* 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; |
|
}
