Some improvements:
- manage syscfg as optional clock,
- update slew rate of ETH_MDIO pin,
- Enable gating of the MAC TX clock during TX low-power mode
V4: Update with Andrew Lunn remark

net: ethernet: stmmac: Add support for syscfg clock
ARM: dts: stm32: remove syscfg clock on stm32mp157c ethernet

I'll take DT patches in my STM32 tree.
Thanks

Ok, I took patch #1 into net-next.

For DT patches:
Applied on stm32-next.
Thanks.
