If I revert this patch, it seems to work so far. You can find the whole patchset I've been testing on the GitHub[1]. I've tested it on ts-7250 and ts-7300, the oops is same. Here's the oops: ep93xx-eth version 0.1 loading ep93xx_eth_mii: probed ep93xx_eth:ep93xx_mii_probe: no PHY found ep93xx-eth ep93xx-eth: failed to probe MII bus ------------[ cut here ]------------
