2023-08-21hwmon: pmbus: Fix -EIO seen on pli1209Patrick Rudolph
After doing performance optimizations the pli1209 driver failed to probe with a probabilty of 2%. It wasn't able to read the PMBUS_OPERATION register due to an -EIO error. An investigation showed that the PLI1209 takes 230 usec to execute the CLEAR_FAULTS command. During that time it's busy and NACKs all requests on the SMBUS interface. It also NACKs reads on PMBUS_STATUS_BYTE making it impossible to poll the BUSY flag. Add a custom write_data function to just wait for not BUSY unconditionally after sending a CLEAR_FAULTS command. TEST: Verified using an I2C bus analyser that no more NACKs are seen after sending a CLEAR_FAULTS command.

2023-08-21hwmon: (hp-wmi-sensors) Initialize pevents in hp_wmi_sensors_init()James Seo
The following warning is given by the Smatch static checker: drivers/hwmon/hp-wmi-sensors.c:1937 hp_wmi_sensors_init() error: uninitialized symbol 'pevents'. If there are no instances of the HPBIOS_PlatformEvents WMI object available, init_platform_events() never initializes this pointer, which may then be passed to hp_wmi_debugfs_init() uninitialized. The impact should be limited because hp_wmi_debugfs_init() uses this pointer only if the count of HPBIOS_PlatformEvents instances is _not_ zero, while conversely, it will be uninitialized only if the count of such instances _is_ zero. However, passing it uninitialized still constitutes a bug.

2023-08-21hwmon: (pmbus/mp2975) Add support for MP2971 and MP2973Patrick Rudolph
Add support for MP2971 and MP2973, the successor of MP2975. The major differences are: - On MP2973 and MP2971 the Vref cannot be read and thus most of the OVP/current calculations won't work. - MP2973 and MP2971 also support LINEAR format for VOUT - MP2973 and MP2971 do not support OVP2 - On MP2973 and MP2971 most registers are in LINEAR format - The IMVP9_EN bit has a different position - Per phase current sense haven't been implemented. As on MP2975 most of the FAULT_LIMIT and WARN_LIMIT registers have been redefined and doesn't provide the functionality as defined in PMBUS spec. Tested on MP2973 and MP2971.

2023-08-21hwmon: (pmbus/mp2975) Simplify VOUT codePatrick Rudolph
In order to upstream MP2973/MP2971 simplify the code by removing support for various VOUT formats. The MP2973 and MP2971 supports all PMBUS supported formats for VOUT, while the MP2975 only support DIRECT and VID for VOUT. In DIRECT mode all chips report the voltage in 1mV/LSB. Configure the chip to use DIRECT format for VOUT and drop the code conversion code for other formats. The to be added chips MP2973/MP2971 will be configured to also report VOUT in DIRECT format. The maximum voltage that can be reported in DIRECT format is 32768mV. This is sufficient as the maximum output voltage for VR12/VR13 is 3040 mV.

2023-08-21hwmon: (nct6775) Increase and reorder ALARM/BEEP bitsAhmad Khalifa
* Increase available bits, IN: 16 to 24, FAN: 8 to 12, TEMP: 6 to 12 * Reorder alarm/beep definitions to match in order to allow additional inputs in the future * Remove comments about 'unused' bits as probe() is a better reference Testing note: * Tested on nct6799 with IN/FAN/TEMP, and changing min/max/high/hyst, that triggers the corresponding alarms correctly. Good confirmation on the original mapping of the registers and masks. As to be expected, only 4 fans and 2 temps (fixed) have limits currently on nct6799 on my board. * Trouble with testing intrusion alarms and beeps, no way to confirm those. As I understand now, intrusion/caseopen is probably not connected on my board. And I haven't seen a buzzer on a board in ages.

2023-08-21hwmon: Remove smm665 driverGuenter Roeck
SMM665 and related chips are power controller/sequencer chips from Summit Microelectronics. The company was acquired by Qualcomm in 2012, and support for the chip series stopped. The chips are long since gone from active use, making the driver unsupportable and just consuming space and compile time. Remove it. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
