From: Linus Walleij <linus.wall...@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.
