> With DM clock support in place, it is easy to add RMII support into the
> MAC driver. The RMII cannot operate at 1000 Mbps and at 100 and 10 Mbps
> the clock frequency is 50 MHz and 5 MHz instead of 25 MHz and 2.5 MHz.
> The board DT requires the following adjustments to EQoS node:
> phy-mode = "rmii";
> assigned-clock-parents = <&clk IMX8MP_SYS_PLL1_266M>,
> <&clk IMX8MP_SYS_PLL2_100M>,
> <&clk IMX8MP_SYS_PLL2_50M>;
> assigned-clock-rates = <0>, <100000000>, <50000000>;
