              description:

                When ksz88x3 is acting as clock provier (via REFCLKO) it

                can select between internal and external RMII reference

                clock. Internal reference clock means that the clock for

                the RMII of ksz88x3 is provided by the ksz88x3 internally

                and the REFCLKI pin is unconnected. For the external

                reference clock, the clock needs to be fed back to ksz88x3

                via REFCLKI.

                If microchip,rmii-clk-internal is set, ksz88x3 will provide

                rmii reference clock internally, otherwise reference clock

                should be provided externally.
