Temperures of up to 12 thermal zones are traced to ftrace by polling. The poll interval can be set by defining CONFIG_POLL_INTERVAL_MS during build, which defaults to 100 ms. It will be clamped to be between 1 and 5000 ms inclusive.
Thermal zones are selected by defining CONFIG_THERMAL_ZONE_LIST with a comma-separated list of thermal zone types (the value of /sys/class/thermal/thermal_zoneX/type) during build, otherwise, LITTLE,MID,BIG is used.
