Nitpicking: there is usually a "*" at the beginning to give it a
title-ish look ;-)

I think that you need to replace by a generic name for the node name:
qt1070: keyboard@1b {
compatible = "atmel,qt1070";

};
I found "keyboard" to be the most appropriate in the ePAPR.

Otherwise, looks good. So, if you agree on my comments and for next
