[PATCH v2 00/16] MIPS: GIC device-tree support

[Andrew Bresticker <abrestic@chromium.org>]

This series add support for mapping and routing GIC interrupts through
the device-tree, which will be used on the upcoming interAptiv-based
Danube SoC.

- Patches 1 and 2 provide improvements to the CPU interrupt controller
  when used with DT.
- Patch 3 exports the MIPS CPU IRQ domain so that the GIC driver can
  use it.
- Patch 4 is a fix for secondary CPU bringup with CPS.
- Patches 5 through 9 are misc. GIC cleanups, including moving the GIC
  driver to drivers/irqchip/.
- Patches 10 through 13 add device-tree support for the GIC.
- Patches 14 through 16 cleanup/fix GIC local interrupt support.

Based on 3.17-rc3 and boot tested on Danube (+ out of tree patches) and
Malta.  Build tested for SEAD-3.  Paul Burton has also tested v1 of this
series with his WIP Malta DT support [0].

Changes from v1:
 - updated bindings to drop third interrupt cell and remove CPU interrupt
   controller as the parent of the GIC
 - moved GIC to drivers/irqchip/
 - other minor fixes/cleanups
