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 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 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_HITACHI_TX18D42VM bool "Hitachi tx18d42vm LVDS LCD panel support" depends on VIDEO default n ---help--- Support for Hitachi tx18d42vm LVDS LCD panels, these panels have a lcd controller which needs to be initialized over SPI, once that is done they work like a regular LVDS panel. config VIDEO_LCD_SPI_CS string "SPI CS pin for LCD related config job" depends on VIDEO_LCD_SSD2828 || VIDEO_LCD_HITACHI_TX18D42VM 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 || VIDEO_LCD_HITACHI_TX18D42VM 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 || VIDEO_LCD_HITACHI_TX18D42VM 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.
