From 6decea7c5438e2955f64e2513ec9a2fac7602a7d Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 14 May 2014 11:20:45 -0700 Subject: Input: add driver for Allwinner sunxi SoC's rtp controller Note the sun4i-ts controller is capable of detecting a second touch, but when a second touch is present then the accuracy becomes so bad the reported touch location is not useable. The original android driver contains some complicated heuristics using the aprox. distance between the 2 touches to see if the user is making a pinch open / close movement, and then reports emulated multi-touch events around the last touch coordinate (as the dual-touch coordinates are worthless). These kinds of heuristics are just asking for trouble (and don't belong in the kernel). So this driver offers straight forward, reliable single touch functionality only.
