Changes in v6: 1. Export pci_pio_to_address() to support compiling as kernel module; 2. Replace usleep_range(100 * 1000, 120 * 1000) with msleep(100); 3. Replace dev_notice with dev_err; 4. Fix MSI get hwirq flow; 5. Fix warning for possible recursive locking in mtk_pcie_set_affinity. Changes in v5: 1. Remove unused macros 2. Modify the config read/write callbacks, set the config byte field in TLP header and use pci_generic_config_read32/write32 to access the config space 3. Fix the settings of translation window, both MEM and IO regions works properly 4. Fix typos Changes in v4: 1. Fix PCIe power up/down flow 2. Use "mac" and "phy" for reset names 3. Add clock names 4. Fix the variables type Changes in v3: 1. Remove standard property in binding document 2. Return error number when get_optional* API throws an error 3. Use the bulk clk APIs Changes in v2: 1. Fix the typo of dt-bindings patch 2. Remove the unnecessary properties in binding document 3. dispos the irq mappings of msi top domain when irq teardown Jianjun Wang (4): dt-bindings: PCI: mediatek: Add YAML schema PCI: Export pci_pio_to_address() for module use PCI: mediatek-gen3: Add MediaTek Gen3 driver for MT8192 MAINTAINERS: Add Jianjun Wang as MediaTek PCI co-maintainer .../bindings/pci/mediatek-pcie-gen3.yaml | 135 ++ MAINTAINERS | 1 + drivers/pci/controller/Kconfig | 13 + drivers/pci/controller/Makefile | 1 + drivers/pci/controller/pcie-mediatek-gen3.c | 1084 +++++++++++++++++ drivers/pci/pci.c | 1 + 6 files changed, 1235 insertions(+) create mode 100644 Documentation/devicetree/bindings/pci/mediatek-pcie-gen3.yaml create mode 100644 drivers/pci/controller/pcie-mediatek-gen3.c
