[U-Boot] [PATCH v3 00/12] dm: input: Move keyboard drivers to driver model

[Simon Glass]

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.

This series is available at u-boot-dm branch input-working.

Changes in v3:
- Refactor the German keyboard code to use data rather than code
- Drop unrelated cros_keyb change
- Fix 'QUICK' typo
- Fix missing 'use' word
- Drop patches already applied

Changes in v2:
- Update input_add_tables() to add error checking
- Convert two multi-line comments to single-line comments
- Correct call to input_init()
- Drop CONFIG_VGA_AS_SINGLE_DEVICE from all x86 board config files
- Use device tree to handle this quirk
