Changes in v2 Russell indicated that there could be an on chip inteverter on some interrupt lines and hence there is no way to enforce correct edge rising/falling or level high/low configuration. The change to introduce set_type callback is dropped. Also the change to configure SPI's and PPI's as level/edge depending on the flow_type argument passed in gic_dist_init is dropped. As per Catalin's suggestion all the interrupts reported by gic are disabled. This way we initialize and disable all the unused interrupts. The iterator,i in the gic_dist_init is still prevented from exceeding NR_IRQS. As per Ben Dook's suggestion 'gic:...' is changed to 'GIC:...' in title. Thanks for all your inputs. Please let me know if further changes are required.
