[PATCH V3 1/1] input: gpio-keys: add support for disable button from DT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add support to disable the button from DT via status property
if given button is not supporting on given platforms.

This will help to re-use the existing dtsi file with status
enable/disable across platforms.
