Hi,
just FYI, I wanted to test recent Mika's DMA/ep93xx_eth fixes, so I've added
this patch also and it oopsed. 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

Hi,
just FYI, I wanted to test recent Mika's DMA/ep93xx_eth fixes, so I've added
this patch also and it oopsed. 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
