x-powers,dcdc-workmode:
$ref: /schemas/types.yaml#/definitions/uint32
enum: [0, 1]
description: >
Only valid for DCDC regulators. Setup 1 for PWM mode, 0
for AUTO (PWM/PFM) mode. The DCDC regulators work in a
mixed PWM/PFM mode, using PFM under light loads and
switching to PWM for heavier loads. Forcing PWM mode
trades efficiency under light loads for lower output
noise. This probably makes sense for HiFi audio related
applications that aren't battery constrained.
