Subject: [RFC PATCH 0/6] Add SiFive FU740 PCIe host controller driver support

This patchset includes SiFive FU740 PCIe host controller driver. We also
add pcie_aux clock and pcie_power_on_reset controller to prci driver for
PCIe driver to use it.

This is tested with e1000e: Intel(R) PRO/1000 Network Card and SP M.2 PCIe
Gen 3 SSD in SiFive Unmatched.

Greentime Hu (5):
  clk: sifive: Add pcie_aux clock in prci driver for PCIe driver
  clk: sifive: Use reset-simple in prci driver for PCIe driver
  MAINTAINERS: Add maintainers for SiFive FU740 PCIe driver
  dt-bindings: PCI: Add SiFive FU740 PCIe host controller
  riscv: dts: Add PCIe support for the SiFive FU740-C000 SoC

Paul Walmsley (1):
  PCI: designware: Add SiFive FU740 PCIe host controller driver
