I have the same issue with TPS62361 on Palmas -> GPIO controls the voltage register supplying MPU, without any driver setting things up, GPIO gets reset and obviously voltage value switches to an voltage where device does not function. Solution I am working on to solve this is [1]: snippet is part of a patch that I am working on atm. This is the right way to do it IMHO. Will allow the driver to exist when HWMOD will be eventually replaced by some other framework.
