[PATCH v2 0/5] Add support for MAX20830C and MAX20840C step-down DC-DC switching regulator

[Alexis Czezar Torreno]

This series adds a few features before adding support to MAX20830C and
MAX20840C.

Patch 1 adds an enable gpio property that should have been included before.

Patches 2 and 3 adds new resistor feedback properties that is needed to
properly scale VOUT

Patches 4 and 5 adds support for devices MAX20830C and MAX20840C.

MAX20830C and MAX20840 are step-down DC-DC switching regulator with PMBus
interface. MAX20830C is a different packaging for MAX20830, and MAX20840C
supports 40A regulation compared to MAX20830 that is only 30A.

Changes in v2:
- Patch 1/5: completing example
- Dropped patch adding GPIO enable in driver (no use case)
- Patch 3/5: added notes on READ_VOUT and related VOUT commands
- Patch 4/5: removed comment on fallback
- Patch 5/5: simplified device ID check handling
