523What: corgikbd, spitzkbd, tosakbd driver
524When: 2.6.35
525Files: drivers/input/keyboard/{corgi,spitz,tosa}kbd.c
526Why: We now have a generic GPIO based matrix keyboard driver that
527 are fully capable of handling all the keys on these devices.
528 The original drivers manipulate the GPIO registers directly
529 and so are difficult to maintain.
