Unfortunately on all of them Atmel parts assigned names ATML0000 and ATML0001, and do not carry any other configuration data. So let's create generic instance of platform data that should cover most of them (we assume that they will not be using T100 objects, since with those Google mapped BTN_LEFT onto a different GPIO, so slightly different keymap would be needed, but I think we used parts with T100 on ARM devices where we thankfully have DTS and can describe the devices better).
