From: Hongtao Wu <billows.wu@xxxxxxxxxx> This series adds PCIe controller driver for Unisoc SoCs. This controller is based on DesignWare PCIe IP. Changes from v1: 1) Test this patch on top of Rob Herring's 40 part series of DWC clean-ups: https://lore.kernel.org/linux-pci/20200821035420.380495-1-robh@xxxxxxxxxx/ 2) Delete empty function 3) Document property "sprd,pcie-poweron-syscons" and 'sprd,pcie-poweroff-syscons' 4) Delete runtime suspend/resume function 5) Add COMPILE_TEST which CONFIG_PCIE_SPRD depends on Changes from v2: 1) Change RC mode to host mode in drivers/pci/controller/dwc/Kconfig 2) Change Signed-off-by from Billows Wu to Hongtao Wu Changes from v3: 1) Split the property 'sprd,pcie-poweron-syscons' and 'sprd,pcie-poweroff-syscons' into reset, power domains, phy and so on. 2) Delete the function to get resource 'msi' and 'dbi' which were parsed by the DW core. 3) Delete the function 'sprd_pcie_host_init', because the DW core has done it. Changes from v4: 1) Install 'yamllint' and upgrade dt-schema in order to solve the yamllint and dtschema/dtc warnings/errors.
