From a636df9673e1e4627722777fe6075943372e76be Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Mon, 27 Jul 2015 17:26:38 -0700 Subject: [PATCH] Input: tsc2005 - improve readability of register defines Improve defines for first control byte by removing 0x00 prefix (the defines are for 8 bit values and not for 16 bit values) and expose register structure by exposing the shift.
