reserved-interrupts =3D <2>;I'm currious about the above though, what is it ?Quote from the CHRP ISA interrupt controller device binding document: =93reserved-interrupts=94 Standard property name to define reserved interrupts. prop-encoded-array: An integer array, encoded with encode-int. The value of this property shall be a list of ISA interrupts which=20 cannot be assigned due to cascading, wiring, or other reasons. Only the irq#=20=
part of the property is pertinent to this use.
I never found any situation where this property is useful (you need a lot more information to do anything but static IRQ routing on ISA anyway), but it doesn't harm anything either. Segher
