1* Generic system power control capability
2
3Power-management integrated circuits or miscellaneous hardware components are
4sometimes able to control the system power. The device driver associated with these
5components might need to define this capability, which tells the kernel that
6it can be used to switch off the system. The corresponding device must have the
7standard property "system-power-controller" in its device node. This property
8marks the device as able to control the system power. In order to test if this
9property is found programmatically, use the helper function
10"of_device_is_system_power_controller" from of.h .
