[PATCH v2 2/3] dt-bindings: power: supply: pm8941-coincell: Don't require charging properties

From: Konrad Dybcio
Date: Tue Feb 14 2023 - 04:10:40 EST


It's fine for these properties to be absent, as the driver doesn't fail
without them and functions with settings inherited from the reset/previous
stage bootloader state.
