This series adds PCIe support for the Qualcomm Hawi SoC. The Hawi
platform features two PCIe controllers: one capable of Gen3 x2 operation
and one capable of Gen4 x1 operation. The first patch adds the device
tree bindings documentation for the Hawi PCIe controller, and the second
patch adds driver support by enabling the Hawi compatible string in the
existing qcom PCIe driver.
