[PATCH 0/4] PCI: mvebu: Add support for error interrupt

["Pali Rohár" <pali@kernel.org>]

PCI mvebu error interrupt source is triggered for non-INTx event.
So e.g. when AER or PME event occurs.

This patch series adds support for reporting AER and PME interrupts on
Marvell PCIe Root Ports which allows use to kernel AER and PME drivers.

Without this change kernel AER and PME drivers do not work at all.

DT bindings for this support is currently provided only for Kirkwood and
Dove platforms as other new mvebu SoCs requires extension to armada IRQ
driver, which is currently disallowed.

Without new DTS files, pci-mvebu.c driver acts as before this change,
there is no AER and PME kernel support.

I have tested this change on Armada 385 board (with additional changes
to A385 DTS files and IRQ driver, not included there) and AER interrupt
is delivered to kernel AER driver correctly.
