Changes in v12:
- move fuelgauge bindings to separate patch because separate device
- move charger bindings to separate patch because separate device
- description: mention this is a part

Changes in v11:
- remove reviewed tags because of major changes
- none of children are supposed to have addresses, all nodes are
unit-less

Changes in v10:
- leds: replace label with color and function properties
- leds: add support for leds-class-multicolor
- move fuelgauge node to patternProperties "^fuel-gauge@[0-9a-f]+$"
  to comply with max17042 binding

Changes in v9:
- replace max77705 fuel gauge with max17042
- remove monitored battery because not supported by max17042

Changes in v8:
- fix leds compatible

Changes in v6:
- unevaluatedProperties must be false
- drop excessive sentence from description,
  just describe the device
- change leds compatible to maxim,max77705-rgb

Changes in v5:
- formatting changes
- add unevaluatedProperties: false for nodes referencing
  common schemas
- remove additionalProperties on nodes with
  unevaluatedProperties: false
- add min and max to led index
Changes in v4:
- change dts example intendation from tabs
 to spaces
- remove interrupt-names property
- remove obvious reg description
- split long(>80) lines
