Descrption: 1 = Set initial mode to high power mode (HPM), also referred
to as NPM. HPM consumes more ground current than LPM, but
it can source significantly higher load current. HPM is not
available on boost type regulators. For voltage switch type
regulators, HPM implies that over current protection and
soft start are active all the time. 0 = Set initial mode to
low power mode (LPM).
