Merge tag 'regulator-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator 

Pull regulator updates from Mark Brown:
 "This is a very quiet release, there was no work on the core and a good
  chunk of the updates were the result of conversions to use newer GPIO
  APIs.

  We did gain support for Analog ADP5055 and TI TPS65214 devices, and
  there's a new restart handler for the PCA9450 which allows devices
  using it to be properly power cycled on reboot, but otherwise it's
  minor fixes and API updates"

title: Analog Devices ADP5055 Triple Buck Regulator



maintainers:

  - Alexis Czezar Torreno <alexisczezar.torreno@analog.com>



description: |

  The ADP5055 combines three high performance buck regulator. The device enables

  direct connection to high input voltages up to 18 V with no preregulators.

          GPIO specifier to enable the GPIO control for each regulator. The

          driver supports two modes of enable, hardware only (GPIOs) or software

          only (Registers). Pure hardware enabling requires each regulator to

          contain this property. If at least one regulator does not have this,

          the driver automatically switches to software only mode.
