Signed-off-by: Randolph Lin --- Changes in v10: - Use "qilai" instead of "andes" as the tag Changes in v9: - Drop the patch that adjusts the number of OB/IB windows. - Made minor adjustments based on the reviewer's suggestions. Changes in v8: - Fix the compile error reported by the kernel test robot. Changes in v7: - Remove unnecessary nodes and property in DTS bindings Changes in v6: - Fix typo in the logic for adjusting the number of OB/IB windows Changes in v5: - Add support to adjust the number of OB/IB windows in the glue driver. - Fix the number of OB windows in the Qilai PCIe driver. - Remove meaningless properties from the device tree. - Made minor adjustments based on the reviewer's suggestions. Changes in v4: - Add .post_init callback for enabling IOCP cache. - Sort by vender name in Kconfig - Using PROBE_PREFER_ASYNCHRONOUS as default probe type. - Made minor adjustments based on the reviewer's suggestions. Changes in v3: - Remove outbound ATU address range validation callback and logic. - Add logic to skip failed outbound iATU configuration and continue. - Using PROBE_PREFER_ASYNCHRONOUS as default probe type. - Made minor adjustments based on the reviewer's suggestions. Changes in v2: - Remove the patch that adds the dma-ranges property to the SoC node. - Add dma-ranges to the PCIe parent node bus node. - Refactor and rename outbound ATU address range validation callback and logic. - Use parent_bus_offset instead of cpu_addr_fixup(). - Using PROBE_DEFAULT_STRATEGY as default probe type. - Made minor adjustments based on the reviewer's suggestions.
