>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." 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.
