Module Name: src
Committed By: bouyer
Date: Sun Nov 15 21:28:54 UTC 2015
Modified Files:
src/sys/arch/arm/allwinner: awin_hdmi.c awin_reg.h awin_tcon.c
awin_var.h
src/sys/arch/evbarm/awin: awin_machdep.c
Log Message:
Add support for LVDS output on tcon0. Tested with a full HD LVDS display.
Other LCD interfaces not supported yet, mostly by lack of hardware.
The LVDS output and timings are set from the FEX script.
