[U-Boot] [PATCH 00/18] dm: video: Introduce initial driver-model video support

[Simon Glass]

This series starts the process of converting LCD and video devices over to
use driver model. Both now use a very similar API thanks to earlier work by
Nikita Kiryanov. With the driver-model conversion these will end up unified
in a single uclass.

Unfortunately there are different features supported by each. This
implementation provides for a common set of features which should serve
most purposes. The intent is to support:

- bitmap devices with 8, 16 and 32 bits per pixel
- text console wih white on black or vice versa
- rotated text console
- bitmap display (BMP format)

More can be added as additional boards are ported over to use driver model
for video.

The name 'video' is chosen for the uclass since it is more generic than LCD.
Another option would be 'display' but that would introduce a third concept
to U-Boot which seems like the wrong approach.

The existing LCD and video init functions are not needed now, so this uclass
does not implement them. This includes lcd_ctrl_init(), lcd_enable() and
video_init().

Tests are provided to check that console text and bitmap output is correct.
These should be able to be extended as more features are added.

Future work will convert a few boards over to use driver model for video.
Likely targets are x86, exynos, tegra. Also, Rockchip LCD support will be
added using driver model (patches will likely be sent some time in January).
