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 to support Kirin 970. Patch 4 were imported from Manivannan's HiKey 970 96boards 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. The remaining patches contain several cleanups applied on the top of Manivann's work. They cleanup the code and change it to use the DT bindings defined on patch 3. --- v2: - DTS bindings dropped, as they depend on other DTS changes that will be happening at staging and ARM trees; - Use regulator_get() for Kirin 970, instead of regulator_get_optional(); - The power supply was renamed to "pcie_vdd", in order to better match the schematics; - The patch descriptions were renamed in order to match the terms used by other PCI patches; - dts patches removed from this series, as they depend on other patches being merged via other trees.
