The Western Digital MyBook Live has two memory-mapped GPIO controllers. Both GPIO controller only have a single 8-bit data register, where GPIO state can be read and/or written. Required properties: - compatible: should be "wd,mbl-gpio" - reg-names: must contain "dat" - data register - reg: address + size pairs describing the GPIO register sets; order must correspond with the order of entries in reg-names - #gpio-cells: must be set to 2. The first cell is the pin number and the second cell is used to specify the gpio polarity: 0 = active high 1 = active low - gpio-controller: Marks the device node as a gpio controller. Optional properties: - no-output: GPIOs are read-only. Examples: gpio0: gpio0@e0000000 { compatible = "wd,mbl-gpio"; reg-names = "dat"; reg = <0xe0000000 0x1>; #gpio-cells = <2>; gpio-controller; }; gpio1: gpio1@e0100000 { compatible = "wd,mbl-gpio"; reg-names = "dat"; reg = <0xe0100000 0x1>; #gpio-cells = <2>; gpio-controller; no-output; }; |
