2024-06-13iio: temperature: mcp9600: add threshold events supportDimitri Fedrau1-14/+349
The device has four programmable temperature alert outputs which can be used to monitor hot or cold-junction temperatures and detect falling and rising temperatures. It supports up to 255 degree celsius programmable hysteresis. Each alert can be individually configured by setting following options in the associated alert configuration register: - monitor hot or cold junction temperature - monitor rising or falling temperature - set comparator or interrupt mode - set output polarity - enable alert This patch binds alert outputs to iio events: - alert1: hot junction, rising temperature - alert2: hot junction, falling temperature - alert3: cold junction, rising temperature - alert4: cold junction, falling temperature All outputs are set in comparator mode and polarity depends on interrupt configuration.

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

MLX90635 is an Infra Red contactless temperature sensor most suitable for consumer applications where measured object temperature is in range between -20 to 100 degrees Celsius. It has improved accuracy for measurements within temperature range of human body and can operate in ambient temperature range between -20 to 85 degrees Celsius. Driver provides simple power management possibility as it returns to lowest possible power mode (Step sleep mode) in which temperature measurements can still be performed, yet for continuous measuring it switches to Continuous power mode where measurements constantly change without triggering.

2023-09-23iio: temperature: hid-sensor: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
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() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Add support for MLX90615 Infra Red Thermometer, which seems to be the predecesor of MLX90614 . There are significant differences in the register layout compared to MLX90614, but the functionality of the device is virtually identical. The following differences have been identified: - RAM/EEPROM/SLEEP access opcodes are different - RAM/EEPROM registers are at different offsets - EEPROM emissivity and configuration registers are at different offsets - EEPROM configuration register bits are shuffled around - EEPROM emissivity settings are 14 bit on MLX90615 , 16 bit on MLX90614 - MLX90615 can only ever support one sensor, MLX90614 could support two - FIR filter is set to fixed settings on MLX90615 - IIR filter coefficients are different This patch fills in the MLX90615 specific description and quirk handling. The IIR filter coefficients were provided by Melexis as follows: 0b0000 - Forbidden value 0b0001 - 100% - settling time = refresh rate = 205ms (around 5Hz) 0b0010 - 50% - settling time = 2050ms (around 0.5Hz) 0b0011 - 33% - settling time = 36900ms (around 0.3Hz) 0b0100 - 25% - settling time = 5125ms (around 0.2Hz) 0b0101 - 20% - settling time = 6355ms (around 0.15Hz) 0b0110 - 17% - settling time = 7790ms (around 0.13Hz) 0b0111 - 14% - settling time = 9225ms (around 0.1Hz) Signed-off-by: Marek Vasut <[email protected]> Acked-by: Crt Mori <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jonathan Cameron <[email protected]>

2022-11-23iio: temperature: mlx90632 Add runtime powermanagement modesCrt Mori1-68/+309
The sensor can operate in lower power modes and even make measurements when in those lower powered modes. The decision was taken that if measurement is not requested within 2 seconds the sensor will remain in SLEEP_STEP power mode, where measurements are triggered on request with setting the start of measurement bit (SOB). In this mode the measurements are taking a bit longer because we need to start it and complete it. Currently, in continuous mode we read ready data and this mode is activated if sensor measurement is requested within 2 seconds. The suspend timeout is increased to 6 seconds (instead of 3 before), because that enables more measurements in lower power mode (SLEEP_STEP), with the lowest refresh rate (2 seconds).

2022-10-17iio: temperature: ltc2983: allocate iio channels onceCosmin Tanislav1-7/+6
Currently, every time the device wakes up from sleep, the iio_chan array is reallocated, leaking the previous one until the device is removed (basically never). Move the allocation to the probe function to avoid this.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König2-6/+2
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.
