This patchset addresses the following issues, 1. Fixes the kernel crash when the driver loaded as an kernel module - by fixing hardware cleanups and rearrange kernel API calls 2. Hot-plug issue on the SGMII 1G interface - by adding a driver for MDIO management Signed-off-by: Iyappan Subramanian <isubramanian@xxxxxxx> Tested-by: Fushen Chen <fchen@xxxxxxx> Tested-by: Toan Le <toanle@xxxxxxx> --- v7: Address review comments from v6 - fixed kbuild warnings - unmapped DMA memory on xgene_enet_delete_bufpool() - delete descriptor rings and buffer pools on cle_init() failure - fixed error deconstruction path on probe v6: Address review comments from v5 - changed to use devm_ioremap_resource - changed to return PTR_ERR(clk) on failure - cleaned up and removed indirections - exported mdio read/write and phy_register functions - changed mii_bus is to indicate interface instance - changed to call the exported mdio read/write and phy_register functions v5: Address review comments from v4 - Fixed clock reset sequence by adding delay - Fixed clock count by adding clk_unprepare_disable() in port shutdown v4: Address review comments from v3 - Reorganized into smaller patches - Added wrapper functions for sgmii_control_reset and sgmii_tbi_control_reset - Removed clk_get warning info - mdio: Changed the order of 'if' statements and removed the 'else' statement - mdio: Removed the mdio_read(write) indirection wrapper functions - ethtool: Fixed SGMII 1G get_settings and set_settings - Documentation: dtb: Added MDIO node information - MAINTAINERS: Added MDIO driver and documentation path v3: Address review comments from v2 - Add comment about hardware clock reset sequence on xgene_mdio_reset v2: Address review comments from v1 - Fixed patch 1 compilation error - Fixed mdio@1f610000 xge0clk reference - Squashed dtb patches - Added PORT_OFFSET macro v1: - Initial version --- Iyappan Subramanian (12): drivers: net: xgene: Separate set_speed from mac_init drivers: net: xgene: Fix module unload crash - hw resource cleanup drivers: net: xgene: Fix module unload crash - change sw sequence drivers: net: xgene: Fix module unload crash - clkrst sequence drivers: net: phy: xgene: Add MDIO driver drivers: net: xgene: Add backward compatibility drivers: net: xgene: Enable MDIO driver drivers: net: xgene: Use exported functions drivers: net: xgene: ethtool: Use phy_ethtool_gset and sset dtb: xgene: Add MDIO node Documentation: dtb: xgene: Add MDIO node MAINTAINERS: xgene: Add driver and documentation path .../devicetree/bindings/net/apm-xgene-mdio.txt | 37 ++ MAINTAINERS | 2 + arch/arm64/boot/dts/apm/apm-merlin.dts | 6 + arch/arm64/boot/dts/apm/apm-mustang.dts | 12 + arch/arm64/boot/dts/apm/apm-shadowcat.dtsi | 11 +- arch/arm64/boot/dts/apm/apm-storm.dtsi | 26 +- drivers/net/ethernet/apm/xgene/Kconfig | 1 + .../net/ethernet/apm/xgene/xgene_enet_ethtool.c | 22 +- drivers/net/ethernet/apm/xgene/xgene_enet_hw.c | 255 ++++++----- drivers/net/ethernet/apm/xgene/xgene_enet_hw.h | 11 +- drivers/net/ethernet/apm/xgene/xgene_enet_main.c | 215 ++++++---- drivers/net/ethernet/apm/xgene/xgene_enet_main.h | 33 +- drivers/net/ethernet/apm/xgene/xgene_enet_sgmac.c | 239 +++++++++-- drivers/net/ethernet/apm/xgene/xgene_enet_sgmac.h | 8 + drivers/net/ethernet/apm/xgene/xgene_enet_xgmac.c | 66 ++- drivers/net/ethernet/apm/xgene/xgene_enet_xgmac.h | 3 + drivers/net/phy/Kconfig | 6 + drivers/net/phy/Makefile | 1 + drivers/net/phy/mdio-xgene.c | 477 +++++++++++++++++++++ drivers/net/phy/mdio-xgene.h | 143 ++++++ 20 files changed, 1291 insertions(+), 283 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/apm-xgene-mdio.txt create mode 100644 drivers/net/phy/mdio-xgene.c create mode 100644 drivers/net/phy/mdio-xgene.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
