ENGR00155627-1 [MX6]Add thermal cooling devie
1.Common code of thermal_sys has some bug,could
not set the mode via sysfs using echo enable/disabled
command;
2.Since the anatop thermal formula still not accurate,
in order to help test and adjust the trip point of
anatop thermal zone, we add the set trip point temp
value into the sysfs interface.
