Description Stefan Grundmann 2021-12-31 16:24:16 UTC 
my comment in review R10:f77d8d10115b0863cc3dfd6e1746c02847d6569d

This commit changed the behavior of dwc_attach() in a way that broke ethernet on my Allwinner A20 based cubieboard2:
 
root@cubieboard2:~ # ofwdump -P 'phy-mode' /soc/ethernet@1c50000
Node 0x5354: ethernet@1c50000
  phy-mode:
    6d 69 69 00
    'mii'
 
 
before this commit; dwc_attach() on the cubieboard2 would leave set sc->phy_mode alone (which is fine since sys/arm/allwinner/aw_if_dwc.
c does not need this information).
now it fails with ENXIO.
