- 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.
