According to the documentation, it is a 3.70a but I learn (the hard way) not to trust the documentation too much. Is there anyway to make sure which version we have. Like a register to read ? Out of curiosity, I changed the compatible to "snps,dwmac-3.710" anyway. For some reason, the MDIO bus failed to register with this. Since it is not the documented version, I did not check why. > > > > > By the way, your mailer (and its auto 80 column rule I suppose) made the > > patch > > below a bit harder to apply > > Sorry.
