The R-Car Thermal driver fixes have been tested on R-Car M2-W and R-Mobile APE6. The DA9062/9061 fixes have been compile-tested only. Changes compared to v1: - Add Reviewed-by. Note: The Intel PowerClamp driver also uses schedule_delayed_work(), but I believe that is OK, as the thermal registers are part of the CPU. Thanks!
