Subject: [PATCH] net: phy: Initialize mdio clock at probe function
|
||
|
|
|
||
|
|
USB PHYs need the MDIO clock divisor enabled earlier to work.
|
||
|
|
Initialize mdio clock divisor in probe function. The ext bus
|
||
|
|
bit available in the same register will be used by mdio mux
|
||
|
|
to enable external mdio.
