[PATCH 00/13] Add support for Hikey 970 PCIe

[Mauro Carvalho Chehab]

This series add support for Kirin 970 and for the Hikey 970
board at the already-existing  driver.

patches 1-3 were previously submitted as RFC:

- Patch 1 converts the Synopsys Designware PCIe binding
  documentation to the DT schema;
- Patch 2 converts the pcie-kirin DT binding to the DT schema;
- Patch 3 adds some extra configuration needed by
  Kirin 970.

Patches 4-5 were imported from Manivannan's Hikey 970
tree:

   https://git.linaro.org/people/manivannan.sadhasivam/96b-common.git/commit/?h=hikey970_pcie&id=4917380ad023c62960aa0f876bd4f23cefc8729e

It contains the original port made by Linaro.

patches 6 to 12 contains several cleanups applied on the
top of Manivann's work, in order to simplify the extra data
that would be required at DT, and to ensure that the power
regulator needed to enable the PCI support on Hikey970
will be enabled before trying to power it on, as otherwise,
PCI resource allocation will fail.

-

patch 13 is here mostly as an example about what is needed
in order for PCIe (and Ethernet) to start working on Hikey 970.

It won't apply cleanly, as it depends on another patch series,
adding the needed regulator drivers.

I'll re-submit patch 13 after the pending stuff gets merged
upstream.
