Hi Marc, This is continuation of the RFC patches[0] regarding the driver updates to support for following interrupt parent connection: - INTR -> INTR - INTA -> GICv3 The current existing driver assumes that INTR is always connected to GICv3 and INTA is always connected to INTR. As discussed this change breaks the DT backward compatibility but it allows to not depend on TISCI firmware properties in DT node. IMHO, this will ensure that any future changes will not effect DT properties.
