From: Chunyan Zhang <chunyan.zhang@xxxxxxxxxx> This series adds PCIe controller driver for Unisoc SoCs. This controller is based on DesignWare PCIe IP. This RESEND patch set V6 is based on v5.12-rc4. Changes since v5: * Change "GPL v2" to "GPL". * Remove exit_p wrapper which used to define remove callback. Changes since v4: * Install 'yamllint' and upgrade dt-schema in order to solve the yamllint and dtschema/dtc warnings/errors: Changes since v3: * Split the property 'sprd,pcie-poweron-syscons' and 'sprd,pcie-poweroff-syscons' into reset, power domains, phy and so on; * Delete the function to get resource 'msi' and 'dbi' which were parsed by the DW core; * Delete the function 'sprd_pcie_host_init', because the DW core has done it. Changes since v2: * Change RC mode to host mode in drivers/pci/controller/dwc/Kconfig; * Change Signed-off-by from Billows Wu to Hongtao Wu Changes since v1: * 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/ * Delete empty function; * Document property "sprd,pcie-poweron-syscons" and 'sprd,pcie-poweroff-syscons'; * Delete runtime suspend/resume function; * Add COMPILE_TEST which CONFIG_PCIE_SPRD depends on.
