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 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
