Hi Vinod, The patch series started out as you mentioned. We used to have phy tune register values passed from dT to driver and written to respective registers in the driver code. But it was later suggested not to pass register values from dT. Instead define the meaningful properties that make up the phy tuning parameters and pass their values from dT. The driver code is supposed to convert these values and map them to required register values. This is why we had to come up with these parameters and declare them in bindings and dT.
