+* ROHM BD71837 Power Management Integrated Circuit bindings
+
+BD71837MWV is a programmable Power Management IC for powering single-core,
+dual-core, and quad-core SoC’s such as NXP-i.MX 8M. It is optimized for
+low BOM cost and compact solution footprint. It integrates 8 Buck
+egulators and 7 LDO’s to provide all the power rails required by the SoC and
+the commonly used peripherals.
+
+Required properties:
+ - compatible : Should be "rohm,bd71837".
+ - reg : I2C slave address.
+ - interrupt-parent : Phandle to the parent interrupt controller.
+ - interrupts : The interrupt line the device is connected to.
+ - interrupt-controller : Marks the device node as an interrupt controller.
+ - #interrupt-cells : The number of cells to describe an IRQ, should be 1 or 2.
+ The first cell is the IRQ number.
+ The second cell if present is the flags, encoded as trigger
+ masks from ../interrupt-controller/interrupts.txt.
+ - regulators: : List of child nodes that specify the regulators
+ Please see ../regulator/rohm,bd71837-regulator.txt
+ - clock: : Please see ../clock/rohm,bd71837-clock.txt
+
+Example:
+
+ pmic: bd71837@4b {
+ compatible = "rohm,bd71837";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x4b>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <29 GPIO_ACTIVE_LOW>;
+ interrupt-names = "irq";
+ #interrupt-cells = <1>;
+ interrupt-controller;
+
+ regulators {
+ buck1: BUCK1 {
+ regulator-name = "buck1";
+ regulator-min-microvolt = <700000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-boot-on;
+ regulator-ramp-delay = <1250>;
+ };
+ ...
+ };
+ clk: bd71837-32k-out {
+ compatible = "rohm,bd71837-clk";
+ #clock-cells = <0>;
+ clock-frequency = <32768>;
+ clock-output-names = "bd71837-32k-out";
+ };
+ };
