[PATCH 06/11] power: supply: bq257xx: Make the default current limit a per-chip attribute
From: Alexey Charkov
Date: Tue Mar 03 2026 - 10:41:25 EST
Add a field for the default current limit to the bq257xx_info structure and
use it instead of the hardcoded value in the probe function.
This prepares the driver for allowing different electrical constraints for
different chip variants.
