# # Video configuration # menu "Graphics support" 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 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 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 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 help Enable ANSI escape sequence decoding for a more fully functional console. config VIDEO_MIPI_DSI bool "Support MIPI DSI interface" depends on DM_VIDEO 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" 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 || 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. source "drivers/video/fonts/Kconfig" 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.
