Conflict between ethernet and PMIC
I used this post https://community.st.com/t5/stm32-mpus-products/stm32mp151aac-custom-board-kernel-not-starting/td-p/587192 to figure out how to add interrupts to pmic and got my board to finally boot into Linux. I then added my ethernet to the dts and now there is a conflict on PA0. The ethernet uses that pin but the interrupt is set as <&exti 55 IRQ_TYPE_EDGE_FALLING> just like most of the eval boards. I saw some use A0 gpio for the interrupt. How do I fix this?
