I'm try to securing LCD on L4 Linux using Freescale i.MX6Q SABRESD board. I succeeded in securing Ethernet on L4 Linux. But I don't yet secure LCD on L4 Linux.

LCD(HSD100PXN1) is connected by LVDS. I've modified as below..

1.' .io' I've added LDB control register address to '.io' file.

2. 'mach_setup.c'

(l4linux/arch/l4/kernel/arch-arm/mach_setup.c) I've added code for LVDS.

Qusetion 1. Did I do wrong modification ?

Looks good but probably just a start.

Qusetion 2. Must I do something outside of that ?

At least you also need to enable the driver but I guess you did that? So assuming the driver is trying to start up, where is it bailing out before successfully completing?
