Unlike most other conversions, this one is not by far a trivial one, and should be seen as "Layerscape PCS meets PHYLINK". Actually, the PCS doesn't need a lot of hand-holding and most of our other devices 'just work' (this one included) without any sort of operating system awareness, just an initialization procedure done typically in the bootloader. Our issues start when the PCS stops from "just working", and that is where PHYLINK comes in handy. The PCS is not specific to the Vitesse / Microsemi / Microchip switching core at all. Variations of this SerDes/PCS design can also be found on DPAA1 and DPAA2 hardware. The main idea of the abstraction provided is that the PCS looks so much like a PHY device, that we model it as an actual PHY device and run the generic PHY functions on it, where appropriate.... Series applied, please address any follow-up feedback you receive. Thank you.
Thanks David, sure, ready for action. -Vladimir
