		This module is part of the ROHM BD71828 MFD device. For more details
		see Documentation/devicetree/bindings/mfd/rohm,bd71828-pmic.yaml.

		The LED controller is represented as a sub-node of the PMIC node on the device
		tree.

		The device has two LED outputs referred as GRNLED and AMBLED in data-sheet.

		description: \|
		BD71828GW is a single-chip power management IC for battery-powered portable
		devices. The IC integrates 7 buck converters, 7 LDOs, and a 1500 mA
		single-cell linear charger. Also included is a Coulomb counter, a real-time
		clock (RTC), and a 32.768 kHz clock gate.
