* The Matrix Keyboard Protocol driver handles talking to the keyboard
|

* controller chip. Mostly this is for keyboard functions, but some other
|

* things have slipped in, so we provide generic services to talk to the
|
||||
* KBC.
|
||||
* This is the interface to the Chrome OS EC. It provides keyboard functions,
|
||||
* power control and battery management. Quite a few other functions are
|
||||
* provided to enable the EC software to be updated, talk to the EC's I2C bus
|
||||
* and store a small amount of data in a memory which persists while the EC
|
||||
* is not reset.
