[PATCH v10 0/4] Add PCI support to AXS10x

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



>From Joao's v9 posting
(http://lkml.kernel.org/r/cover.1454952698.git.jpinto at 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."

Here's what I'm looking for before putting this in "next":

  - An ack from the DesignWare maintainers (Jingoo or Pratyush)
  - An ack from Arnd for the DT updates/driver name/etc
  - A response from Murali about the Keystone establish_link strategy
    (I posted this question to Joao's v9 posting)
  - An update for pcie-qcom.d to use dw_pcie_wait_for_link() or a reason
    why it can't use it

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-synopsys

Joao, if you post a v11, please grab my pci/host-synopsys, make your edits,
then post the entire new v11 series as complete patches based on v4.5-rc1.
