Setup 1 for PWM mode, 0 for AUTO (PWM/PFM) mode. The DCDC regulators work in a mixed PWM/PFM mode, using PFM under light loads and switching to PWM for heavier loads. Forcing PWM mode trades efficiency under light loads for lower output noise. This probably makes sense for HiFi audio related applications that aren't battery constrained. additionalProperties: false required: - compatible - reg - "#interrupt-cells" - interrupt-controller additionalProperties: false examples: - | i2c { #address-cells = <1>; #size-cells = <0>; pmic@30 { compatible = "x-powers,axp152"; reg = <0x30>; interrupts = <0>; interrupt-controller; #interrupt-cells = <1>; }; }; - | #include i2c { #address-cells = <1>; #size-cells = <0>; pmic@34 { compatible = "x-powers,axp209"; reg = <0x34>; interrupt-parent = <&nmi_intc>; interrupts = <0 IRQ_TYPE_LEVEL_LOW>; interrupt-controller; #interrupt-cells = <1>; ac_power_supply: ac-power { compatible = "x-powers,axp202-ac-power-supply"; }; axp_adc: adc { compatible = "x-powers,axp209-adc"; #io-channel-cells = <1>; }; axp_gpio: gpio { compatible = "x-powers,axp209-gpio"; gpio-controller; #gpio-cells = <2>; gpio0-adc-pin { pins = "GPIO0"; function = "adc"; }; }; battery_power_supply: battery-power { compatible = "x-powers,axp209-battery-power-supply"; }; regulators { /* Default work frequency for buck regulators */ x-powers,dcdc-freq = <1500>; reg_dcdc2: dcdc2 { regulator-always-on; regulator-min-microvolt = <1000000>; regulator-max-microvolt = <1450000>; regulator-name = "vdd-cpu"; }; reg_dcdc3: dcdc3 { regulator-always-on; regulator-min-microvolt = <1000000>; regulator-max-microvolt = <1400000>; regulator-name = "vdd-int-dll"; }; reg_ldo1: ldo1 { /* LDO1 is a fixed output regulator */ regulator-always-on; regulator-min-microvolt = <1300000>; regulator-max-microvolt = <1300000>; regulator-name = "vdd-rtc"; }; reg_ldo2: ldo2 { regulator-always-on; regulator-min-microvolt = <3000000>; regulator-max-microvolt = <3000000>; regulator-name = "avcc"; }; reg_ldo3: ldo3 { regulator-name = "ldo3"; }; reg_ldo4: ldo4 { regulator-name = "ldo4"; }; reg_ldo5: ldo5 { regulator-name = "ldo5"; }; }; usb_power_supply: usb-power { compatible = "x-powers,axp202-usb-power-supply"; }; }; };
