2 * include/linux/platform.h - platform driver definitions
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.
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.
12 * Basically, this consolidates the power off and reboot callbacks
13 * into one structure, as well as adding power management hooks.
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.
