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 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_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
	help
	  Set VESA/native framebuffer mode (needed for bootsplash and graphical
	  framebuffer console)

choice
	prompt "framebuffer graphics resolution"
	default FRAMEBUFFER_VESA_MODE_117
	depends on FRAMEBUFFER_SET_VESA_MODE
	help
	  This option sets the resolution used for the U-Boot framebuffer (and
	  bootsplash screen).
