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 VIDEO_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 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)

	  bootsplash screen).

	The frequency of the crystal, which is clocking SSD2828. It may be
	anything in the 8MHz-30MHz range and the exact value should be
	retrieved from the board schematics. Or in the case of Allwinner
	hardware, it can be usually found as 'lcd_xtal_freq' variable in
	FEX files. It can be also set to 0 for selecting PCLK from the
	parallel LCD interface instead of TX_CLK as the PLL clock source.
