In that case you should probably consider using regmap_register_patch() for corrections to the default registers in sm8250 case.

As regmap_register_patch() not working in this use case, updating defaults in probe for sc7280 specific differences.

In what way is regmap_register_patch() not working?

Even after using this API, reg cache is not updating with the latest default values.

The regmap_register_patch() implementation is bypassing Cache and writing values to HW.

The requirement for updating previous defaults in cache is not solving here.
