Fugang Duan says:
====================
net: fec: driver code clean and bug fix
The patch serial include code clean and bug fix:
Patch#1: avoid dummy operation during suspend/resume test.
Patch#2: bug fix for i.MX6SX SOC that clean all interrupt events during MAC initial process.
Patch#3: before phy device link status is up, only enable MDIO bus interrupt.
V2:
- Modify the comment form from David's suggestion.
