Snapshot of work in progress on support for multiple display outputs.
The display configuration comes from the fex script as defined in http://linux-sunxi.org/Fex_Guide, section disp_init. There is some code to convert lcd0_para/lcd1_para to properties but it's not used yet. At this time only mode 0 (debe0->tcon0->hdmi) works. debe0->tcon1->hdmi and debe1->tcon0->hdmi both gives a valid HDMI signal but completely blank screen. AWIN_TCON1_BLUEDATA gives a blue screen in both cases so tcon1->hdmi works. I suspect that, for some reason setups other than debe0->tcon0 are not configured properly, and the tcon is reading all-1 bits instead of the expected debe output.
