+* NI XGE Ethernet controller

+Required properties:
+- compatible: Should be "ni,xge-enet-2.00"
+- reg: Address and length of the register set for the device
+- interrupts: Should contain tx and rx interrupt
+- interrupt-names: Should be "rx" and "tx"

PATCH v4 2/2 net: ethernet: nixge: Add support for National Instruments XGE netdev

Add support for the National Instruments XGE 1/10G network device.

It uses the EEPROM on the board via NVMEM.

Signed-off-by Moritz Fischer <[email protected]>

Changes from v3:
- Added NIXGE prefix to MDIO constants
- Removed NIXGE_MAX_PHY_ADDR (unused)
- Consistency for NIXGE_MDIO_CXX_READ constants
- Use devm_mdiobus_alloc()
- Fixed order of netdev_unregister() and mdio_bus_unregister()
- Addressed feedback w.r.t. disconnecting the PHY
- Removed now superfluous max_frm_size member
- Fix SPDX vs module license to be 'GPL v2'
SPDX-License-Identifier: GPL-2.0

Changes from v2:
- Implement recv side NAPI
- Improved error handling
- Implemented C45 writes
- Added ethtool callbacks & blink functionality
- Improved nixge_ctrl_poll_timeout() macro
- Removed dev_dbg() for mdio accesses
- Added businfo to ethtool drvinfo

Changes from v1:
- Added dependency on ARCH_ZYNQ (Kbuild)
- Removed unused variables
- Use of_phy_connect as suggested
- Removed masking of (un)supported modes
- Added #define for some constants
- Removed empty pm functions
- Reworked mac_address handling
- Made nixge_mdio_*() static (sparse)
- Removed driver version
- Addressed timeout loop
- Adressed return values on timeout
