The GPIO-controller module is represented as part of the top-level PMIC node. The device exposes a single GPIO line. For device-tree bindings of other sub-modules (regulator, power supply, LEDs and onkey) refer to the binding documents under the respective sub-system directories. properties: compatible: const: maxim,max77650 reg: description: I2C device address. maxItems: 1 interrupts: maxItems: 1 interrupt-controller: true "#interrupt-cells": const: 2 description: The first cell is the IRQ number, the second cell is the trigger type. gpio-controller: true "#gpio-cells": const: 2 description: The first cell is the pin number and the second cell is used to specify the gpio active state. gpio-line-names: maxItems: 1 description: Single string containing the name of the GPIO line. regulators: $ref: /schemas/regulator/max77650-regulator.yaml charger: $ref: /schemas/power/supply/max77650-charger.yaml leds: $ref: /schemas/leds/leds-max77650.yaml onkey: $ref: /schemas/input/max77650-onkey.yaml required: - compatible - reg - interrupts - interrupt-controller - "#interrupt-cells" - gpio-controller - "#gpio-cells" additionalProperties: false examples: - | #include <dt-bindings/interrupt-controller/irq.h> #include <dt-bindings/input/linux-event-codes.h> i2c { #address-cells = <1>; #size-cells = <0>; pmic@48 { compatible = "maxim,max77650"; reg = <0x48>; interrupt-controller; interrupt-parent = <&gpio2>; #interrupt-cells = <2>; interrupts = <3 IRQ_TYPE_LEVEL_LOW>; gpio-controller; #gpio-cells = <2>; gpio-line-names = "max77650-charger"; regulators { compatible = "maxim,max77650-regulator"; max77650_ldo: regulator-ldo { regulator-name = "max77650-ldo"; regulator-min-microvolt = <1350000>; regulator-max-microvolt = <2937500>; }; max77650_sbb0: regulator-sbb0 { regulator-name = "max77650-sbb0"; regulator-min-microvolt = <800000>; regulator-max-microvolt = <1587500>; }; }; charger { compatible = "maxim,max77650-charger"; input-voltage-min-microvolt = <4200000>; input-current-limit-microamp = <285000>; }; leds { compatible = "maxim,max77650-led"; #address-cells = <1>; #size-cells = <0>; led@0 { reg = <0>; label = "blue:usr0"; }; led@1 { reg = <1>; label = "red:usr1"; linux,default-trigger = "heartbeat"; }; led@2 { reg = <2>; label = "green:usr2"; }; }; onkey { compatible = "maxim,max77650-onkey"; linux,code = <KEY_END>; maxim,onkey-slide; }; }; }; |
