MPIC on NXP (Freescale) P2020 supports following irq ranges: > 0 - 11 (External interrupt) > 16 - 79 (Internal interrupt) > 176 - 183 (Messaging interrupt) > 224 - 231 (Shared message signaled interrupt)
We have to remove "irq_count" from platform code as platform is given precedence over device-tree, while I think device-tree should have precedence.
