| 2 | * include/linux/platform.h - platform driver definitions |
||
| 3 | * |
||
| 4 | * Because of the prolific consumerism of the average American, |
||
| 5 | * and the dominant marketing budgets of PC OEMs, we have been |
||
| 6 | * blessed with frequent updates of the PC architecture. |
||
| 7 | * |
||
| 8 | * While most of these calls are singular per architecture, they |
||
| 9 | * require an extra layer of abstraction on the x86 so the right |
||
| 10 | * subsystem gets the right call. |
||
| 11 | * |
||
| 12 | * Basically, this consolidates the power off and reboot callbacks |
||
| 13 | * into one structure, as well as adding power management hooks. |
||
| 14 | * |
||
| 15 | * When adding a platform driver, please make sure all callbacks are |
||
| 16 | * filled. There are defaults defined below that do nothing; use those |
||
| 17 | * if you do not support that callback. |
