From: Honghui Zhang <honghui.zhang@xxxxxxxxxxxx> MediaTek's PCIe host controller has two generation HWs, the new generation HW has two root ports, it shares most probing flow with the legacy controller. But the read/write config space logical is different from the lagacy controller. This patchset abstract the common probing flow, and add support for the new generation controller. Changes since v1: - Fix build warnings in arm arch. - Using SoC specific compatible instead of generic compatible. - Add devicetree binding example for mt7622. - Unified the register define names with PCIE_ prefix. - Cleanup some un-necessary condition determine when starup port. - minor code cleanups.
