2024-07-14hwmon: (max6697) Fix swapped temp{1,8} critical alarmsGuenter Roeck1-2/+2
The critical alarm bit for the local temperature sensor (temp1) is in bit 7 of register 0x45 (not bit 6), and the critical alarm bit for remote temperature sensor 7 (temp8) is in bit 6 (not bit 7).

2024-07-10hwmon: (g762) Initialize fans after configuring clockGuenter Roeck1-4/+6
Adding support for G761 included adding support for an internal clock. Enabling the internal clock requires setting a bit in the FAN_CMD2 register. This is implemented in g762_fan_init(). However, g762_fan_init() is called before clock support is selected, and the flag indicating that the internal clock should be used is not yet set. Initialize the clock before initializing the fan to solve the problem. While at it, also add "g7621" to the i2c_device_id array.

2024-07-08hwmon: (amc6821) Convert to use regmapGuenter Roeck2-444/+384
Use regmap for register accesses and caching. While at it, use sysfs_emit() instead of sprintf() to write sysfs attribute data, and remove spurious debug messages which would only be seen as result of a bug in the code. Also make sure that error codes are propagated and not replaced with -EIO. While at it, introduce rounding of written temperature values and for internal calculations to reduce deviation from written values and as much as possible.

2024-07-08hwmon: (amc6821) Make reading and writing fan speed limits consistentGuenter Roeck1-4/+9
The default value of the maximum fan speed limit register is 0, essentially translating to an unlimited fan speed. When reading the limit, a value of 0 is reported in this case. However, writing a value of 0 results in writing a value of 0xffff into the register, which is inconsistent. To solve the problem, permit writing a limit of 0 for the maximim fan speed, effectively translating to "no limit". Write 0 into the register if a limit value of 0 is written. Otherwise limit the range to <1..6000000> and write 1..0xffff into the register. This ensures that reading and writing from and to a limit register return the same value while at the same time not changing reported values when reading the speed or limits. While at it, restrict fan limit writes to non-negative numbers; writing a negative limit does not make sense and should be reported instead of being corrected.

2024-07-08hwmon: (amc6821) Stop accepting invalid pwm valuesGuenter Roeck1-6/+8
The pwm value range is well defined from 0..255. Don't accept any values outside this range. This changes the valid range of pwm1_auto_point2_pwm from 0..254 to 0..255, meaning it can now be equivalent to not only pwm1_auto_point1_pwm (which is always 0) but also to pwm1_auto_point3_pwm (which is always 255). While that may not be practical, there seems to be no technical reason for preventing a user from doing it.

This should aid with upstream support of a range of higher performance ADCs and DACs. Two merges from other trees - spi/spi_devm_optimize used for simplification in ad7944. - dmaengine/topic_dma_vec to enable the DMABUF series. One feature with impact outside IIO. - Richer set of dev_err_probe() like helpers to cover ERR_PTR() cases. New device support ================== adi,ad7173 - Add support for AD4111, AD4112, AD4114, AD4115 and ADC4116 pseudo differential ADCs. Major driver rework was needed to enabled these. adi,ad7944 - Use devm_spi_optimize_message() to avoid a local devm cleanup callback. This is the example case from the patch set, others will follow. mediatek,mt6359-auxadc - New driver for this ADC IP found in MT6357, MT6358 and MT6359 PMICs. st,accel - Add support for the LIS2DS12 accelerometer ti,ads1119 - New driver for this 16 bit 2-differential or 4-single ended channel ADC. Features ======== dt-bindings - Introduce new common-mode-channel property to help handle pseudo differential ADCs where we have something that looks like one side of differential input, but which is only suited for use with a slow moving reference. adi,adf4350 - Support use as a clock provider. iio-hmwon - Support reading of labels from IIO devices by their consumers and use this in the hwmon bridge. Cleanup and minor fixes ======================= Treewide - Use regmap_clear_bits() / regmap_set_bits() to simplify open coded equivalents. - Use devm_regulator_get_enable_read_voltage() to replace equivalent opencoded boilerplate. In some cases enabled complete conversion to devm handling and removal of explicit remove() callbacks. - Introduce dev_err_ptr_probe() and other variants and make use of of them in a couple of examples driver cleanups. Will find use in many more drivers soon. adi,ad7192 - Introduce local struct device *dev and use dev_err_probe() to give more readable code. adi,adi-axi-adc/dac - Improved consistency of messages using dev_err_probe() adi,adis - Split the trigger handling into cases that needed paging and those that don't resulting in more readable code. - Use cleanup.h to simplify error paths via scoped cleanup. - Add adis specific lock helpers and make use of them in a number of drivers. adi,ad7192 - Update maintainer (Alisa-Dariana Roman) adi,ad7606 - dt-binding cleanup. avago,apds9306 - Add a maintainer entry (Subhajit Ghosh) linear,ltc2309 - Fix a wrong endian type. st,stm32-dfsdm - Fix a missing port property in the dt-binding. st,sensors - Relax whoami match failure to a warning print rather than probe failure.

2024-06-30hwmon: (jc42) Use common device ID for TSE2004av compliant sensorsGuenter Roeck1-33/+10
TSE2004av standardizes the device ID of compliant temperature sensors to be 0x22xx, where xx is the device revision. Use a single define for all TSE2004av compliant temperature sensors, and relax the device id mask to match the upper 8 bit of the device id register. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2024-06-28hwmon: iio: Add labels from IIO channelsSean Anderson1-5/+40
Add labels from IIO channels to our channels. This allows userspace to display more meaningful names instead of "in0" or "temp5". Although lm-sensors gracefully handles errors when reading channel labels, the ABI says the label attribute > Should only be created if the driver has hints about what this voltage > channel is being used for, and user-space doesn't. Therefore, we test to see if the channel has a label before creating the attribute.

2024-06-19hwmon: (spd5118) Add support for Renesas/ITD SPD5118 hub controllersGuenter Roeck1-0/+56
The SPD5118 specification says, in its documentation of the page bits in the MR11 register: " This register only applies to non-volatile memory (1024) Bytes) access of SPD5 Hub device. For volatile memory access, this register must be programmed to '000'. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ " Renesas/ITD SPD5118 hub controllers take this literally and disable access to volatile memory if the page selected in MR11 is != 0. Since the BIOS or ROMMON will access the non-volatile memory and likely select a page != 0, this means that the driver will not instantiate since it can not identify the chip. Even if the driver instantiates, access to volatile registers is blocked after a nvram read operation which selects a page other than 0. To solve the problem, add initialization code to select page 0 during probe. Before doing that, use basic validation to ensure that this is really a SPD5118 device and not some random EEPROM.

2024-06-12hwmon: (ina2xx) Add device tree support to pass alert polarityAmna Waseem1-0/+32
The INA230 has an Alert pin which is asserted when the alert function selected in the Mask/Enable register exceeds the value programmed into the Alert Limit register. Assertion is based on the Alert Polarity Bit (APOL, bit 1 of the Mask/Enable register). It is default set to value 0 i.e Normal (active-low open collector). However, hardware can be designed in such a way that expects Alert pin to become active high if a user-defined threshold in Alert limit register has been exceeded. This patch adds a way to pass alert polarity value to the driver via device tree.
