-Subject: [PATCH] input: Add new sun4i-ts 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.
