As result, system will start using default ARM GIC configuration, ignore DT IRQ triggering configuration, and value of desc->irq_data.state_use_accessors = 0. In case of TI OMAP DRA7 the following IRQ hierarchy is defined: ARM GIC <- OMAP wakeupgen <- TI CBAR Failed call chain: irq_create_of_mapping irq_set_irq_type __irq_set_trigger if (!chip || !chip->irq_set_type) { return 0; <- return here } OMAP wakeupgen has no .irq_set_type() defined and, so, IRQ triggering configuration will not be propagated to parent IRQ domain. Hence, fix it by using irq_chip_set_type_parent() for propagation IRQ triggering type to parent IRQ domains.
