The driver has been ported from a v3.10.9 vendor kernel for ARTIK5 board. Changes in v3: - modify vendor-prefixes.yaml in a separate patch - fix several problems in the dt binding - removed unnecessary descriptions and properties - changed the order of entries - fixed problems with missing defines in the example - change (1 << N) to BIT(N), left a few (0 << N) - replace ax88796c_get_link(), ax88796c_get_link_ksettings(), ax88796c_set_link_ksettings(), ax88796c_nway_reset(), ax88796c_set_mac_address() with appropriate kernel functions. - disable PHY auto-polling in MAC and use PHYLIB to track the state of PHY and configure MAC - propagate return values instead of returning constants in several places - add WARN_ON() for unlocked mutex - remove local work queue and use the system_wq - replace phy_connect_direct() with phy_connect() and move devm_register_netdev() to the end of ax88796c_probe() (Unlike phy_connect_direct() phy_connect() does not crash if the network device isn't registered yet.) - remove error messages on ENOMEM - move free_irq() to the end of ax88796c_close() to avoid race condition - implement flow-control Changes in v2: - use phylib - added DT bindings - moved #includes to *.c files - used mutex instead of a semaphore for locking - renamed some constants - added error propagation for several functions - used ethtool for dumping registers - added control over checksum offloading - remove vendor specific PM - removed macaddr module parameter and added support for reading a MAC address from platform data (e.g. DT) - removed dependency on SPI from NET_VENDOR_ASIX - added an entry in the MAINTAINERS file - simplified logging with appropriate netif_* and netdev_* helpers - lots of style fixes Łukasz Stelmach (5): dt-bindings: vendor-prefixes: Add asix prefix dt-bindings: net: Add bindings for AX88796C SPI Ethernet Adapter net: ax88796c: ASIX AX88796C SPI Ethernet Adapter Driver ARM: dts: exynos: Add Ethernet to Artik 5 board ARM: defconfig: Enable ax88796c driver .../bindings/net/asix,ax88796c.yaml | 69 + .../devicetree/bindings/vendor-prefixes.yaml | 2 + MAINTAINERS | 6 + arch/arm/boot/dts/exynos3250-artik5-eval.dts | 29 + arch/arm/configs/exynos_defconfig | 2 + arch/arm/configs/multi_v7_defconfig | 2 + drivers/net/ethernet/Kconfig | 1 + drivers/net/ethernet/Makefile | 1 + drivers/net/ethernet/asix/Kconfig | 22 + drivers/net/ethernet/asix/Makefile | 6 + drivers/net/ethernet/asix/ax88796c_ioctl.c | 197 +++ drivers/net/ethernet/asix/ax88796c_ioctl.h | 27 + drivers/net/ethernet/asix/ax88796c_main.c | 1144 +++++++++++++++++ drivers/net/ethernet/asix/ax88796c_main.h | 578 +++++++++ drivers/net/ethernet/asix/ax88796c_spi.c | 111 ++ drivers/net/ethernet/asix/ax88796c_spi.h | 69 + 16 files changed, 2266 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/asix,ax88796c.yaml create mode 100644 drivers/net/ethernet/asix/Kconfig create mode 100644 drivers/net/ethernet/asix/Makefile create mode 100644 drivers/net/ethernet/asix/ax88796c_ioctl.c create mode 100644 drivers/net/ethernet/asix/ax88796c_ioctl.h create mode 100644 drivers/net/ethernet/asix/ax88796c_main.c create mode 100644 drivers/net/ethernet/asix/ax88796c_main.h create mode 100644 drivers/net/ethernet/asix/ax88796c_spi.c create mode 100644 drivers/net/ethernet/asix/ax88796c_spi.h -- 2.26.2
