[PATCH v2 0/3] Add missing ethernet reset ID for Amlogic SoC

[PATCH v2 0/3] Add missing ethernet reset ID for Amlogic SoC

[Anand Moon]

Add reset id for Ethernet to reset Ethernet IP.

Re-based on linux-next-20200730.
Could not test as their is build failed on linux-next-20200730. 

My observation:
- Sometime the device on upgrade of the kernel
  don't show up in the network.
- My observation that Ethernet interface come up successfully
  but no packet get forwarded.
- This happens some times on my network.

-Anand
