+* ROHM BD71837 Power Management Integrated Circuit bindings
+
+BD71837MWV is a programmable Power Management IC for powering single-core,
+dual-core, and quad-core SoCs such as NXP-i.MX 8M. It is optimized for
+low BOM cost and compact solution footprint. It integrates 8 Buck
+egulators and 7 LDOs to provide all the power rails required by the SoC and
+the commonly used peripherals.
+
+Datasheet for PMIC is available at:
+https://www.rohm.com/datasheet/BD71837MWV/bd71837mwv-e
+
+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.
+ - clocks : The parent clock connected to PMIC. If this is missing
+ 32768 KHz clock is assumed.
+ - #clock-cells : Should be 0.
+ - regulators: : List of child nodes that specify the regulators.
+ Please see ../regulator/rohm,bd71837-regulator.txt
+
+Optional properties:
+- clock-output-names : Should contain name for output clock.
+
+Example:
+
+ /* external oscillator node */
+ osc: oscillator {
+ compatible = "fixed-clock";
+ #clock-cells = <1>;
+ clock-frequency = <32768>;
+ clock-output-names = "osc";
+ };
+
+ pmic: pmic@4b {
+ compatible = "rohm,bd71837";
+ reg = <0x4b>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <29 GPIO_ACTIVE_LOW>;
+ interrupt-names = "irq";
+ #clock-cells = <0>;
+ clocks = <&osc 0>;
+ clock-output-names = "bd71837-32k-out";
+
+ regulators {
+ buck1: BUCK1 {
+ regulator-name = "buck1";
+ regulator-min-microvolt = <700000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-boot-on;
+ regulator-ramp-delay = <1250>;
+ };
+ };
+ };
+
+ /* Clock consumer node */
+ rtc@0 {
+ compatible = "company,my-rtc";
+ clock-names = "my-clock";
+ clocks = <&pmic>;
+ };
