Subject: [v6,0/4] PCI: mediatek: Add new generation controller support

These series patches add pcie-mediatek-gen3.c and dt-bindings file to
support new generation PCIe controller.

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
