Subject: [Patch v7 1/7] microblaze: irqchip: Move intc driver to irqchip
Date: Mon, 14 Nov 2016 12:13:45 +0000	[thread overview]
Message-ID: <20161114121351.10924-2-Zubair.Kakakhel@imgtec.com> (raw)
In-Reply-To: <20161114121351.10924-1-Zubair.Kakakhel@imgtec.com>

The Xilinx AXI Interrupt Controller IP block is used by the MIPS
based xilfpga platform and a few PowerPC based platforms.

Move the interrupt controller code out of arch/microblaze so that
it can be used by everyone

Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com>

---
V6 -> V7
Rebase to v4.9-rc5

V5 -> V6
Rebase to v4.9-rc3

V4 -> V5
Rebase to v4.9-rc1
Renamed back to irq-xilinx-intc.c

V3 -> V4
No change

V2 -> V3
No change here. Cleanup patches follow after this patch.
Its debatable to cleanup before/after move. Decided to place cleanup
after move to put history in new place.

V1 -> V2

Renamed irq-xilinx to irq-axi-intc
Renamed CONFIG_XILINX_INTC to CONFIG_XILINX_AXI_INTC
Patch is now without rename flag so as to facilitate review
