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, Javier
