config 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_FONT_4X6
	bool "4 x 6 font size"
	help
	  Font for video console driver, 4 x 6 pixels.
	  Provides character bitmap data in header file.
	  When selecting multiple fonts, you may want to enable CMD_SELECT_FONT too.

config VIDEO_FONT_8X16
	bool "8 x 16 font size"
	default y
	help
	  Font for video console driver, 8 x 16 pixels
	  Provides character bitmap data in header file.
	  When selecting multiple fonts, you may want to enable CMD_SELECT_FONT too.

config VIDEO_LOGO
	bool "Show the U-Boot logo on the display"
	default y if !SPLASH_SCREEN
	select VIDEO_BMP_RLE8
	help
	  This enables showing the U-Boot logo on the display when a video
	  device is probed. It appears at the top right. The logo itself is at
	  tools/logos/u-boot_logo.bmp and looks best when the display has a
	  black background.

config BACKLIGHT
	bool "Enable panel backlight uclass support"
	default y
	help
	  This provides backlight uclass driver that enables basic panel
	  backlight support.

config VIDEO_PCI_DEFAULT_FB_SIZE
	hex "Default framebuffer size to use if no drivers request it"
	default 0x1000000 if X86 && PCI
	default 0 if !(X86 && PCI)
	help
	  Generally, video drivers request the amount of memory they need for
	  the frame buffer when they are bound, by setting the size field in
	  struct video_uc_plat. That memory is then reserved for use after
	  relocation. But PCI drivers cannot be bound before relocation unless
	  they are mentioned in the devicetree.

	  With this value set appropriately, it is possible for PCI video
	  devices to have a framebuffer allocated by U-Boot.

	  Note: the framebuffer needs to be large enough to store all pixels at
	  maximum resolution. For example, at 1920 x 1200 with 32 bits per
	  pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed.

config VIDEO_COPY
	bool "Enable copying the frame buffer to a hardware copy"
	help
	  On some machines (e.g. x86), reading from the frame buffer is very
	  slow because it is uncached. To improve performance, this feature
	  allows the frame buffer to be kept in cached memory (allocated by
	  U-Boot) and then copied to the hardware frame-buffer as needed.

	  To use this, your video driver must set @copy_base in
	  struct video_uc_plat.

config BACKLIGHT_PWM
	bool "Generic PWM based Backlight Driver"
	depends on BACKLIGHT && DM_PWM
	default y
	help
	  If you have a LCD backlight adjustable by PWM, say Y to enable

config BACKLIGHT_GPIO
	bool "Generic GPIO based Backlight Driver"
	depends on BACKLIGHT
	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"
	default y
	help

	  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"
	default y
	help
	  Support drawing text and bitmaps onto a 16-bit-per-pixel display.

	  this option, such displays will not be supported and console output
	  will be empty.

config VIDEO_BPP32
	bool "Support 32-bit-per-pixel displays"
	default y
	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"
	default y if EFI_LOADER
	help
	  Enable ANSI escape sequence decoding for a more fully functional
	  console. Functionality includes changing the text colour and moving
	  the cursor. These date from the 1970s and are still widely used today
	  to control a text terminal. U-Boot implements these by decoding the
	  sequences and performing the appropriate operation.

config VIDEO_MIPI_DSI
	bool "Support MIPI DSI interface"
	help
	  Support MIPI DSI interface for driving a MIPI compatible device.
	  The MIPI Display Serial Interface (MIPI DSI) defines a high-speed
	  serial interface between a host processor and a display module.

config CONSOLE_NORMAL
	bool "Support a simple text console"
	default y
	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"
	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"
	select CMD_SELECT_FONT
	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 CONSOLE_TRUETYPE_MAX_METRICS
	int "TrueType maximum number of font / size combinations"
	depends on CONSOLE_TRUETYPE
	default 10 if EXPO
	default 1
	help
	  This sets the number of font / size combinations which can be used by
	  the console. For simple console use a single font is enough. When
	  boot menus are in use, this may need to be increased.

	  Note that a separate entry is needed for each font size, even if the
	  font itself is the same. This is because the entry caches various
	  font metrics which are expensive to regenerate each time the font
	  size changes.

config SYS_WHITE_ON_BLACK
	bool "Display console as white on a black background"
	default y if ARCH_AT91 || ARCH_EXYNOS || ARCH_ROCKCHIP || ARCH_TEGRA || X86 || ARCH_SUNXI
	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 PANEL
	bool "Enable panel uclass support"
	default y
	help
	  This provides panel uclass driver that enables basic panel support.

config SIMPLE_PANEL
	bool "Enable simple panel support"
	depends on PANEL && BACKLIGHT && DM_GPIO
	default y
	help
	  This turns on a simple panel driver that enables a compatible
	  video panel.

config PANEL_HX8238D
	bool "Enable Himax HX-8238D LCD driver"
	depends on PANEL
	help
	  Support for HX-8238D LCD Panel
	  The  HX8238-D is a single chip controller and driver LSI that
	  integrates the power circuit.
	  It can drive a maximum 960x240 dot graphics on a-TFT panel

	  This is a work-around for boards which have 'lcd' or 'vga' 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 2020.

	depends on X86
	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

	  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"
	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 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

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"

	  Enable support for the gdsys Integrated Hardware Systems (IHS) video
	  out On-screen Display (OSD) used on gdsys FPGAs to control dynamic
	  textual overlays of the display outputs.

config SPLASH_SCREEN
	bool "Show a splash-screen image"
	help
	  If this option is set, the environment is checked for a variable
	  "splashimage". If found, the usual display of logo, copyright and
	  system information on the LCD is suppressed and the BMP image at the
	  address specified in "splashimage" is loaded instead. The console is
	  redirected to the "nulldev", too. This allows for a "silent" boot
	  where a splash screen is loaded very quickly after power-on.

	  The splash_screen_prepare() function is a weak function defined in
	  common/splash.c. It is called as part of the splash screen display
	  sequence. It gives the board an opportunity to prepare the splash
	  image data before it is processed and sent to the frame buffer by
	  U-Boot. Define your own version to use this feature.

if SPLASH_SCREEN

config SPLASH_SCREEN_ALIGN
	bool "Allow positioning the splash image anywhere on the display"
	help
	  If this option is set the splash image can be freely positioned
	  on the screen. Environment variable "splashpos" specifies the
	  position as "x,y". If a positive number is given it is used as
	  number of pixel from left/top. If a negative number is given it
	  is used as number of pixel from right/bottom. You can also
	  specify 'm' for centering the image.

	  Example:
	  setenv splashpos m,m
	  	=> image at center of screen

	  setenv splashpos 30,20
	  	=> image at x = 30 and y = 20

	  setenv splashpos -10,m
	  	=> vertically centered image
	  	   at x = dspWidth - bmpWidth - 9

config HIDE_LOGO_VERSION
	bool "Hide the version information on the splash screen"
	help
	  Normally the U-Boot version string is shown on the display when the
	  splash screen is enabled. This information is not otherwise visible
	  since video starts up after U-Boot has displayed the initial banner.

	  Enable this option to hide this information.

config SPLASH_SOURCE
	bool "Control the source of the splash image"
	help
	  Use the splash_source.c library. This library provides facilities to
	  declare board specific splash image locations, routines for loading
	  splash image from supported locations, and a way of controlling the
	  selected splash location using the "splashsource" environment
	  variable.

	  This CONFIG works as follows:

	  - If splashsource is set to a supported location name as defined by
	    board code, use that splash location.
	  - If splashsource is undefined, use the first splash location as
	    default.
	  - If splashsource is set to an unsupported value, do not load a splash
	    screen.

	  A splash source location can describe either storage with raw data, a
	  storage formatted with a file system or a FIT image. In case of a
	  filesystem, the splash screen data is loaded as a file. The name of
	  the splash screen file can be controlled with the environment variable
	  "splashfile".

	  To enable loading the splash image from a FIT image, CONFIG_FIT must
	  be enabled. The FIT image has to start at the 'offset' field address
	  in the selected splash location. The name of splash image within the
	  FIT shall be specified by the environment variable "splashfile".

	  In case the environment variable "splashfile" is not defined the
	  default name 'splash.bmp' will be used.

	depends on CMD_BMP || SPLASH_SCREEN
	help
	  If this option is set, additionally to standard BMP

config VIDEO_LOGO_MAX_SIZE
	hex "Maximum size of the bitmap logo in bytes"
	default 0x100000
	help
	  Sets the maximum uncompressed size of the logo. This is needed when
	  decompressing a BMP file using the gzip algorithm, since it cannot
	  read the size from the bitmap header.
