      1Specifying wakeup capability for devices
      2============================================
      3
      4Any device nodes
      5----------------
      6Nodes that describe devices which has wakeup capability must contain an
      7"wakeup-source" boolean property.
      8
      9Also, if device is marked as a wakeup source, then all the primary
     10interrupt(s) can be used as wakeup interrupt(s).
     11
     12However if the devices have dedicated interrupt as the wakeup source
     13then they need to specify/identify the same using device specific
     14interrupt name. In such cases only that interrupt can be used as wakeup
     15interrupt.

     30Examples
     31--------
     32
     331. With "wakeup" interrupt name
     34
     35	device@10000 {
     36		compatible	= "vendor,device-id";
     37		reg		= <0x10000 0x1000>;
     38		interrupts	= <0 19 4>, <0 21 4>, <0 22 4>;
     39		interrupt-names	= "ack", "err", "wakeup";
     40		wakeup-source;
     41	};
     42
     432. Without "wakeup" interrupt name
     44
     45	embedded-controller {
     46		compatible = "google,cros-ec-i2c";
     47		reg = <0x1e>;
     48		interrupts = <6 0>;
     49		interrupt-parent = <&gpx1>;
     50		pinctrl-names = "default";
     51		pinctrl-0 = <&ec_irq>;
     52		wakeup-source;
     53	};
     54
     553. Without interrupts
     56
     57	gpio_keys {
     58		compatible = "gpio-keys";
     59		#address-cells = <1>;
     60		#size-cells = <0>;
     61
     62		button@1 {
     63			debounce-interval = <50>;
     64			wakeup-source;
     65			linux,code = <116>;
     66			label = "POWER";
     67			gpios = <&iofpga_gpio0 0 0x4>;
     68		};
     69		[....]
     70	};
