Linux tends to ignore Marketing, because Marketing tends to change its
mind every 6 months. Also, Linux ignores companies being bought and
sold, changing their name. So this PHY will forever be called whatever
name you give it here. The vitesse PHY driver is an example of
this. They got bought by Microsemi, and then Microchip bought
Microsemi. The PHY driver is still called vitesse.c.

How about using the legal name, 'ON Semiconductor
Corporation'
