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. | ||
