Shame on me, it is a stupid copy/paste issue. For clocks, final
description could be:

 clocks: Must contain an entry for each entry in clock-names.
 clock-names: Should be "stmmaceth" for the host clock.
                       Should be "tx-clk" for the MAC TX clock.
                       Should be "rx-clk" for the MAC RX clock.

Does it seem good for you ?

Regards.

Alex
