- /*
- * 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.
