I've enabled the generic cpufreq support, we had it disabled as when
it first landed it had problems.
The BBB is booting with 3.13rc8 with no patches but there's a few
issues I need to resolve this week with USB so I'll review that for
the BB patchset to make sure it's there. Is it queued to go upstream
for 3.14?
3.14 is closed, I'm cleaning my patches listed in that repo and
planning to post to l-a/l-o after v3.14-rc1 hits..
Talking with CircuitCo, they would prefer the default pinmux to be
setup like so:

So i'm adding those changes to the push too..
