I'm sorry to send the empty mail without any content.

I repiled the touchkey driver against compatible name.
Usually, when developing the device driver, we use the specific h/w name
but in this patch, the touckey dt node uses the h/w board name instead of
original touckhey name.

If this touckey device is used on other h/w board, I think the current
compatible name
is not proper.

So. please drop the my reviewed-by tag until completing the discussion.
I'm sorry to make the confusion.
