+From 813abcd98fb1b2cccf850cdfa092a4bfc50b2363 Mon Sep 17 00:00:00 2001
+From: Frank <Frank.Sae@motor-comm.com>
+Date: Tue, 22 Nov 2022 16:42:32 +0800
+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.
