     Shouldn't SH7763 come after SH7757?

    I think you can merge it to patch #1 with a corresponding comment in 
the changelog. This is hardly worth separate patch.

     I think you need to annotate this function with __maybe_unused as 
well since some SoC don't use it.

     Alternatively, you could use two 'struct net_device_ops' instances, 
one with TSU-specific methods installed and one without. That would work 
with any combination of Ether devices having and not having TSU (though 
such combinations don't seem to exist in practice).

    Only "configuration" (and the same typo in the subject).
