RFC: Adding support for other usages

Hi,

I noticed that HID Usage And Descriptions specifications contains many more usages than currently supported by the kernel. At the moment I'm concerned exclusively about digitizers.

Taking as an example usage 0x0f (Capacitive Heat Map Digitizer), should support for that be added to hid-multitouch.c or should we have a new hid-heat-map.c driver? Any suggestions?

Best regards
