2 bool "Enable VESA video driver support"
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. This can in principle be used with any platform that
9 supports PCI and video cards that support VESA BIOS Extension (VBE).
12 bool "Enable x86 video driver support"
16 Turn on this option to enable a very simple driver which uses vesa
17 to discover the video mode and then provides a frame buffer for use
20 config VIDEO_LCD_SSD2828
21 bool "SSD2828 bridge chip"
24 Support for the SSD2828 bridge chip, which can take pixel data coming
25 from a parallel LCD interface and translate it on the fly into MIPI DSI
26 interface for driving a MIPI compatible LCD panel. It uses SPI for
29 config VIDEO_LCD_SSD2828_TX_CLK
30 int "SSD2828 TX_CLK frequency (in MHz)"
31 depends on VIDEO_LCD_SSD2828
34 The frequency of the crystal, which is clocking SSD2828. It may be
35 anything in the 8MHz-30MHz range and the exact value should be
36 retrieved from the board schematics. Or in the case of Allwinner
37 hardware, it can be usually found as 'lcd_xtal_freq' variable in
38 FEX files. It can be also set to 0 for selecting PCLK from the
39 parallel LCD interface instead of TX_CLK as the PLL clock source.
41 config VIDEO_LCD_SSD2828_RESET
42 string "RESET pin of SSD2828"
43 depends on VIDEO_LCD_SSD2828
46 The reset pin of SSD2828 chip. This takes a string in the format
47 understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
49 config VIDEO_LCD_HITACHI_TX18D42VM
50 bool "Hitachi tx18d42vm LVDS LCD panel support"
54 Support for Hitachi tx18d42vm LVDS LCD panels, these panels have a
55 lcd controller which needs to be initialized over SPI, once that is
56 done they work like a regular LVDS panel.
58 config VIDEO_LCD_SPI_CS
59 string "SPI CS pin for LCD related config job"
60 depends on VIDEO_LCD_SSD2828 || VIDEO_LCD_HITACHI_TX18D42VM
63 This is one of the SPI communication pins, involved in setting up a
64 working LCD configuration. The exact role of SPI may differ for
65 different hardware setups. The option takes a string in the format
66 understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
68 config VIDEO_LCD_SPI_SCLK
69 string "SPI SCLK pin for LCD related config job"
70 depends on VIDEO_LCD_SSD2828 || VIDEO_LCD_HITACHI_TX18D42VM
73 This is one of the SPI communication pins, involved in setting up a
74 working LCD configuration. The exact role of SPI may differ for
75 different hardware setups. The option takes a string in the format
76 understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
78 config VIDEO_LCD_SPI_MOSI
79 string "SPI MOSI pin for LCD related config job"
80 depends on VIDEO_LCD_SSD2828 || VIDEO_LCD_HITACHI_TX18D42VM
83 This is one of the SPI communication pins, involved in setting up a
84 working LCD configuration. The exact role of SPI may differ for
85 different hardware setups. The option takes a string in the format
86 understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
88 config VIDEO_LCD_SPI_MISO
89 string "SPI MISO pin for LCD related config job (optional)"
90 depends on VIDEO_LCD_SSD2828
93 This is one of the SPI communication pins, involved in setting up a
94 working LCD configuration. The exact role of SPI may differ for
95 different hardware setups. If wired up, this pin may provide additional
96 useful functionality. Such as bi-directional communication with the
97 hardware and LCD panel id retrieval (if the panel can report it). The
98 option takes a string in the format understood by 'name_to_gpio'
99 function, e.g. PH1 for pin 1 of port H.
