Thanks Mika for the pointers. I have looked at the documentation.

we already have i2c driver for battery monitoring but the chip needs initialized with
characterization data. We wanted to populate/pass this data through ACPI table to the
i2c slave driver.

How can I do that? Can I pass characterization data through ACPI table to the i2c slave device?
