The Maxim MAX77686 is a Power Management IC which includes voltage and current regulators, RTC and clock outputs. The MAX77686 provides three 32.768khz clock outputs that can be controlled (gated/ungated) over I2C. The clock IDs are defined as preprocessor macros in dt-bindings/clock/maxim,max77686.h. properties: compatible: const: maxim,max77686 '#clock-cells': const: 1 interrupts: maxItems: 1 reg: maxItems: 1 voltage-regulators: $ref: ../regulator/maxim,max77686.yaml description: List of child nodes that specify the regulators. wakeup-source: true required: - compatible - '#clock-cells' - reg additionalProperties: false examples: - | #include #include i2c { #address-cells = <1>; #size-cells = <0>; max77686: pmic@9 { compatible = "maxim,max77686"; reg = <0x09>; interrupt-parent = <&gpx0>; interrupts = <7 IRQ_TYPE_LEVEL_LOW>; pinctrl-0 = <&max77686_irq>; pinctrl-names = "default"; wakeup-source; #clock-cells = <1>; voltage-regulators { LDO1 { regulator-name = "VALIVE_1.0V_AP"; regulator-min-microvolt = <1000000>; regulator-max-microvolt = <1000000>; regulator-always-on; }; LDO2 { regulator-name = "VM1M2_1.2V_AP"; regulator-min-microvolt = <1200000>; regulator-max-microvolt = <1200000>; regulator-always-on; regulator-state-mem { regulator-on-in-suspend; }; }; // ...
