* 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;
|
|
}
