2 bool "Enable x86 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
10 config VIDEO_LCD_SSD2828
11 bool "SSD2828 bridge chip"
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
19 config VIDEO_LCD_SSD2828_TX_CLK
20 int "SSD2828 TX_CLK frequency (in MHz)"
21 depends on VIDEO_LCD_SSD2828
24 The frequency of the crystal, which is clocking SSD2828. It may be
25 anything in the 8MHz-30MHz range and the exact value should be
26 retrieved from the board schematics. Or in the case of Allwinner
27 hardware, it can be usually found as 'lcd_xtal_freq' variable in
28 FEX files. It can be also set to 0 for selecting PCLK from the
29 parallel LCD interface instead of TX_CLK as the PLL clock source.
31 config VIDEO_LCD_SSD2828_RESET
32 string "RESET pin of SSD2828"
33 depends on VIDEO_LCD_SSD2828
36 The reset pin of SSD2828 chip. This takes a string in the format
37 understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
39 config VIDEO_LCD_HITACHI_TX18D42VM
40 bool "Hitachi tx18d42vm LVDS LCD panel support"
44 Support for Hitachi tx18d42vm LVDS LCD panels, these panels have a
45 lcd controller which needs to be initialized over SPI, once that is
46 done they work like a regular LVDS panel.
48 config VIDEO_LCD_SPI_CS
49 string "SPI CS pin for LCD related config job"
50 depends on VIDEO_LCD_SSD2828 || VIDEO_LCD_HITACHI_TX18D42VM
53 This is one of the SPI communication pins, involved in setting up a
54 working LCD configuration. The exact role of SPI may differ for
55 different hardware setups. The option takes a string in the format
56 understood by 'name_to_gpio' function, e.g. PH1 for pin 1 of port H.
58 config VIDEO_LCD_SPI_SCLK
59 string "SPI SCLK 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_MOSI
69 string "SPI MOSI 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_MISO
79 string "SPI MISO pin for LCD related config job (optional)"
80 depends on VIDEO_LCD_SSD2828
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. If wired up, this pin may provide additional
86 useful functionality. Such as bi-directional communication with the
87 hardware and LCD panel id retrieval (if the panel can report it). The
88 option takes a string in the format understood by 'name_to_gpio'
89 function, e.g. PH1 for pin 1 of port H.
