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. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com>
Applied, thank you.
