Hi Jiri, well, we tried yesterday to make all those things working, but the Haswell platform I was able to have access was not very cooperative. So I wasn't able to test the whole autodetection mechanism through ACPI (I even not managed to communicate with the various HID over i2c devices that were available to test). However, Mika managed to test this ACPI stuff, and he is able to retrieve the HID descriptor address. Given that, I think it's safe to include it right now. There will still be the last point with the gpios, but it will come when someone get access to a device presenting this feature.
