config VIDEO_X86
bool "Enable x86 video driver support"
depends on X86
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.
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
interface for driving a MIPI compatible LCD panel. It uses SPI for
configuration.
config VIDEO_LCD_SSD2828_TX_CLK
int "SSD2828 TX_CLK frequency (in MHz)"
depends on VIDEO_LCD_SSD2828
---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.
config VIDEO_LCD_SSD2828_RESET
string "RESET pin of SSD2828"
depends on VIDEO_LCD_SSD2828
default ""
---help---
The reset pin of SSD2828 chip. This takes a string in the format
understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
config VIDEO_LCD_SPI_CS
string "SPI CS pin for LCD related config job"
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. The option takes a string in the format
understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
config VIDEO_LCD_SPI_SCLK
string "SPI SCLK pin for LCD related config job"
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. The option takes a string in the format
understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
config VIDEO_LCD_SPI_MOSI
string "SPI MOSI pin for LCD related config job"
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. The option takes a string in the format
understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
config VIDEO_LCD_SPI_MISO
string "SPI MISO pin for LCD related config job (optional)"
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.
