[PATCH 1/2] dt-bindings: power: supply: bq27xxx: add BQ28Z620

From: Alexey Charkov

Date: Fri Oct 02 2026 - 08:05:56 EST


Add a compatible for the TI BQ28Z620, a firmware derivative of the
BQ28Z610 that keeps its standard command set but drops the Battery Trip
Point feature and relocates much of the data flash as a result.

Keep it standalone rather than falling back to ti,bq28z610, as software
programming the BQ28Z610 data flash layout would corrupt the
configuration of a BQ28Z620.
