Documentation: devicetree: standardize/consolidate on "wakeup-source" property Currently different drivers use multiple forms of annotating devices that should be set up as wakeup sources for the system. This patch adds a separate binding document inorder to standardize and consolidate to use "wakeup-source" boolean property to mark the devices as wakeup capable.

Specifying wakeup capability for devices
============================================
Any device nodes
----------------
Nodes that describe devices which has wakeup capability must contain an
"wakeup-source" boolean property.
Also, if device is marked as a wakeup source, then all the primary
interrupt(s) can be used as wakeup interrupt(s).
However if the devices have dedicated interrupt as the wakeup source
then they need to specify/identify the same using device specific
interrupt name. In such cases only that interrupt can be used as wakeup
interrupt.

Examples
--------
1. With "wakeup" interrupt name
device@10000 {
compatible = "vendor,device-id";
reg = <0x10000 0x1000>;
interrupts = <0 19 4>, <0 21 4>, <0 22 4>;
interrupt-names = "ack", "err", "wakeup";
wakeup-source;
};
2. Without "wakeup" interrupt name
embedded-controller {
compatible = "google,cros-ec-i2c";
reg = <0x1e>;
interrupts = <6 0>;
interrupt-parent = <&gpx1>;
pinctrl-names = "default";
pinctrl-0 = <&ec_irq>;
wakeup-source;
};
3. Without interrupts
gpio_keys {
compatible = "gpio-keys";
#address-cells = <1>;
#size-cells = <0>;
