[PATCH v11 0/3]add PCIe driver for Kirin PCIe

[Bjorn Helgaas]

[+cc Catalin, Will, linux-arm-kernel]

Applied patches 2 & 3 to pci/host-kirin for v4.13.

I would like a MAINTAINERS update, too.  If you send me that, I'll
squash it into the driver patch.

Catalin, Will, how do you want to handle the
arch/arm64/configs/defconfig change (patch 3)?  It's currently on my
branch, but I'm happy to drop it if another route is better.
