[PATCH 2/2] input: gpio-keys: add support to name the gpio-keys

Show all headers | View raw

Add support from DT to name the gpio-keys driver to have
desired key name for this input system.

This helps userspace code to get name and perform proper
event to key mapping in some of cases. In android, the
user space map the key code to application code using
key character layout and for this it uses the name of
input system.
