The previous try of setting the PHY latency was here[1]. But this approach could not work for multiple reasons: - the interface was not generic enough so it would be hard to be extended in the future - if there were multiple time stamper in the system then it was not clear to which one should adjust these values.
So the next try is to extend sysfs and configure exactly the desired PHY. Therefore add a new entry in sysfs for the PHY('adjust_latency') which will be shown only if the PHY implements the set/get_adj_latency.
