stm32mp157dk2 Ethernet irq poll

[AVazquez]

Hi!

I have been reviewing the kernel log for the DK2 Kit, and I have noticed that the Ethernet configuration is in polling mode.

[   37.074899] stm32-dwmac 5800a000.ethernet eth0: PHY [stmmac-0:00] driver [RTL8211F Gigabit Ethernet] (irq=POLL)

Is there a specific reason for the decision to have it in polling mode?

Upon examining the schematic, I can see that the interrupt signal is on PA6(ETH_MDINT).

I understand that the configuration for the interruption should be:

interrupt-parent = <&gpioa>;
interrupts = <6 IRQ_TYPE_EDGE_FALLING>;

Hi @AVazquez ,

I assume this is very similar of this post: https://community.st.com/t5/stm32-mpus-products/alternate-function-eth1-phy-intn-from-stm32mp15c/m-p/595868
