8de536c27c video: sandbox: Allow selection of font size and console name
For testing it is useful to be able to select the font size and the console
driver for sandbox. Add this information to platform data and copy it to
the video device when needed.

826f35f9b5 video: Allow selection of the driver and font size
Provide a way for the video console driver to be selected. This is
controlled by the video driver's private data. This can be set up when the
driver is probed so that it is ready for the video_post_probe() method.

The font size is provided as well. The console driver may or may not support
this depending on its capability.

a29b012037 video: Add a console driver that uses TrueType fonts
The existing 8x16 font is adequate for most purposes. It is small and fast.
However for boot screens where information must be presented to the user,
the console font is not ideal. Common requirements are larger and
better-looking fonts.

This console driver can use TrueType fonts built into U-Boot, and render
them at any size. This can be used in scripts to place text as needed on
the display.

This driver is not really designed to operate with the command line. Much
of U-Boot expects a fixed-width font. But to keep things working correctly,
rudimentary support for the console is provided. The main missing feature is
support for command-line editing.

f266178698 video: Use fractional units for X coordinates
With anti-aliased fonts we need a more fine-grained horizontal position
than a single pixel. Characters can be positioned to start part-way through
a pixel, with anti-aliasing (greyscale edges) taking care of the visual
effect.

To cope with this, use fractional units (1/256 pixel) for horizontal
positions in the text console.

8340ef6278 video: Add stb TrueType font renderer
This is a header file which provides a fairly light-weight TrueType
rendering implementation. It is pulled from http://nothings.org/. The code
style does not comply with U-Boot but I think it is best to leave alone to
permit the source to be synced later if needed.

The only change is to fix a reference to fabs() which should route through
a macro to allow U-Boot to provide its own version.

Some Rockchip SoCs support HDMI output. Add a display driver for this so
that these displays can be used on supported boards.

Unfortunately this driver is not fully functional. It cannot reliably read
EDID information over HDMI. This seems to be due to the clocks being
incorrect - the I2C bus speed appears to be up to 100x slower than the
clock settings indicate. The root cause may be in the clock logic.

1acafc73bf dm: video: Add a video uclass
U-Boot has separate code for LCDs and 'video' devices. Both now use a
very similar API thanks to earlier work by Nikita Kiryanov. With the driver-
model conversion we should unify these into 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
makes no attempt to implement them.

7fe0933c58 video: Drop unused console functions
CONFIG_CONSOLE_CURSOR, CONFIG_SYS_CONSOLE_BLINK_COUNT and
CONFIG_CONSOLE_TIME are not used by any board. The implementation is not
great and stands in the way of a refactor of i8042. Drop these for now.
They can be re-introduced quite easily later, perhaps with driver-model
real-time-clock (RTC) support.

When reintroducing, it might be useful to make a few changes:
- Blink time would be more useful than blink count
- The confusing #ifdefs should be avoided
- The time functions should support driver model
- It would be best keyed off console_tstc() or some similar idle loop
    rather than a particular input driver (i8042 in this case)

Introudce a new function lcdif_power_down.

1. Waits for a VSYNC interrupt to guarantee the reset is done at the

   and helps the LCDIF work normally at the kernel stage.
2. Add power down function to stop lcdif.

The reason to introduce lcdif_power_down is that we want lcdif to be in
initial state when doing uboot reset or before kernel boot to make
system stable, otherwise system may hang.
