Only the temp sensors that I can verify are present. T_Sensor is the temperature reading of a 10kΩ β=3435K NTC thermistor optionally connected to the T_SENSOR header. The other sensors are as found on the X670E Hero. Signed-off-by:

The INA3221 allows the Critical alert pin to be controlled by the summation control function. This function adds the single shunt-voltage conversions for the desired channels in order to compare the combined sum to the programmed limit. The Shunt-Voltage Sum Limit register contains the programmed value that is compared to the value in the Shunt-Voltage Sum register in order to determine if the total summed limit is exceeded. If the shunt-voltage sum limit value is exceeded, the Critical alert pin pulls low. For the summation limit to have a meaningful value, we have to use the same shunt-resistor value on all included channels. Unless equal shunt-resistor values are used for each channel, the summation control function cannot be used and it is not enabled by the driver. To address this, add support to disable the summation of specific channels via device tree property "ti,summation-disable". The channel which has this property would be excluded from the calculation of summation control function. For example, summation control function calculates Shunt-Voltage Sum as: - input_shunt_voltage_summation = input_shunt_voltage_channel1 + input_shunt_voltage_channel2 + input_shunt_voltage_channel3 If we want the summation to only use channel1 and channel3, we can add 'ti,summation-disable' property in device tree node for channel2. Then the calculation will skip channel2. - input_shunt_voltage_summation = input_shunt_voltage_channel1 + input_shunt_voltage_channel3 Note that we only want the channel to be skipped for summation control function rather than completely disabled. Therefore, even if we add the property 'ti,summation-disable', the channel is still enabled and functional. Finally, create debugfs entries that display if summation is disabled for each of the channels. Signed-off-by:Rajkumar Kasirajan <rkasirajan@nvidia.com> Signed-off-by:

The INA3221 has a critical alert pin that can be controlled by the summation control function. This function adds the single shunt-voltage conversions for the desired channels in order to compare the combined sum to the programmed limit. The Shunt-Voltage Sum Limit register contains the programmed value that is compared to the value in the Shunt-Voltage Sum register in order to determine if the total summed limit is exceeded. If the shunt-voltage sum limit value is exceeded, the critical alert pin pulls low. For the summation limit to have a meaningful value, it is necessary to use the same shunt-resistor value on all included channels. Add a new vendor specific property, 'ti,summation-disable', to allow specific channels to be excluded from the summation control function if the shunt resistor is different to other channels or the channel should not be considered for triggering the critical alert pin. Note that the ina3221 has always supported summing the various input channels and summation is enabled by default if the shunt-resistor values are the same. This change simply provides a way to exclude inputs from the summation. If this property is not populated, then the functionality of the driver does not change. Signed-off-by:

Used enums and while loops to replace switch for selecting and getting update interval from conversion rate bits. Divided the write_alarm_val function into 2 functions. The new function is more generic: it can be used not only for alarm writes, but for any kind of writes which require the device to be in shutdown mode. Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
