[PATCH v2 0/2] Add PCIe host driver support for Mediatek SoCs

From: Ryder Lee
Date: Thu May 04 2017 - 05:33:54 EST


This patch series add Mediatek Gen2 PCIe host controller driver and
dt-binding document. It can be found on MT7623 series SoCs.

This driver was validated using Broadcom Tigon3 and Intel(R) 82575/82576
gigabit ethernet card.

Changes since v2:
- modify Kconfig to avoid kbuild test error on some architecture.
- change compatible string.
- revise binding document:
add missing interrupt-names.
remove the board dts example and drop 'status' properties.
remove unnecessary descriptions bout standard PCI bus binding.

Changes since v1:
- add .suppress_bind_attrs.
- remove unnecessary *_valid_device() pattern.
- remove PCI_PROBE_ONLY.
- use the regular readl() instead of readl_relaxed().
- add .map_bus() and change to use pci_generic_config_read/pci_generic_config_write.
- revise dt-binding document and move nonstandard properties to root node.
- change compatible string.
- use interrupt-map property and replace mtk_pcie_map_irq() with of_irq_parse_and_map_pci().
- use the new pci_register_host_bridge() method instead of pci_scan_root_bus().
