Can magic numbers be replaced with defines?
Fine, will do in V3.

What does this call to palmas_update_bits do?

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
