Subject[PATCH] power: supply: bq27xxx_battery: Fix register map for BQ27510 and BQ27520
Message-ID<szRzc-5pA-19@gated-at.bofh.it>
The BQ27510 and BQ27520 use a slightly different register map than the
BQ27500, add a new type enum and add these gauges to it.

Fixes: d74534c27775 ("power: bq27xxx_battery: Add support for additional bq27xxx family devices")
