One small fix didn't get sent before the merge window.
2023-10-30regmap: Merge up fix for window/paging issueMark Brown3-2/+33
This was too late and could potentially impact too many drivers for me to be comfortable sending it before the merge window.

2023-10-29hwmon: (aquacomputer_d5next) Add support for Aquacomputer High Flow USB and ↵Aleksa Savic2-4/+70
MPS Flow Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer High Flow USB flow sensor, which communicates through a proprietary USB HID protocol. This commit also adds support for the sensors of the MPS Flow devices, as they have the same USB product ID and sensor layouts. Implemented by Leonard Anderweit [1]. Internal and external temp sensor readings are available, along with the flow sensor. Additionally, serial number and firmware version are exposed through debugfs.

Add support for LTC2991 Octal I2C Voltage, Current, and Temperature Monitor. The LTC2991 is used to monitor system temperatures, voltages and currents. Through the I2C serial interface, the eight monitors can individually measure supply voltages and can be paired for differential measurements of current sense resistors or temperature sensing transistors. Additional measurements include internal temperature and internal VCC.

2023-10-28hwmon: (pmbus/max31785) Add delay between bus accessesLakshmi Yadlapati1-21/+167
The MAX31785 has shown erratic behaviour across multiple system designs, unexpectedly clock stretching and NAKing transactions. Experimentation shows that this seems to be triggered by a register access directly back to back with a previous register write. Experimentation also shows that inserting a small delay after register writes makes the issue go away. Use a similar solution to what the max15301 driver does to solve the same problem. Create a custom set of bus read and write functions that make sure that the delay is added.

2023-10-28hwmon: (ina3221) Add support for channel summation disableNinad Malwade1-3/+30
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.

2023-10-28dt-bindings: hwmon: ina3221: Add ti,summation-disableJon Hunter1-0/+19
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.

Convert the TI INA3221 bindings from the free-form text format to json-schema. Note that the INA3221 input channels default to enabled in the chip. Unless channels are explicitly disabled in device-tree, input channels will be enabled.
