Subject: [PATCH] net: phy: add Motorcomm YT8531S phy id.
|
|
|
|
We added patch for motorcomm.c to support YT8531S. This patch has
|
|
been tested on AM335x platform which has one YT8531S interface
|
|
card and passed all test cases.
|
|
The tested cases indluding: YT8531S UTP function with support of
|
|
10M/100M/1000M; YT8531S Fiber function with support of 100M/1000M;
|
|
and YT8531S Combo function that supports auto detection of media type.
|
|
|
|
Since most functions of YT8531S are similar to YT8521 and we reuse some
|
|
codes for YT8521 in the patch file.
