For devices that use a programmable clock for the AVB reference clock,
the driver may need to enable them.  Add code to find the optional clock
and enable it when available.

Thanks for your patch!

Shouldn't the reference clock be disabled in case of any failure below?
I'll generate a V4.

Should I just regenerate this patch since it seems like the rest are
OK, or should I regenerate the whole series?
As the DT bindings haven't been applied yet, I think it would be
best if you would send a v4 with just the patches for the netdev
tree (i.e. DT bindings patch 1 and driver patch 4).

I will take the DT patches from this series, once the bindings have been
accepted.

Thank you!
