* Generic Poweroff 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
|
||||
of.h .
|
||||
|
||||
Example:
|
||||
|
||||
act8846: act8846@5 {
|
||||
compatible = "active-semi,act8846";
|
||||
status = "okay";
|
||||
poweroff-source;
|
||||
}
