-* Generic Poweroff capability
+* Generic system power control capability
 
-Power-management integrated circuits or miscellaneous harware components are
-sometimes able to control the system power. The device driver associated to these
-components might needs to define poweroff capability, which tells to the kernel
-how to switch off the system. The corresponding driver must have the standard
-property "poweroff-source" in its device node. This property marks the device as
-able to shutdown the system. In order to test if this property is found
-programmatically, use the helper function "of_system_has_poweroff_source" from

 Example:
 
 act8846: act8846@5 {
         compatible = "active-semi,act8846";
         status = "okay";
-        poweroff-source;
+        system-power-controller;
