Subject: [PATCH] net: phy: Add driver for Motorcomm yt8531 gigabit ethernet
|
|
phy
|
|
|
|
Add a driver for the motorcomm yt8531 gigabit ethernet phy. We have
|
|
verified the driver on AM335x platform with yt8531 board. On the
|
|
board, yt8531 gigabit ethernet phy works in utp mode, RGMII
|
|
interface, supports 1000M/100M/10M speeds, and wol(magic package).
