the differences.
Our driver writer's code isn't functioning, but it was with 2.6.10 and
planet core. The best I can tell is that the default interrupt
controller configuration isn't where it was in the planetcore/2.6.10
version.
for example, let's look at enabling timer1 / interrupt number 12
simple description.
timer1 {
name = "timer1";
compatible = "fsl,mpc8248_timer";

interrupt-parent = <&PIC>;Device tree nodes should really describe an actual device, not just some random floating interrupt. You need to work out what device this interrupt actually belongs to, and describe that. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
