Subject: [PATCH net-next 0/6] net: stmmac: add and use library for setting
 clock

Hi,

There is a common theme throughout several "bsps" in the stmmac driver
which all code up the same thing: for 10M, 100M and 1G, select the
appropriate 2.5MHz, 25MHz, or 125MHz clock.

Rather than having every BSP implement the same thing but slightly
differently, let's provide a single implementation which is passed
the struct clk and the speed, and have that do the speed to clock
rate decode.

Note: only build tested.
