/*
 * 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.
