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. Signed-off-by: Adam Ford <redacted>Thanks for your patch!quoted

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!
