As pointed by Robin as well, as Nvidia hasn't modified ARM MMU-500

Yeah, They are not related. I was trying to use minimum irq entries in the DT
node as they both would achieve the same functionality.

Shouldn't that be 3?
Interrupt line is shared between global and all context faults for each SMMU
instance.
Nvidia implementation checks for both Global and context faults on each
interrupt to an SMMU

It can be either 1 or 3. If we make it
