thermal: stm32: Fix low threshold interrupt flood

2020-01-27T14:40:26+00:00

With the STM32 thermal peripheral, it is not possible to dump the temperature that has caused the interrupt. When the temperature reaches the low threshold, we generally read a temperature that is a little bit higher than the low threshold. This maybe due to sampling precision, and also because the CPU becomes hotter when it quits WFI mode. In that case, the framework does not change the trip points. This leads to a lot of low threshold interrupts. The fix is to set the low threshold value 0.5 degrees Celsius below the actual request. The problem is not so frequent with the high threshold and it would no be a good idea to set the threshold value higher than the request.

Change the way of computing to avoid rounds by 1 or 2 degrees. Also simplify the sampling time management that is hard-coded to maximum value during probe. Signed-off-by: Pascal Paillet Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/20200110101605.24984-6-p.paillet@st.com

thermal: stm32: Handle multiple trip points

2020-01-27T14:40:16+00:00

Let the thermal framework handle the trip points instead of custom code inside the driver. This is backward compatible, simplifies the driver and offers the possibility to the user to set any trip point he needs. stm_thermal_set_trips callback that is registered to set_trips ops to handle the low and high thresholds and replaces stm_thermal_set_threshold and stm_thermal_update_threshold functions. modify irq enable to handle the thresholds.
