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.
