Test on magician (nonvanilla, but there should not be any collision).

Fails around here with:
[ 4245.368764] pxa2xx-ir pxa2xx-ir: invalid resource
[ 4245.369191] pxa2xx-ir pxa2xx-ir: resource ficp not defined
[ 4245.369364] pxa2xx-ir: probe of pxa2xx-ir failed with error -22
Did you defined resources somewhere? Actual resources are in "pxa_ir_resources"
variable at:
http://lxr.free-electrons.com/source/arch/arm/mach-pxa/devices.c#L386
or this pdata should be moved into specific machine files?
Cheers,
Petr
