以msm8953的themal分布信息，主要是下图的位置：
这其中 cpu相关的themal的位置有：
读取thermal 温度数据可以通过以下几个步骤：
获取sensor_info
root@msm8953_64:/ # cat /sys/module/msm_thermal/sensor_info
tsens:tsens_tz_sensor0::10
tsens:tsens_tz_sensor1::10
tsens:tsens_tz_sensor2:pop_mem:10
tsens:tsens_tz_sensor3::10
tsens:tsens_tz_sensor4:cpu4:10
tsens:tsens_tz_sensor5:cpu5:10
tsens:tsens_tz_sensor6:cpu6:10
tsens:tsens_tz_sensor7:cpu7:10
tsens:tsens_tz_sensor8:L2_cache_1:10
tsens:tsens_tz_sensor9:cpu0:10
tsens:tsens_tz_sensor10:cpu1:10
tsens:tsens_tz_sensor11:cpu2:10
tsens:tsens_tz_sensor12:cpu3:10
tsens:tsens_tz_sensor13:L2_cache_0:10
tsens:tsens_tz_sensor14::10
tsens:tsens_tz_sensor15:gpu:10
alarm:pm8953_tz::1000
adc:pa_therm0::1
adc:pa_therm1::1
adc:xo_therm::1
adc:xo_therm_buf::1
adc:case_therm::1
在/sys/class/thermal/ 路径下可以看到所有的thermal_zone
msm8953_64:/sys/class/thermal # ls
thermal_zone0 thermal_zone11 thermal_zone14 thermal_zone17 thermal_zone2 thermal_zone22 thermal_zone4 thermal_zone7
thermal_zone1 thermal_zone12 thermal_zone15 thermal_zone18 thermal_zone20 thermal_zone23 thermal_zone5 thermal_zone8
thermal_zone10 thermal_zone13 thermal_zone16 thermal_zone19 thermal_zone21 thermal_zone3 thermal_zone6 thermal_zone9
那么怎么知道具体的温度信息就需要结合上面的sensor_info来对比分析了。
先获取所有的tmpe信息：

pa_therm0

xo_therm_buf
case_therm
chg_temp
tsens_tz_sensor1
tsens_tz_sensor2
tsens_tz_sensor3
tsens_tz_sensor4
这3者信息相结合，即可得到该thermal的温度信息；
举一个例子：
thermal_zone10 –> tsens_tz_sensor5 -> 309
在sensor_info中这个节点的信息是tsens:tsens_tz_sensor5:cpu5:10
最后的10 表示比例是1：10，也就是表示309是表示cpu5的温度是30.9摄氏度。
