* include/linux/platform.h - platform driver definitions
|
|
*
|
|
* Because of the prolific consumerism of the average American,
|
|
* and the dominant marketing budgets of PC OEMs, we have been
|
|
* blessed with frequent updates of the PC architecture.
|
|
*
|
|
* While most of these calls are singular per architecture, they
|
|
* require an extra layer of abstraction on the x86 so the right
|
|
* subsystem gets the right call.
|
|
*
|
|
* Basically, this consolidates the power off and reboot callbacks
|
|
* into one structure, as well as adding power management hooks.
|
|
*
|
|
* When adding a platform driver, please make sure all callbacks are
|
|
* filled. There are defaults defined below that do nothing; use those
|
|
* if you do not support that callback.
