This is a driver for AX88796C Ethernet Adapter connected in SPI mode as
found on ARTIK5 evaluation board. The driver has been ported from a
v3.10.9 vendor kernel for ARTIK5 board.

Changes in v6:
  - fixed typos in Kconfig
  - checked argument value in ax88796c_set_tunable
  - updated tags in commit messages

Changes in v5:
  - coding style (local variable declarations)
  - added spi0 node in the DT binding example and removed
    interrupt-parent
  - removed comp module parameter
  - added CONFIG_SPI_AX88796C_COMPRESSION option to set the initial
    state of SPI compression
  - introduced new ethtool tunable "spi-compression" to controll SPI
    transfer compression
  - removed unused fields in struct ax88796c_device
  - switched from using buffers allocated on stack for SPI transfers
    to DMA safe ones embedded in struct ax_spi and allocated with
    kmalloc()

Changes in v4:
  - fixed compilation problems in asix,ax88796c.yaml and in
  ax88796c_main.c introduced in v3

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

  dt-bindings: vendor-prefixes: Add asix prefix
  dt-bindings: net: Add bindings for AX88796C SPI Ethernet Adapter

Please don't send patches which were applied. It confuses everyone and
could cause double-applying through different tree.
