help

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.
