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 BACKLIGHT_PWM
	bool "Generic PWM based Backlight Driver"
	depends on DM_VIDEO && DM_PWM
	default y
	help
	  If you have a LCD backlight adjustable by PWM, say Y to enable
	  this driver.
	  This driver can be use with "simple-panel" and
	  it understands the standard device tree
	  (leds/backlight/pwm-backlight.txt)

config BACKLIGHT_GPIO
	bool "Generic GPIO based Backlight Driver"
	depends on DM_VIDEO
	help
	  If you have a LCD backlight adjustable by GPIO, say Y to enable
	  this driver.
	  This driver can be used with "simple-panel" and
	  it understands the standard device tree
	  (leds/backlight/gpio-backlight.txt)

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 VIDEO_ANSI
	bool "Support ANSI escape sequences in video console"
	depends on DM_VIDEO
	default y if DM_VIDEO
	help
	  Enable ANSI escape sequence decoding for a more fully functional
	  console.

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 NO_FB_CLEAR
	bool "Skip framebuffer clear"
	help
	  If firmware (whatever loads u-boot) has already put a splash image
	  on screen, you might want to preserve it until whatever u-boot
	  loads takes over the screen.  This, for example, can be used to
	  keep splash image on screen until grub graphical boot menu starts.

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_EFI
	bool "Enable EFI framebuffer driver support"
	depends on EFI_STUB
	help
	  Turn on this option to enable a framebuffeer driver when U-Boot is
	  loaded as a payload (see README.u-boot_on_efi) by an EFI BIOS where
	  the graphics device is configured by the EFI BIOS already. This can
	  in principle be used with any platform that has an EFI BIOS.

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).

config FRAMEBUFFER_SET_VESA_MODE
	bool "Set framebuffer graphics resolution"
	depends on VIDEO_VESA || VIDEO_BROADWELL_IGD
	help
	  Set VESA/native framebuffer mode (needed for bootsplash and graphical
	  framebuffer console)

	  Defines the foreground colour for the console. The value is from
	  0x00 to 0xff and the meaning depends on the graphics card.
	  Typically, 0x00 means black and 0xff means white. Do not set
	  the background and foreground to the same colour or you will see

config LCD
	bool "Enable legacy LCD support"
	help
	  Define this to enable LCD support (for output to LCD display).
	  You will also need to select an LCD driver using an additional
	  CONFIG option. See the README for details. Drives which have been
	  converted to driver model will instead used CONFIG_DM_VIDEO.

config VIDEO_DW_HDMI
	bool
	help
	  Enables the common driver code for the Designware HDMI TX
	  block found in SoCs from various vendors.
	  As this does not provide any functionality by itself (but
	  rather requires a SoC-specific glue driver to call it), it
	  can not be enabled from the configuration menu.

config VIDEO_SIMPLE
	bool "Simple display driver for preconfigured display"
	help
	  Enables a simple generic display driver which utilizes the
	  simple-framebuffer devicetree bindings.

	  This driver assumes that the display hardware has been initialized
	  before u-boot starts, and u-boot will simply render to the pre-
	  allocated frame buffer surface.

config VIDEO_DT_SIMPLEFB
	bool "Enable SimpleFB support for passing framebuffer to OS"
	help
	  Enables the code to pass the framebuffer to the kernel as a
	  simple framebuffer in the device tree.
	  The video output is initialized by U-Boot, and kept by the
	  kernel.

config OSD
	bool "Enable OSD support"
	depends on DM
	default n
	help
	   This supports drivers that provide a OSD (on-screen display), which
	   is a (usually text-oriented) graphics buffer to show information on
	   a display.

config SANDBOX_OSD
	bool "Enable sandbox OSD"
	depends on OSD
	help
	  Enable support for sandbox OSD device used for testing purposes.

config IHS_VIDEO_OUT
	bool "Enable IHS video out driver"
	depends on OSD
	help

	  out On-screen Display (OSD) used on gdsys FPGAs to control dynamic
