1AXP209 GPIO controller 2 3This driver follows the usual GPIO bindings found in 4Documentation/devicetree/bindings/gpio/gpio.txt 5 6Required properties: 7- compatible: Should be "x-powers,axp209-gpio" 8- #gpio-cells: Should be two. The first cell is the pin number and the 9 second is the GPIO flags. 10- gpio-controller: Marks the device node as a GPIO controller. 11 12This node must be a subnode of the axp20x PMIC, documented in 13Documentation/devicetree/bindings/mfd/axp20x.txt 14 15Example: 16 17axp209: pmic@34 { 18 compatible = "x-powers,axp209"; 19 reg = <0x34>; 20 interrupt-parent = <&nmi_intc>; 21 interrupts = <0 IRQ_TYPE_LEVEL_LOW>; 22 interrupt-controller; 23 #interrupt-cells = <1>; 24 25 axp_gpio: gpio { 26 compatible = "x-powers,axp209-gpio"; 27 gpio-controller; 28 #gpio-cells = <2>; 29 }; 30}; 31
