> The Allwinner A523 SoC family provides two clock fanout pins, which are
> backed by gated clocks fixed to 25 MHz, divided down from the main
> peripheral PLL. Those are meant to clock an Ethernet PHY, and allow to
> save an external crystal oscillator typically employed for that purpose.
> 
> Add the pin descriptions of the two pins for those clocks, one is within
> the RGMII0 pins, the other within the RGMII1 pins, although the clock
> fanout works completely independently from the two MACs.
