+* Generic system power control capability
+
+Power-management integrated circuits or miscellaneous hardware components are
+sometimes able to control the system power. The device driver associated with these
+components might need to define this capability, which tells the kernel that
+it can be used to switch off the system. The corresponding device must have the
+standard property "system-power-controller" in its device node. This property
+marks the device as able to control the system power. In order to test if this
+property is found programmatically, use the helper function
+"of_device_is_system_power_controller" from of.h .
+
+Example:
+
+act8846: act8846@5 {
+	 compatible = "active-semi,act8846";
+	 system-power-controller;
+}
