From f907b7642860d984beddcf10ff686a8636202087 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Thu, 21 May 2015 09:09:58 +0800 Subject: MLK-11035 imx: mx6 update thermal slope factors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From temp sensor guys: " I confirmed the math with him(had do the accuracy study) today. The new, final equation is: Tmeas = (Nmeas - n1) / slope + t1 + offset n1= fused room count t1= 25 offset=3.580661 slope= 0.4148468 – 0.0015423*n1 " 87723f903454aaf17336e0fe9098ea7911c19f3c update the thermal with not accurate slope parameters. This patch fix it.
