Hi Bjorn!

Is it possible to pull this patch set into 4.5?

Thanks

Subject: [PATCH v11 0/4] ARC: Add PCI support

>From Joao's v9 posting
(http://lkml.kernel.org/r/cover.1454952698.git.jpinto@synopsys.com):

  "This patch set has the goal to add suppport for DesignWare PCIe RC in ARC
  AXS10x. It includes the necessary tweaks to:

   - the ARC architecture (PCI support)
   - the PCI subsystem (ARC CPU support)
   - to pcie-designware (Centralisation of wait for link routine)
   - to dra7xx, exynos, imx6 and spear13xx drivers to use the centralised
     code for link wait

  A simple module was (pcie-designware-plat) was created to contain the
  specific platform init code."

Changes from v10:
  - Update keystone link establishment to wait longer for link to come up
    before re-initiating link training
  - Also use generic dw_pcie_wait_for_link() in keystone and qcom drivers

I would still like acks from DesignWare maintainers (Jingoo or Pratyush), from Murali for the Keystone changes, and from Arnd for the DT updates.

This series is in my pci/host-synopsys branch here:
https://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/log/?h=pci/host-syn
