1APM X-Gene SoC GPIO controller bindings2 3This is a gpio controller that is part of the flash controller.4This gpio controller controls a total of 48 gpios.5 6Required properties:7- compatible: "apm,xgene-gpio" for X-Gene GPIO controller8- reg: Physical base address and size of the controller's registers9- #gpio-cells: Should be two.10 - first cell is the pin number11 - second cell is used to specify the gpio polarity:12 0 = active high13 1 = active low14- gpio-controller: Marks the device node as a GPIO controller.15 16Example:17 gpio0: gpio0@1701c000 {18 compatible = "apm,xgene-gpio";19 reg = <0x0 0x1701c000 0x0 0x40>;20 gpio-controller;21 #gpio-cells = <2>;22 };23
