The Airoha AN8801R Gigabit Ethernet PHY is found on some boards such as the Mediatek Genio 720-EVK development kit. Louis-Alexis Eyraud and AngeloGioacchino Del Regno, both of Collabora, took to developing the "air_an8801" PHY driver for supporting this chip. This driver is based on a downstream kernel driver written by Airoha Technology that appears in Mediatek's vendor kernel derived from Linux 6.6.
Airoha promotes the AN8801R as a low-power, highly-integrated single-port Ethernet PHY transciever. This AN8801R PHY is geared for Ethernet switches, routers/gateways, set top boxes, smart TVs, game consoles, and more.
This new Gigabit Ethernet PHY driver was recently queued in net-next.git . With the driver being in the net-next code, it will be submitted for the upcoming Linux 7.2 merge window. Enabling the new driver is gated by the new AIR_AN8801_PHY Kconfig option.
