[PATCH 0/6] Add support for MAX20830C and MAX20840C step-down DC-DC switching regulator

From: Alexis Czezar Torreno

Date: Mon Jun 29 2026 - 22:47:35 EST


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

Patches 1 and 2 adds an enable gpio that should have been included before.

Patches 3 and 4 adds new resistor feedback properties that is needed to
properly scale VOUT

Patches 5 and 6 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.
