Thanks a lot for the clarification. This was not evident to me when I read the
PMIC datasheet and because both the max77xxx Chrome OS 3.8 and mainline max77686
drivers used a simplistic model of the power scheme.

But Doug confirmed to me that some regulators on this PMIC do indeed use others
regulators as a power supply so I'll change this in the next version of the
patch-set.

Best regards,
