Commit Message

Sriranjani P Jan. 11, 2023, 7:54 a.m. UTC
  The FSD SoC contains two instances of Synopsys DWC QoS Ethernet IP, one in
FSYS0 block and other in PERIC block.

Adds device tree node for Ethernet in PERIC Block and enables the same for
FSD platform.

Sorry somehow I'm not able to find my previous mail chain.
I had replied to your comment in the previous version of the mail.
In this case alias id is used to differentiate between Ethernet instance 0 and 1 in the driver code.

If you mean to say that the nodes are supposed to be in the increasing order of physical address,
I can see that the existing file is not arranged in that format. If that is required I can first fix the
existing file and post the revised patch for the same.
