+-------------------------------
+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 properties:
+- regulators: This is the list of child nodes that specify the regulator
+ initialization data for defined regulators. Generic regulator bindings
+ are described in regulator/regulator.txt.
+
+ The valid regulator nodes for BCM59056 are:
+ rfldo, camldo1, camldo2, simldo1, simldo2, sdldo, sdxldo,
+ mmcldo1, mmcldo2, audldo, micldo, usbldo, vibldo,
+ csr, iosr1, iosr2, msr, sdsr1, sdsr2, vsr
+
+Example:
+ pmu: bcm59056@8 {
+ compatible = "brcm,bcm59056";
+ reg = <0x08>;
+ interrupts = <GIC_SPI 215 IRQ_TYPE_LEVEL_HIGH>;
+ regulators {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ rfldo_reg: rfldo {
+ regulator-min-microvolt = <1200000>;
+ regulator-max-microvolt = <3300000>;
+ };
+
+ ...
+ };
+ };
