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.

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.

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
Siarhei Siamashka61fb91f2015-01-19 05:23:35 +020028 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.
