Subject: [PATCH 01/11] dt-bindings: mfd: ti,bq25703a: Expand to include BQ25792
Date: Tue, 03 Mar 2026 19:32:46 +0400	[thread overview]
Message-ID: <20260303-bq25792-v1-1-e6e5e0033458@flipper.net> (raw)
In-Reply-To: <20260303-bq25792-v1-0-e6e5e0033458@flipper.net>

TI BQ25792 is similar in operation to BQ25703A, but has a different
register layout and different current/voltage capabilities.

Expand the existing BQ25703A binding to include BQ25792, and move the
voltage and current limits into per-variant conditional statements.
