Stmmac: regression on probing driver


#1

I noticed that after adding hwif.c in 4.17 the initialization of driver is not correct due to incrorrect synopsys_id, because register reading returns 0. The first assert/deassert is done of dwmac-socfpga.c while selelcting phy mode, another assert/deassert is done stmmac_main.c. Does anyone know proper fix for that?

The output of dmesg:
