We tested the patch locally with the mentioned defconfigs (am335x_evm_spiboot,
am335x_hs_evm, am335x_hs_evm_spi, am335x_hs_evm_uart), and we get the following
warning:

‘rmii1_mdio_pin_mux’ defined but not used [-Wunused-variable]

Are you referring to this warning or do you see any other build errors?

Thanks and Regards,
