This patch expands the thermal information to the limits of 90 and 105 for alert and critical. For boards who never use industrial temperatures, these can be changed on their respective device trees with something like: &cpu_alert0 { temperature = <85000>; /* millicelsius */ }; &cpu_crit { temperature = <90000>; /* millicelsius */ }; Signed-off-by: Adam Ford Tested-by: H.
