>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. --- Joao Pinto (4): ARC: Add PCI support PCI: designware: Add generic dw_pcie_wait_for_link() PCI: designware: Add default link up check if sub-driver doesn't override PCI: designware: Add driver for prototyping kits based on ARC SDP .../devicetree/bindings/pci/designware-pcie.txt | 17 ++ MAINTAINERS | 7 + arch/arc/Kconfig | 26 ++++ arch/arc/include/asm/dma.h | 5 + arch/arc/include/asm/io.h | 9 + arch/arc/include/asm/pci.h | 31 ++++ arch/arc/kernel/Makefile | 1 arch/arc/kernel/pcibios.c | 22 +++ arch/arc/plat-axs10x/Kconfig | 1 drivers/pci/Makefile | 1 drivers/pci/host/Kconfig | 11 ++ drivers/pci/host/Makefile | 1 drivers/pci/host/pci-dra7xx.c | 11 -- drivers/pci/host/pci-exynos.c | 11 -- drivers/pci/host/pci-imx6.c | 11 -- drivers/pci/host/pcie-designware-plat.c | 138 ++++++++++++++++++++ drivers/pci/host/pcie-designware.c | 29 ++++ drivers/pci/host/pcie-designware.h | 6 + drivers/pci/host/pcie-spear13xx.c | 12 -- 19 files changed, 314 insertions(+), 36 deletions(-) create mode 100644 arch/arc/include/asm/pci.h create mode 100644 arch/arc/kernel/pcibios.c create mode 100644 drivers/pci/host/pcie-designware-plat.c
