Maxim MAX8952 voltage regulator Required properties: - compatible: must be equal to "maxim,max8952" - reg: I2C slave address, usually 0x60 - max8952,dvs-mode-microvolt: array of 4 integer values defining DVS voltages in microvolts. All values must be from range <770000, 1400000> - any required generic properties defined in regulator.txt Optional properties: - max8952,vid-gpios: array of two GPIO pins used for DVS voltage selection - max8952,en-gpio: GPIO used to control enable status of regulator - max8952,default-mode: index of default DVS voltage, from <0, 3> range - max8952,sync-freq: sync frequency, must be one of following values: - 0: 26 MHz - 1: 13 MHz - 2: 19.2 MHz Defaults to 26 MHz if not specified. - max8952,ramp-speed: voltage ramp speed, must be one of following values: - 0: 32mV/us - 1: 16mV/us - 2: 8mV/us - 3: 4mV/us - 4: 2mV/us - 5: 1mV/us - 6: 0.5mV/us - 7: 0.25mV/us Defaults to 32mV/us if not specified. - any available generic properties defined in regulator.txt Example: vdd_arm_reg: pmic@60 { compatible = "maxim,max8952"; reg = <0x60>; /* max8952-specific properties */ max8952,vid-gpios = <&gpx0 3 0>, <&gpx0 4 0>; max8952,en-gpio = <&gpx0 1 0>; max8952,default-mode = <0>; max8952,dvs-mode-microvolt = <1250000>, <1200000>, <1050000>, <950000>; max8952,sync-freq = <0>; max8952,ramp-speed = <0>; /* generic regulator properties */ regulator-name = "vdd_arm"; regulator-min-microvolt = <770000>; regulator-max-microvolt = <1400000>; regulator-always-on; regulator-boot-on; }; |
