Adding APM X-Gene SoC Ethernet driver. v7: Address comments from v6 review * fixed skb memory leak when dma_map_single fails in xmit.
v6: Address comments from v5 review * added basic ethtool support * added ndo_get_stats64 call back * deleted priting Rx error messages * renamed set_bits to xgene_set_bits to fix kbuild error (make ARCH=powerpc) v5: Address comments from v4 review * Documentation: Added phy-handle, reg-names and changed mdio part * dtb: Added reg-names supplemental property * changed platform_get_resource to platform_get_resource_byname * added separate tx/rx set_desc/get_desc functions to do raw_write/raw_read * removed set_desc/get_desc table lookup logic * added error handling logic based on per packet descriptor bits * added software managed Rx packet and error counters * added busy wait for register read/writes * changed mdio_bus->id to avoid conflict * fixed mdio_bus leak in case of mdio_config error * changed phy reg hard coded value to MII_BMSR * changed phy addr hard coded value to phy_device->addr * added paranthesis around macro arguments * converted helper macros to inline functions * changed use of goto's only to common work such as cleanup v4: Address comments from v3 review * MAINTAINERS: changed status to supported * Kconfig: made default to no * changed to bool data type wherever applicable * cleaned up single bit set and masking code * removed statistics counters masking * removed unnecessary OOM message printing * fixed dma_map_single and dma_unmap_single size parameter * changed set bits macro body using new set_bits function v3: Address comments from v2 review * cleaned up set_desc and get_desc functions * added dtb mdio node and phy-handle subnode * renamed dtb phy-mode to phy-connection-type * added of_phy_connect call to connec to PHY * added empty line after last local variable declaration * removed type casting when not required * removed inline keyword from source files * removed CONFIG_CPU_BIG_ENDIAN ifdef v2 * Completely redesigned ethernet driver * Added support to work with big endian kernel * Renamed dtb phyid entry to phy_addr * Changed dtb local-mac-address entry to byte string format * Renamed dtb eth8clk entry to menetclk v1 * Initial version Signed-off-by: Iyappan Subramanian <isubraman...@apm.com> Signed-off-by: Ravi Patel <rapa...@apm.com> Signed-off-by: Keyur Chudgar <kchud...@apm.com> --- Iyappan Subramanian (4): MAINTAINERS: Add entry for APM X-Gene SoC ethernet driver Documentation: dts: Add bindings for APM X-Gene SoC ethernet driver dts: Add bindings for APM X-Gene SoC ethernet driver drivers: net: Add APM X-Gene SoC ethernet driver support. .../devicetree/bindings/net/apm-xgene-enet.txt | 72 ++ MAINTAINERS | 8 + arch/arm64/boot/dts/apm-mustang.dts | 4 + arch/arm64/boot/dts/apm-storm.dtsi | 30 +- drivers/net/ethernet/Kconfig | 1 + drivers/net/ethernet/Makefile | 1 + drivers/net/ethernet/apm/Kconfig | 1 + drivers/net/ethernet/apm/Makefile | 5 + drivers/net/ethernet/apm/xgene/Kconfig | 9 + drivers/net/ethernet/apm/xgene/Makefile | 6 + .../net/ethernet/apm/xgene/xgene_enet_ethtool.c | 125 +++ drivers/net/ethernet/apm/xgene/xgene_enet_hw.c | 848 +++++++++++++++++++ drivers/net/ethernet/apm/xgene/xgene_enet_hw.h | 394 +++++++++ drivers/net/ethernet/apm/xgene/xgene_enet_main.c | 939 +++++++++++++++++++++ drivers/net/ethernet/apm/xgene/xgene_enet_main.h | 109 +++ 15 files changed, 2549 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/apm-xgene-enet.txt create mode 100644 drivers/net/ethernet/apm/Kconfig create mode 100644 drivers/net/ethernet/apm/Makefile create mode 100644 drivers/net/ethernet/apm/xgene/Kconfig create mode 100644 drivers/net/ethernet/apm/xgene/Makefile create mode 100644 drivers/net/ethernet/apm/xgene/xgene_enet_ethtool.c create mode 100644 drivers/net/ethernet/apm/xgene/xgene_enet_hw.c create mode 100644 drivers/net/ethernet/apm/xgene/xgene_enet_hw.h create mode 100644 drivers/net/ethernet/apm/xgene/xgene_enet_main.c create mode 100644 drivers/net/ethernet/apm/xgene/xgene_enet_main.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
