It’s the MAC trying to signal “power-up the PHY”. So we modelled it like a “wake-up output” from the MAC... >> For easier migration for the Designware driver, the prefix of DTB >> entries has simply been changed from 'snps,' to 'allwinner,': >> i.e. 'snps,reset-gpio' became 'allwinner,reset-gpio'. > > The upstrmea driver will use the snps prefix. In fact I have a patch floating around here, which merges the sun8i_emac back into designware.c (there really isn’t any difference) and then uses the snps,reset-gpio. Given that I found it a bit less appropriate to have that patch out first, this is the consensus change to fall back onto in case the bigger change gets shot down.
