Subject: [PATCH v2 0/5] PCI: MediaTek: Add support for new generation host controller

From: Honghui Zhang <honghui.zhang@...iatek.com>

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.

Ryder Lee (5):
  PCI: mediatek: Add a structure to abstract the controller generations
  PCI: mediatek: switch to use platform_get_resource_byname()
  dt-bindings: PCI: rename and cleanup MediaTek binding text
  PCI: mediatek: Add new generation controller support
  dt-bindings: PCI: add support for new generation controller
