Adding APM X-Gene SoC Ethernet driver. v10: Address comments from v9 review * Documentation: aligned descriptions * simplified struct platform_driver initialization * fixed xgene_enet_mdio_config error path * fixed xgene_enet_init_hw error path * removed statistics spin_lock as it is not required * changed raw_desc fields to type __le64 * defined helper macros for set/get raw_descriptor fields v9: Address comments from v8 review * changed to direct read/write, byteswap into raw descriptor * fixed xgene_enet_create_desc_ring() error handling * removed references to IS_ERR_OR_NULL * disabled half duplex on phy_devce supported/advertising * simplified xgene_enet_adjust_link() function * fixed sparse tool compilation warnings v8: Address comments from v7 review * changed angle bracket to double quotes in header file include. 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 <isubramanian@xxxxxxx> Signed-off-by: Ravi Patel <rapatel@xxxxxxx> Signed-off-by: Keyur Chudgar <kchudgar@xxxxxxx> --- Iyappan
