Arf, it's a shame I have missed this reports. It could have spared some
time by asking at you earlier.

About the issue itself. I understand that a clock is needed by the
orion-ehci driver. But even if the clock is not provided by the DT, it
should have been fixed by kirkwood_legacy_clk_init(), isn't ? What's
wrong with this workaround ?
