I'd rather not change the behavior of the upstream driver because that would break other things. It would be better to just fix the Android framework code for the device you are shipping. What is it about Gingerbread that causes problems with hover? Is it the fact it isn't checking BTN_TOUCH or the fact that it doesn't care when ABS_MT_PRESSURE == 0? (Is BTN_TOUCH still relevant to the MT protocol or only in single-touch?) I have already added hover support to Android. It will appear in an upcoming release, along with support for the MT slots protocol "B". Sending a non-zero ABS_MT_DISTANCE is also a good robust hint for hover. Zero pressure can be ambiguous sometimes. Who did you talk to at Google about this?
