[PATCH v2 0/4] Add support for Ricoh RN5T618 PMIC

[Beniamino Galvani]

Ricoh RN5T618 is a power management IC which includes 3 step-down DCDC
converters, 7 low-dropout regulators, a Li-ion battery charger, fuel
gauge, ADC, GPIOs and a watchdog timer.

This series adds a MFD core driver and separate drivers to support the
regulator and watchdog functionalities.

The patchset has been tested on a Tronsmart Vega S89 Elite TV box on
top of other patches needed to support the Amlogic Meson SoC. The tree
with all the changes is available at:

  https://github.com/bengal/linux/tree/rn5t618-v2

Changes since v1:
  - moved all header file changes to the first patch
  - mfd: allow modular build
  - mfd: removed printk after mfd registration
  - regulator: rebased on regulator/for-next
  - wdt: initialized heartbeat parameter to 0 instead of -1
  - wdt: simplified code path in set_timeout function
  - wdt: fixed module unloading
  - wdt: made 'time' unsigned in struct rn5t618_wdt_map

  mfd: Add Ricoh RN5T618 PMIC core driver
  regulator: add driver for Ricoh RN5T618 regulators
  watchdog: add driver for Ricoh RN5T618 watchdog
  mfd: rn5t618: document device tree bindings
