config VIDEO_VESA

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. This can in principle be used with any platform that
|
|
supports PCI and video cards that support VESA BIOS Extension (VBE).

|
|
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.

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.

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.
