This patch series adds support for the Cygnus PCIe PHY and support of the MDC/MDIO bus interface found in various iProc based of SoCs. The iProc MDC/MDIO bus interface can be used by the host processor to communicate with various internal Serdes/PHYs including Ethernet, PCIe, USB, etc.
This patch series is based on Linux v4.1-rc4 and is avaliable in: https://github.com/Broadcom/cygnus-linux/tree/cygnus-pcie-phy-v2 Changes from v1: - Move the MDC/MDIO bus driver from drivers/phy/* to drivers/bus/* - Make the PCIe PHY device node child node of the MDIO bus - Change the PCIe PHY driver to tristate so it can be compiled as a module - Other minor changes Ray Jui (5): dt_bindings: Add iProc MDC/MDIO interface binding phy: iproc-mdio: Initial iProc MDC/MDIO support phy: cygnus: pcie: Define DT binding phy: cygnus: pcie: Add Cygnus PCIe PHY support ARM: dts: enable PCIe PHY support for Cygnus .../devicetree/bindings/bus/brcm,iproc-mdio.txt | 21 ++ .../bindings/phy/brcm,cygnus-pcie-phy.txt | 34 ++ arch/arm/boot/dts/bcm-cygnus.dtsi | 20 ++ drivers/bus/Kconfig | 12 + drivers/bus/Makefile | 1 + drivers/bus/iproc-mdio-bus.c | 255 +++++++++++++++ drivers/phy/Kconfig | 15 + drivers/phy/Makefile | 1 + drivers/phy/phy-cygnus-pcie.c | 340 ++++++++++++++++++++ include/linux/iproc_mdio_bus.h | 22 ++ 10 files changed, 721 insertions(+) create mode 100644 Documentation/devicetree/bindings/bus/brcm,iproc-mdio.txt create mode 100644 Documentation/devicetree/bindings/phy/brcm,cygnus-pcie-phy.txt create mode 100644 drivers/bus/iproc-mdio-bus.c create mode 100644 drivers/phy/phy-cygnus-pcie.c create mode 100644 include/linux/iproc_mdio_bus.h -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
