This series adds support for max77650 ultra low-power PMIC. It provides
the core mfd driver and a set of five sub-drivers for the regulator,
power supply, gpio, leds and input subsystems.

Patches 1-6 add the DT binding documents. Patches 7-12 add all drivers.
Last patch adds a MAINTAINERS entry for this device.

Note that patch 8/13 depends on commit 03c87b95ac04 ("regulator: provide
rdev_get_regmap()") which was picked up by Mark Brown for v5.1.

v1 -> v2:

General:
- use C++ style comments for the SPDX license identifier and the
  copyright header
- s/MODULE_LICENSE("GPL")/MODULE_LICENSE("GPL v2")/
- lookup the virtual interrupt numbers in the MFD driver, setup
  resources for child devices and use platform_get_irq_byname()
  in sub-drivers
- picked up review tags
- use devm_request_any_context_irq() for interrupt requests

LEDs:
- changed the max77650_leds_ prefix to max77650_led_
- drop the max77650_leds structure as the only field it held was the
  regmap pointer, move said pointer to struct max77650_led
- change the driver name to "max77650-led"
- drop the last return value check and return the result of
  regmap_write() directly
- change the labeling scheme to one consistent with other LED drivers

ONKEY:
- drop the key reporting helper and call the input functions directly
  from interrupt handlers
- rename the rv local variable to error
- drop parent device asignment

Regulator:
- drop the unnecessary init_data lookup from the driver code
- drop unnecessary include

Charger:
- disable the charger on driver remove
- change the power supply type to POWER_SUPPLY_TYPE_USB

GPIO:
- drop interrupt support until we have correct implementation of hierarchical
  irqs in gpiolib

v2 -> v3:

General:
- dropped regulator patches as they're already in Mark Brown's branch

LED:
- fix the compatible string in the DT binding example
- use the max_brightness property
- use a common prefix ("MAX77650_LED") for all defines in the driver

MFD:
- add the MODULE_DEVICE_TABLE()
- add a sentinel to the of_device_id array
- constify the pointers to irq names
- use an enum instead of defines for interrupt indexes
