Subject: [PATCH v7 0/5] Loongson PCI Generic Driver 

Hi,

This series converts Loongson PCI into a generic PCI controller
driver and adds support for LS2K SoC and LS7A PCH's PCI support.

Is it possible to let patch 1~3 go through PCI tree and patch
4~5 go through MIPS tree?

Thanks.

v6: Drop first the patch of previous versions. Driver code clean-ups
according to rob's suggestion.

It looks like I had a wrong impression on generic IO port handeling
and now the issue has been fixed, I implemented PCI_IOBASE for MIPS[1].
Now the address is uniform here.

v7: Fix some minor issues.

Jiaxun Yang (5):
  PCI: Don't disable decoding when mmio_always_on is set
  PCI: Add Loongson PCI Controller support
  dt-bindings: Document Loongson PCI Host Controller
  MIPS: DTS: Loongson64: Add PCI Controller Node
  MIPS: Loongson64: Switch to generic PCI driver
