1* ROHM BD71837 Power Management Integrated Circuit bindings 2 3BD71837MWV is a programmable Power Management IC for powering single-core, 4dual-core, and quad-core SoCs such as NXP-i.MX 8M. It is optimized for 5low BOM cost and compact solution footprint. It integrates 8 Buck 6egulators and 7 LDOs to provide all the power rails required by the SoC and 7the commonly used peripherals. 8 9Datasheet for PMIC is available at: 10https://www.rohm.com/datasheet/BD71837MWV/bd71837mwv-e 11 12Required properties: 13 - compatible : Should be "rohm,bd71837". 14 - reg : I2C slave address. 15 - interrupt-parent : Phandle to the parent interrupt controller. 16 - interrupts : The interrupt line the device is connected to. 17 - clocks : The parent clock connected to PMIC. If this is missing 18 32768 KHz clock is assumed. 19 - #clock-cells : Should be 0. 20 - regulators: : List of child nodes that specify the regulators. 21 Please see ../regulator/rohm,bd71837-regulator.txt 22 23Optional properties: 24- clock-output-names : Should contain name for output clock. 25 26Example: 27 28 /* external oscillator node */ 29 osc: oscillator { 30 compatible = "fixed-clock"; 31 #clock-cells = <1>; 32 clock-frequency = <32768>; 33 clock-output-names = "osc"; 34 }; 35 36 pmic: pmic@4b { 37 compatible = "rohm,bd71837"; 38 reg = <0x4b>; 39 interrupt-parent = <&gpio1>; 40 interrupts = <29 GPIO_ACTIVE_LOW>; 41 interrupt-names = "irq"; 42 #clock-cells = <0>; 43 clocks = <&osc 0>; 44 clock-output-names = "bd71837-32k-out"; 45 46 regulators { 47 buck1: BUCK1 { 48 regulator-name = "buck1"; 49 regulator-min-microvolt = <700000>; 50 regulator-max-microvolt = <1300000>; 51 regulator-boot-on; 52 regulator-ramp-delay = <1250>; 53 }; 54 }; 55 }; 56 57 /* Clock consumer node */ 58 rtc@0 { 59 compatible = "company,my-rtc"; 60 clock-names = "my-clock"; 61 clocks = <&pmic>; 62 }; 63
