* ROHM BD70528 Power Management Integrated Circuit bindings BD70528MWV is an ultra-low quiescent current general purpose, single-chip, power management IC for battery-powered portable devices. The IC integrates 3 ultra-low current consumption buck converters, 3 LDOs and 2 LED Drivers. Also included are 4 GPIOs, a real-time clock (RTC), a 32kHz clock gate, high-accuracy VREF for use with an external ADC, flexible dual-input power path, 10 bit SAR ADC for battery temperature monitor and 1S battery charger with scalable charge currents. Required properties: - compatible : Should be "rohm,bd70528" - reg : I2C slave address. - interrupts : The interrupt line the device is connected to. - interrupt-controller : To indicate BD70528 acts as an interrupt controller. - #interrupt-cells : Should be 2. Usage is compliant to the 2 cells variant of ../interrupt-controller/interrupts.txt - gpio-controller : To indicate BD70528 acts as a GPIO controller. - #gpio-cells : Should be 2. The first cell is the pin number and the second cell is used to specify flags. See ../gpio/gpio.txt for more information. - #clock-cells : Should be 0. - regulators: : List of child nodes that specify the regulators. Please see ../regulator/rohm,bd70528-regulator.txt Optional properties: - clock-output-names : Should contain name for output clock. Example: /* External oscillator */ osc: oscillator { compatible = "fixed-clock"; #clock-cells = <1>; clock-frequency = <32768>; clock-output-names = "osc"; }; pmic: pmic@4b { compatible = "rohm,bd70528"; reg = <0x4b>; interrupt-parent = <&gpio1>; interrupts = <29 GPIO_ACTIVE_LOW>; clocks = <&osc 0>; #clock-cells = <0>; clock-output-names = "bd70528-32k-out"; #gpio-cells = <2>; gpio-controller; interrupt-controller; #interrupt-cells = <2>; regulators { buck1: BUCK1 { regulator-name = "buck1"; regulator-min-microvolt = <1200000>; regulator-max-microvolt = <3400000>; regulator-boot-on; regulator-ramp-delay = <125>; }; buck2: BUCK2 { regulator-name = "buck2"; regulator-min-microvolt = <1200000>; regulator-max-microvolt = <3300000>; regulator-boot-on; regulator-ramp-delay = <125>; }; buck3: BUCK3 { regulator-name = "buck3"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <1800000>; regulator-boot-on; regulator-ramp-delay = <250>; }; ldo1: LDO1 { regulator-name = "ldo1"; regulator-min-microvolt = <1650000>; regulator-max-microvolt = <3300000>; regulator-boot-on; }; ldo2: LDO2 { regulator-name = "ldo2"; regulator-min-microvolt = <1650000>; regulator-max-microvolt = <3300000>; regulator-boot-on; }; ldo3: LDO3 { regulator-name = "ldo3"; regulator-min-microvolt = <1650000>; regulator-max-microvolt = <3300000>; }; led_ldo1: LED_LDO1 { regulator-name = "led_ldo1"; regulator-min-microvolt = <200000>; regulator-max-microvolt = <300000>; }; led_ldo2: LED_LDO2 { regulator-name = "led_ldo2"; regulator-min-microvolt = <200000>; regulator-max-microvolt = <300000>; }; }; }; |
