MLK-11035 imx: mx6 update thermal slope factors
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. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>
