* ROHM BD71837 and BD71847 Power Management Integrated Circuit bindings
BD71837MWV and BD71847MWV are programmable Power Management ICs for powering
single-core, dual-core, and quad-core SoCs such as NXP-i.MX 8M. They are
optimized for low BOM cost and compact solution footprint. BD71837MWV
integrates 8 Buck regulators and 7 LDOs. BD71847MWV contains 6 Buck regulators
and 6 LDOs.
Datasheet for BD71837 is available at:
https://www.rohm.com/datasheet/BD71837MWV/bd71837mwv-e
Required properties:
- compatible : Should be "rohm,bd71837" for bd71837
"rohm,bd71847" for bd71847.
- 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>;
};
