[U-Boot] [PATCH v3 28/35] dm: power: Convert as3722 to driver model

12 Jun 2017

Convert this PMIC driver to driver model and fix up other users. The
regulator and GPIO functions are now handled by separate drivers.
Update nyan-big to work correct. Three boards will need to be updated by
the maintainers: apalis-tk1, jetson-tk1, cei-tk1-som
