I still think that sensor devices in general are better suited to IIO subsystem and I hope it will get out of staging soon. Once it is out of staging we may think about creating a IIO-to-input bridge (copuld be either in kernel or a userspace solution based on uinput) to route sensors that are indeed used as HIDs. Hope this makes sense. -- Dmitry
