Synopsys GMAC 4.10 is used. And Phy mode for eval and disco is RMII with PHY SMSC LAN8742 Signed-off-by: Christophe Roullier <redacted> --- arch/arm/boot/dts/stm32h743-pinctrl.dtsi | 15 +++++++++++++++ arch/arm/boot/dts/stm32h743.dtsi | 13 +++++++++++++ arch/arm/boot/dts/stm32h743i-disco.dts | 17 +++++++++++++++++ arch/arm/boot/dts/stm32h743i-eval.dts | 17 +++++++++++++++++ 4 files changed, 62 insertions(+)
