- This library provides a runtime debugfs interface to read and write a
- subset of regmap registers. This interface is more performant and
- easier to use than the traditional method which dumps all registers
- defined in a given regmap.

- help
- Say 'y' here to allow regmap debugfs writes within the QTI debugfs
- regmap library. Regmap debugfs write could be risky when accessing
- essential hardware components, so it is not recommended to enable this
- option on production devices.
