2022-07-13hwmon: (aquacomputer_d5next) Move device-specific data into struct aqc_dataAleksa Savic1-152/+92
As preparation for adding support for more devices in upcoming patches, move device-specific data, such as number of fans, temperature sensors, register offsets etc. to struct aqc_data. This is made possible by the fact that the supported Aquacomputer devices share the same layouts of sensor substructures. This allows aqc_raw_event() and others to stay general and not be cluttered with similar loops for each device.

2022-07-13hwmon: (asus_wmi_sensors) Save a few bytes of memoryChristophe JAILLET1-7/+5
The first 'for' loop of asus_wmi_configure_sensor_setup() only computes the number and type of sensors that exist in the system. Here, the 'temp_sensor' structure is only used to store the data collected by asus_wmi_sensor_info(). There is no point in using a devm_ variant for this allocation. This wastes some memory for no good reason. Use the stack instead.

2022-07-13hwmon: (lm90) Use worker for alarm notificationsGuenter Roeck1-5/+13
Reporting alarms using hwmon_notify_event() may result in a callback from the thermal subsystem. This means that such notifications must not hold the update lock to avoid a deadlock. To avoid this situation, use a worker to handle notifications.

2022-07-13hwmon: (dell-smm) Improve assembly codeArmin Wolf1-60/+18
The new assembly code works on both 32 bit and 64 bit cpus and allows for more compiler optimisations. Since clang runs out of registers on 32 bit x86 when using CC_OUT, we need to execute "setc" ourself. Also modify the debug message so we can still see the result (eax) when the carry flag was set. Tested with 32 bit and 64 bit kernels on a Dell Inspiron 3505.

2022-07-13hwmon: (pmbus/ltc2978) Set voltage resolutionMårten Lindahl2-6/+46
The LTC2977 regulator does not set the regulator_desc .n_voltages value which is needed in order to let the regulator core list the regulator voltage range. This patch defines a regulator_desc with a voltage range, and uses it for defining voltage resolution for regulators LTC2972/LTC2974/LTC2975/ LTC2977/LTC2978/LTC2979/LTC2980/LTM2987 based on that they all have a 16 bit ADC with the same stepwise 122.07uV resolution. It also scales the resolution to a 1mV resolution which is easier to handle.

2022-07-13hwmon: (pmbus) Add list_voltage to pmbus opsMårten Lindahl1-0/+30
When checking if a regulator supports a voltage range, the regulator needs to have a list_voltage callback set to the regulator_ops or else -EINVAL will be returned. This support does not exist for the pmbus regulators, so this patch adds pmbus_regulator_list_voltage to the pmbus_regulator_ops.

2022-07-13hwmon: (pmbus) Introduce and use cached vout marginsMårten Lindahl1-17/+61
When setting a new voltage the voltage boundaries are read every time to check that the new voltage is within the proper range. Checking these voltage boundaries consists of reading one of PMBUS_MFR_VOUT_MIN/ PMBUS_VOUT_MARGIN_LOW registers and then PMBUS_MFR_VOUT_MAX/ PMBUS_VOUT_MARGIN_HIGH together with writing the PMBUS_CLEAR_FAULTS register. Since these boundaries are never being changed, it can be cached and thus saving unnecessary smbus transmissions.

MAX6642 is a reduced version of LM90 with no low limits and no conversion rate register. Its alert functionality is broken, similar to many other chips supported by the lm90 driver.
