It integrates 5 buck converters, 8 LDOs, a boost driver for LED and a 500 mA single-cell linear charger. Also included is a Coulomb counter, a real-time clock (RTC), and a 32.768 kHz clock gate and two GPOs. properties: compatible: const: rohm,bd71815 reg: description: I2C slave address. maxItems: 1 interrupts: maxItems: 1 gpio-controller: true "#gpio-cells": const: 2 description: | The first cell is the pin number and the second cell is used to specify flags.

This property can be used to mark the pins which should not be configured for GPIO. Please see the ../gpio/gpio.txt for more information. rohm,enable-hidden-gpo: description: | The BD71815 has undocumented GPO at pin E5. Pin is marked as GND at the data-sheet as it's location in the middle of GND pins makes it hard to use on PCB. If your board has managed to use this pin you can enable the second GPO by defining this property. Dont enable this if you are unsure about how the E5 pin is connected on your board. type: boolean required: - compatible - reg - interrupts - clocks - "#clock-cells" - regulators - gpio-controller - "#gpio-cells" additionalProperties: false examples: - | #include #include i2c { #address-cells = <1>; #size-cells = <0>; pmic: pmic@4b { compatible = "rohm,bd71815"; reg = <0x4b>; interrupt-parent = <&gpio1>; interrupts = <29 IRQ_TYPE_LEVEL_LOW>; clocks = <&osc 0>; #clock-cells = <0>; clock-output-names = "bd71815-32k-out"; gpio-controller; #gpio-cells = <2>; rohm,charger-sense-resistor-ohms = <10000000>; regulators { buck1: buck1 { regulator-name = "buck1"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <2000000>; regulator-always-on; regulator-ramp-delay = <1250>; rohm,dvs-run-voltage = <1150000>; rohm,dvs-suspend-voltage = <950000>; }; buck2: buck2 { regulator-name = "buck2"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <2000000>; regulator-always-on; regulator-ramp-delay = <1250>; rohm,dvs-run-voltage = <1150000>; rohm,dvs-suspend-voltage = <950000>; }; buck3: buck3 { regulator-name = "buck3"; regulator-min-microvolt = <1200000>; regulator-max-microvolt = <2700000>; regulator-always-on; }; buck4: buck4 { regulator-name = "buck4"; regulator-min-microvolt = <1100000>; regulator-max-microvolt = <1850000>; regulator-always-on; }; buck5: buck5 { regulator-name = "buck5"; regulator-min-microvolt = <1800000>; regulator-max-microvolt = <3300000>; regulator-always-on; }; ldo1: ldo1 { regulator-name = "ldo1"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <3300000>; regulator-always-on; }; ldo2: ldo2 { regulator-name = "ldo2"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <3300000>; regulator-always-on; }; ldo3: ldo3 { regulator-name = "ldo3"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <3300000>; regulator-always-on; }; ldo4: ldo4 { regulator-name = "ldo4"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <3300000>; regulator-always-on; }; ldo5: ldo5 { regulator-name = "ldo5"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <3300000>; regulator-always-on; }; ldo6: ldodvref { regulator-name = "ldodvref"; regulator-always-on; }; ldo7: ldolpsr { regulator-name = "ldolpsr"; regulator-always-on; }; boost: wled { regulator-name = "wled"; regulator-min-microamp = <10>; regulator-max-microamp = <25000>; }; }; }; };
