Config: https://github.com/beagleboard/kernel/blob/beaglebone-3.6/patches/configs/beaglebone

I rebased onto latest mainline and refreshed the base patches from Vaibhav and I now get: 

[    0.246796] tps65217 0-0024: TPS65217 ID 0xf version 1.1

So it boots! I don't know what made it break before, but it's working now :)
