This APIs update the selected bits based on mask. This is wrapper over the regmap_update_bits() to provide the interface at the Palmas register access. The palmas registers are paged on different i2c address and offset. The i2c address and offset is decided based on base_address and offset. This APIs does all calculation to get the correct i2c slave address and offset address based on argument. >> +static int palmas_clks_remove(struct platform_device *pdev) >> +{ >> + of_clk_del_provider(pdev->dev.of_node); > I'll be taking Sylwester's clock deregistration series after he > publishes the next version, so if you want to call clk_unregister here > (based on the new call) you could. > > If you want to add that in a later patch it is OK. Thanks for pointing me this changes. I like to add this on my follow on (later) patch, not on this. -- 1.7.1.1
