| |
The MUIC block in max77693 has different I2C address than PMIC. The driver allocated two regmaps: for PMIC and MUIC. However it used the same regmap_config (with max_register field) for both regmaps. Actual maximum address of register for MUIC is different than for PMIC.
Define another regmap_config for MUIC with proper max_register value.
