From: Bartosz Golaszewski <[e-mail]>

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 1-4 add the DT binding documents. Patches 5-9 add all drivers.
Last patch adds a MAINTAINERS entry for this device.

The regulator part has already been picked up into the regulator tree.

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

v3 -> v4:

GPIO:
- as discussed with Linus Walleij: the gpio-controller is now part of
  the core mfd module (we don't spawn a sub-node anymore), the binding
  document for GPIO has been dropped, the GPIO properties have been
  defined in the binding document for the mfd core, the interrupt
  functionality has been reintroduced with the irq directly passed from
  the mfd part
- due to the above changes the Reviewed-by tag from Linus was dropped
