About phy_id_mask in PHY driver

[fyspkid]

Hi Community,

I am creating a new ethernet phy driver on I.MX6.

As a lot of phy drivers in I.MX6 kernel, I found there is a "phy_id_mask" in every phy driver.

I've already known about the "phy_id", but how do I get / calculate the "phy_id_mask"? 

Could anyone please help me?

(I am using NXP tja1100 phy in I.MX6qp sabresd)

Thank you very much!!
