From 2cefdb1f0a27150755ef2730bafc58bf2ed16571 Mon Sep 17 00:00:00 2001 From: Nick Dyer Date: Sun, 18 May 2014 22:59:20 -0700 Subject: Input: atmel_mxt_ts - remove unnecessary platform data It is not necessary to download these values to the maXTouch chip on every probe, since they are stored in NVRAM. It makes life difficult when tuning the device to keep them in sync with the config array/file, and requires a new kernel build for minor tweaks. These parameters only represent a tiny subset of the available configuration options, tracking all of these options in platform data would be a endless task. In addition, different versions of maXTouch chips may have these values in different places or may not even have them at all. Having these values also makes life more complex for device tree and other platforms where having to define a static configuration isn't helpful.

The matrix size is not used for anything, and results in some rather confusing code to re-read it because it may change when configuration is downloaded, so don't print it out.
