1config VIDEO_X86 2 bool "Enable x86 video driver support" 3 depends on X86 4 default n 5 help 6 Turn on this option to enable a very simple driver which uses vesa 7 to discover the video mode and then provides a frame buffer for use 8 by U-Boot. 9 10config VIDEO_LCD_SSD2828 11 bool "SSD2828 bridge chip" 12 default n 13 ---help--- 14 Support for the SSD2828 bridge chip, which can take pixel data coming 15 from a parallel LCD interface and translate it on the fly into MIPI DSI 16 interface for driving a MIPI compatible LCD panel. It uses SPI for 17 configuration. 18 19config VIDEO_LCD_SSD2828_TX_CLK 20 int "SSD2828 TX_CLK frequency (in MHz)" 21 depends on VIDEO_LCD_SSD2828 22 ---help--- 23 The frequency of the crystal, which is clocking SSD2828. It may be 24 anything in the 8MHz-30MHz range and the exact value should be 25 retrieved from the board schematics. Or in the case of Allwinner 26 hardware, it can be usually found as 'lcd_xtal_freq' variable in 27 FEX files. 28 29config VIDEO_LCD_SSD2828_RESET 30 string "RESET pin of SSD2828" 31 depends on VIDEO_LCD_SSD2828 32 default "" 33 ---help--- 34 The reset pin of SSD2828 chip.
