[PATCH 00/11] Add support for the TI BQ25792 battery charger

[Alexey Charkov]

This adds support for the TI BQ25792 battery charger, which is similar in
overall logic to the BQ25703A, but has a different register layout and
slightly different lower-level programming logic.

The series is organized as follows:
- Patch 1 adds the new variant to the existing DT binding, including the
  changes in electrical characteristics
- Patches 2-4 are minor cleanups to the existing BQ25703A OTG regulator
  driver, slimming down the code and making it more reusable for the new
  BQ25792 variant
- Patch 5 is a logical fix to the BQ25703A clamping logic for VSYSMIN
  (this is a standalone fix which can be applied independently and may be
  backported to stable)
- Patches 6-8 are slight refactoring of the existing BQ25703A charger
  driver to make it more reusable for the new BQ25792 variant
- Patch 9 adds platform data to distinguish between the two variants in
  the parent MFD driver, and binds it to the new compatible string
- Patches 10-11 add variant-specific code to support the new BQ25792
  variant in the regulator part and the charger part respectively,
  selected by the platform data added in patch 9
