[PATCH v5 0/10] Add endpoint driver for Rockchip PCIe controller

[Shawn Lin]

Hi Lorenzo,

    This's the 5th try to upstream endpoint driver for Rockchip PCIe
controller. In previous discussion, we both agree to do some directory
reconstruction as soon as possible in 4.17 cycle. So the first 3 patches
attempt to move forward with that.

Then patch 4-9 are mostly the same as previous version, but just
fold in the fixes found by Kbuild Robot.

And patch 10 will update the defconfig for arm64 to avoid the warning,
which may go via linux-rockchip tree.

Hope it looks good to you. :)

Changes in v5:
- fix all issues found by Kbuild Robot
- rename directory from host to controller, and move back dwc and cadence

Changes in v4:
- remove empty line
- keep rockchip's order next to cadence and dwc, but we will
  try to resort it later when reconstructing the directories

Changes in v2:
- remove rockchip,rk3399-pcie-host compatible(Suggested by Rob)
- fix some error handling
