This series adds a new uclass for keyboards and converts some drivers over to use it.
This series includes some work to remove code duplication in the keyboard drivers by updating them to use the input library (input.c). This unifies the keycode decoding logic in one place. In order to do this some enhancements are needed to the input library and these are also included.
The cros_ec and tegra_kbc drivers are converted to use driver model.
The i8042 driver is converted also, after various tidy-ups. The driver has some strange interactions with the cfb_console driver. This is removed in this series which is possible because the only user is x86. Some i8042 features have been dropped (the only deliberate one is the flashing cursor which does not seem to be used by any board).
Also the i8042 driver currently has its own keycode decoding logic. This series removes it in favour of the input library. Therefore testing of this new driver would be appreciated. So far I have only been able to test on link, which does not have a full keyboard. Also, while German keyboard support is implemented, I am unable to test that either.
These changes can be considered the first step towards moving stdio to driver model. For that to be useful we need to convert LCD and video also.
Note: This series is missing the code to call the update_leds() method when the LEDs change. This needs to be added to keyboard_tstc() and keyboard_getc(). If someone is able to test this I can send a patch for that also.
