[PATCH v2 0/2] ARM: dts: samsung: exynos4412-midas: fix key-ok and use Linux event codes

[Raymond Hackley]

Input event code 139 stands for KEY_MENU, instead of KEY_OK as node name
key-ok inplies. Fix it with correct event code 0x160.

Use event codes with linux-event-codes.h included for input keys on midas
in addition.

I applied this and was about to send in pull request, but it does not
seem right, sorry. The button was always called "menu" button. Why
changing it to OK? Just because of node name? The node name does not
matter, this could be called "key-1" as well..

Best regards,
Krzysztof

Hi Krzysztof,

This key-ok is the hardware middle button on midas, and there is also
touchkey, which already provides <KEY_BACK KEY_MENU>, so I assume the other
KEY_MENU in key-ok is duplicated. Fixing it with KEY_OK as the node name
implies would make more sense.

Regards,
Raymond

Ah, ok, that makes sense.

Applied, thanks!

It is however very late in the cycle, so there is a chance this will miss the
merge window. If this happens, I will keep it for the next cycle (no need for
resending).
