Hi From: Marek Vasut Sent: mardi 1 décembre 2020 11:35 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 v

[PATCH] ARM: dts: stm32: Switch to MCO2 for PHY 50 MHz clock

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.
