My guess is that it triggers regulator idle modes in the PMIC based
on the SoC off mode. There's no documentation for this thing..
I've just kept what the Motorola Linux kernel tree does here and added
some comments to CPCAP_REG_OFF_MODE_SEC.
I'll address the rest of the comments and post v2, thanks for looking.

Tony
