From: Linus Walleij <linus.walleij@linaro.org>
Since in the DT case, the linear domain path will not allocate descriptors for the IRQs, we need to use irq_create_mapping() for mapping hwirqs to Linux IRQs, so these descriptors get created on-the-fly in this case.
ChangeLog v1->v2:
- Just use irq_create_mapping() in the .to_irq function since this is called before unmasking or enabling any interrupt lines, so irq_find_mapping() should be sufficient for the IRQ handler function.
