+ 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.
