The Logic PD Torpedo dm3730 boots with a few messages that concern me:

vdd_mpu_iva

The current device tree shows the arm is powered by VCC.

I noticed that abb_mpu_iva has a bunch of OPP's, but it's not clear to
me how or what should power this and/or how the regulator is is
related (if at all)
The torpedo is using the TWL4030 PMIC, and I would expect those
voltages to be acceptable to the twl4030
