This series adds support for the Frame DMA present on the VSC7514
switch. The FDMA is able to extract and inject packets on the
various ethernet interfaces present on the switch.

While adding FDMA support, bindings were switched from .txt to .yaml
and mac address read from device-tree was added to allow be set
instead of using random mac address.

Oh yes, finally some care and attention for the ocelot switchdev
driver. I'll review this soon, but I can't today.
Will you be keeping the hardware for some extended period of time, and
do you have some other changes planned as well?

Yes I'll keep the hardware for some time but I do not have other
changes planned yet. Maybe there will be additional changes later but
nothing sure.
