+Subject: [PATCH] net: phy: Add dts support for Motorcomm yt8531s gigabit
+ ethernet phy
+
+Add dts support for Motorcomm yt8531s gigabit ethernet phy.
+ Change yt8521_probe to support clk config of yt8531s. Becase
+ yt8521_probe does the things which yt8531s is needed, so
+ removed yt8531s function.
+ This patch has been verified on AM335x platform with yt8531s board.
