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.
