You need to submit a bindings patch to document your "ilitek,ili9882t" compatible string. 2. I would tend to add the support to the "i2c-hid-of-elan.c" driver instead of the goodix one. Probably the drivers need to combined again (I'll see if I can post a patch for that before too long), but if I were picking one I'd pick the elan one, I think. -Doug
