Well that was my next part to tackle indeed...

TBH I haven't considered that, I guess this would definitely make thing much easier. Since the register layout of the TSE PCS is very very similar to the C22 layout, that could be indeed justified, as it's basically a set of standard mdio registers exposed through mmio.
Thanks for the tip.
However this current patch still makes sense though right ?
