OMAP EHCI having clock problems?

[Kevin Hilman <khilman@linaro.org>]

Felipe, Roger,

Using Tony's current master branch, and enabling EHCI support, I see 
the clock framework spitting loudly about the EHCI driver (full boot log
below.)   The same thing happens on v3.8-rc7.

Any idea what's going on?  Am I missing a set of fixes that's already
been posted?

On a related note, is anyone planning to fix the runtime PM problems in
this driver?  It's still disabled by default in omap2plus_defconfig
because the driver keeps CORE from hitting retention, even when no
devices are attached.

Kevin
