Philipp Tomsich 8517f64fe6 rockchip: video: introduce VIDEO_DW_HDMI and select for Rockchip HDMI 
Instead of having drivers/video/rockchip/Kconfig point outside of its
hierarchy for dw_hdmi.o, we should use a configuration-option to
include the Designware HDMI support.

This change introduces a new config option (not to be selected via
menuconfig, but to be selected from a dependent video driver's
configuration option) that enables dw_hdmi.o and selects it whenever
the HDMI support for Rockchip SoCs is selected.

config DM_VIDEO
bool "Enable driver model support for LCD/video"
depends on DM
help
This enables driver model for LCD and video devices. These support
a bitmap display of various sizes and depths which can be drawn on
to display a command-line console or splash screen. Enabling this
option compiles in the video uclass and routes all LCD/video access
through this.
config VIDEO_BPP8
bool "Support 8-bit-per-pixel displays"
depends on DM_VIDEO
default y if DM_VIDEO
help
Support drawing text and bitmaps onto a 8-bit-per-pixel display.
Enabling this will include code to support this display. Without
this option, such displays will not be supported and console output
will be empty.
config VIDEO_BPP16
bool "Support 16-bit-per-pixel displays"
depends on DM_VIDEO
default y if DM_VIDEO
help
Support drawing text and bitmaps onto a 16-bit-per-pixel display.
Enabling this will include code to support this display. Without
this option, such displays will not be supported and console output
will be empty.
config VIDEO_BPP32
bool "Support 32-bit-per-pixel displays"
depends on DM_VIDEO
default y if DM_VIDEO
help
Support drawing text and bitmaps onto a 32-bit-per-pixel display.
Enabling this will include code to support this display. Without
this option, such displays will not be supported and console output
will be empty.
config CONSOLE_NORMAL
bool "Support a simple text console"
depends on DM_VIDEO
default y if DM_VIDEO
help
Support drawing text on the frame buffer console so that it can be
used as a console. Rotation is not supported by this driver (see
CONFIG_CONSOLE_ROTATION for that). A built-in 8x16 font is used
for the display.
config CONSOLE_ROTATION
bool "Support rotated displays"
depends on DM_VIDEO
help
Sometimes, for example if the display is mounted in portrait
mode or even if it's mounted landscape but rotated by 180degree,
we need to rotate our content of the display relative to the
framebuffer, so that user can read the messages which are
printed out. Enable this option to include a text driver which can
support this. The rotation is set by the 'rot' parameter in
struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180
degrees, 3=270 degrees.
config CONSOLE_TRUETYPE
bool "Support a console that uses TrueType fonts"
depends on DM_VIDEO
help
TrueTrype fonts can provide outline-drawing capability rather than
needing to provide a bitmap for each font and size that is needed.
With this option you can adjust the text size and use a variety of
fonts. Note that this is noticeably slower than with normal console.
config CONSOLE_TRUETYPE_SIZE
int "TrueType font size"
depends on CONSOLE_TRUETYPE
default 18
help
This sets the font size for the console. The size is measured in
pixels and is the nominal height of a character. Note that fonts
are commonly measured in 'points', being 1/72 inch (about 3.52mm).
However that measurement depends on the size of your display and
there is no standard display density. At present there is not a
method to select the display's physical size, which would allow
U-Boot to calculate the correct font size.
config SYS_WHITE_ON_BLACK
bool "Display console as white on a black background"
default y if ARCH_AT91 || ARCH_EXYNOS || ARCH_ROCKCHIP || TEGRA || X86
help
Normally the display is black on a white background, Enable this
option to invert this, i.e. white on a black background. This can be
better in low-light situations or to reduce eye strain in some
cases.

config VIDCONSOLE_AS_LCD
bool "Use 'vidconsole' when 'lcd' is seen in stdout"
depends on DM_VIDEO
help
This is a work-around for boards which have 'lcd' in their stdout
environment variable, but have moved to use driver model for video.
In this case the console will no-longer work. While it is possible
to update the environment, the breakage may be confusing for users.
This option will be removed around the end of 2016.
config VIDEO_COREBOOT
bool "Enable coreboot framebuffer driver support"
depends on X86 && SYS_COREBOOT
help
Turn on this option to enable a framebuffer driver when U-Boot is
loaded by coreboot where the graphics device is configured by
coreboot already. This can in principle be used with any platform
that coreboot supports.
config VIDEO_VESA
bool "Enable VESA video driver support"
default n
help
Turn on this option to enable a very simple driver which uses vesa
to discover the video mode and then provides a frame buffer for use
by U-Boot. This can in principle be used with any platform that
supports PCI and video cards that support VESA BIOS Extension (VBE).
