> The LAN8710i PHY currently uses 50 MHz clock direct from PLL4P.
> To permit PLL4P to run at faster frequency, use MCO2 as a divider.
> The PLL4P runs at 100 MHz, supplies MCO2 which divides it by 2 to 50MHz, and supplies the PHY with 50 MHz via pin PG2. The feedback clock are fed back in via pin PA1.

Applied to u-boot-stm/master, thanks!
