[PATCH v4 0/9] Add ethernet support for genio 520/720 EVK boards

[Julien Stephan]

This series adds ethernet support for genio 520/720 boards.

Particularly, it adds the following components:
- PHY driver for Airoha AN8801 (air_an8801.c).
- Synopsys DWC Ethernet QOS device support for MediaTek SoCs

This has been tested with a genio-520 evk board with the following
commands:

=> dhcp
DHCP client bound to address 192.168.1.44 (2246 ms)
=> ping 8.8.8.8
Using ethernet at 1101a000 device
host 8.8.8.8 is alive

The series also add a new entry in MAINTAINERS file for
drivers/net/phy/airoha/ drivers.

I also took the opportunity to do some cleanup on MAINTAINERS
drivers/net/Makefile and drivers/net/Kconfig files
