MDIO bitbang on Verdin IMX8M Mini


I need to connect a Verdin IMX8M Mini to an Ethernet switch. Since it is mentioned that the “Mini” model does not have RGMII exposed, which pins can I use for a bitbang MDIO/SMI?

Any regular GPIO-capable pin may be used with the generic GPIO bitbanging driver [1]. Please note, however, that we do NOT have this driver (CONFIG_MDIO_GPIO) enabled by default, so you will need to compile your own custom Linux kernel or Yocto Project image.
