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

framebuffer console)

help
This option sets the resolution used for the U-Boot framebuffer (and
bootsplash screen).

---help---
Support for the ANX9804 bridge chip, which can take pixel data coming
from a parallel LCD interface and translate it on the fy into a DP
interface for driving eDP TFT displays. It uses I2C for configuration.
config VIDEO_LCD_SSD2828
bool "SSD2828 bridge chip"
default n
---help---
Support for the SSD2828 bridge chip, which can take pixel data coming
from a parallel LCD interface and translate it on the fly into MIPI DSI

configuration.
config VIDEO_LCD_SSD2828_TX_CLK
int "SSD2828 TX_CLK frequency (in MHz)"
depends on VIDEO_LCD_SSD2828
default 0
---help---
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.
config VIDEO_LCD_SSD2828_RESET
string "RESET pin of SSD2828"
depends on VIDEO_LCD_SSD2828

depends on VIDEO_LCD_SSD2828
default ""
---help---
This is one of the SPI communication pins, involved in setting up a
working LCD configuration. The exact role of SPI may differ for
different hardware setups. If wired up, this pin may provide additional
useful functionality. Such as bi-directional communication with the
hardware and LCD panel id retrieval (if the panel can report it). The
option takes a string in the format understood by 'name_to_gpio'
function, e.g. PH1 for pin 1 of port H.
config DISPLAY_PORT

eDP (Embedded DisplayPort) is a standard widely used in laptops
to drive LCD panels. This framework provides support for enabling
these displays where supported by the video hardware.
config VIDEO_SANDBOX_SDL
bool "Enable sandbox video console using SDL"
depends on SANDBOX
help
When using sandbox you can enable an emulated LCD display which
appears as an SDL (Simple DirectMedia Layer) window. This is a
console device and can display stdout output. Within U-Boot is is
a normal bitmap display and can display images as well as text.
config VIDEO_TEGRA124
bool "Enable video support on Tegra124"
