This deletes the ABx500 hwmon driver, the only supported variant being the AB8500. This driver has been replaced by generic frameworks. By inspecting the abx500 sysfs files we see that it contains things such as temp1_max, temp1_max_alarm, temp1_max_hyst, temp1_max_hyst_alarm, temp1_min, temp1_min_alarm. It becomes obvious that the abx500.c is a reimplementation of thermal zones. This is not very strange as the generic thermal zones were not invented when this driver was merged so people were rolling their own. The ab8500.c driver contains conversion tables for handling a thermistor on ADC channels AUX1 and AUX2. I managed to replace the functionality of the driver with: - Activation of the ntc_thermistor.c driver, CONFIG_SENSORS_NTC_THERMISTOR - Activation of thermal zones, CONFIG_THERMAL - In the device tree, connecting the NTC driver to the processed IIO channels from the AB8500 GPADC ADC forming two instances of NTC sensors. - Connecting the two NTC sensors to a "chassis" thermal zone in the device tree and setting that to hit the CPU frequency at 50 degrees celsius and do a critical shutdown at 70 degrees celsius, deploying a policy using the sensors. After talking to the original authors we concluded that the driver was never properly parameterized in production so what we now have in the device tree is already puts the thermistors to better use than what the hwmon driver did. The two remaining channels for two battery temperatures is already handled in the charging algorithms but can be optionally extended to thermal zones as well if we want these to trigger critical shutdown for the platform.
