This patch series adds support for the ASPEED PCIe Root Complex,
including device tree bindings, pinctrl support, and the PCIe host controller
driver. The patches introduce the necessary device tree nodes, pinmux groups,
and driver implementation to enable PCIe functionality on ASPEED platforms.
Summary of changes:
- Add device tree binding documents for ASPEED PCIe PHY, PCIe Config, and PCIe RC
- Update MAINTAINERS for new bindings and driver
- Add PCIe RC node and PERST control pin to aspeed-g6 device tree
- Add PCIe RC PERST pin group to aspeed-g6 pinctrl
- Implement ASPEED PCIe Root Complex host controller driver
This series has been tested on AST2600/AST2700 platforms and enables PCIe device
enumeration and operation.
Feedback and review are welcome.
