Subject: [Patch v5 00/12] microblaze/MIPS/PowerPC: Xilinx intc

Hi,

The MIPS based Xilfpga platform uses the axi interrupt controller
daisy chained to the MIPS microAptiv cpu interrupt controller.
This patch series moves the axi interrupt controller driver out
of arch/microblaze to drivers/irqchip and then cleans it up a bit.
And then remove another implementation of the driver in arch/powerpc.
This makes one common driver usable by mips,microblaze and powerpc.
The rest of the series basically enables drivers and adds dt nodes.

Would make sense for this to go via the MIPS tree.
Hence, ACKs from microblaze, powerpc and irqchip welcome.

Compile tested on microblaze-el.
Tested using qemu-system-ppc using virtix440-ml507

Based on v4.9-rc1

Regards,
ZubairLK

V4 -> V5
Added a new patch that removes the PPC driver
Rebase to v4.9-rc1
Better error handling

V3 -> V4
Better error handling
Some minor fixups

V2 -> V3
Cleanup the interrupt controller driver a bit based on feedback
Rebase to v4.8-rc4

V1 -> V2
Resubmitting without truncating the diff output for file moves
Removed accidental local mac address entry
Individual logs have more detail
