-------------------------------
BCM590xx Power Management Units
-------------------------------

Required properties:
- compatible: "brcm,bcm59056"
- reg: I2C slave address
- interrupts: interrupt for the PMU. Generic interrupt client node bindings
  are described in interrupt-controller/interrupts.txt

------------------
Voltage Regulators
------------------

Optional child nodes:
- regulators: container node for regulators following the generic
  regulator binding in regulator/regulator.txt

  The valid regulator node names for BCM59056 are:
  	rfldo, camldo1, camldo2, simldo1, simldo2, sdldo, sdxldo,
	mmcldo1, mmcldo2, audldo, micldo, usbldo, vibldo,
	csr, iosr1, iosr2, msr, sdsr1, sdsr2, vsr,
	gpldo1, gpldo2, gpldo3, gpldo4, gpldo5, gpldo6,
	vbus

Example:
	pmu: bcm59056@8 {
		compatible = "brcm,bcm59056";
		reg = <0x08>;
		interrupts = <GIC_SPI 215 IRQ_TYPE_LEVEL_HIGH>;
		regulators {
			rfldo_reg: rfldo {
				regulator-min-microvolt = <1200000>;
				regulator-max-microvolt = <3300000>;
			};

			...
		};
	};
