2023-12-17iio: adc: ad7091r: Pass iio_dev to event handlerMarcelo Schmitt1-3/+3
Previous version of ad7091r event handler received the ADC state pointer and retrieved the iio device from driver data field with dev_get_drvdata(). However, no driver data have ever been set, which led to null pointer dereference when running the event handler. Pass the iio device to the event handler and retrieve the ADC state struct from it so we avoid the null pointer dereference and save the driver from filling the driver data field.

A simple driver for the TVOC (Total Volatile Organic Compounds) sensor from Aosong: AGS02MA Steps in reading the VOC sensor value over i2c: 1. Read 5 bytes from the register `AGS02MA_TVOC_READ_REG` [0x00] 2. The first 4 bytes are taken as the big endian sensor data with final byte being the CRC 3. The CRC is verified and the value is returned over an `IIO_CHAN_INFO_RAW` channel as percents Tested on Raspberry Pi Zero 2W Datasheet: https://asairsensors.com/wp-content/uploads/2021/09/AGS02MA.pdf Signed-off-by: Anshul Dalal <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jonathan Cameron <[email protected]>

The IIO_CHAN_INFO_PEAK info element is used for maximum values and currently there is no equivalent for minimum values. Instead of overloading the existing peak info element, a new info element can be added. In principle there is no need to add a _TROUGH_SCALE element as the scale will be the same as the one required for INFO_PEAK, which in turn is sometimes omitted if a single scale for peaks and raw values is required.

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.

2023-12-10iio: adc: ad9467: fix scale settingNuno Sa3-59/+66
When reading in_voltage_scale we can get something like: root@analog:/sys/bus/iio/devices/iio:device2# cat in_voltage_scale 0.038146 However, when reading the available options: root@analog:/sys/bus/iio/devices/iio:device2# cat in_voltage_scale_available 2000.000000 2100.000006 2200.000007 2300.000008 2400.000009 2500.000010 which does not make sense. Moreover, when trying to set a new scale we get an error because there's no call to __ad9467_get_scale() to give us values as given when reading in_voltage_scale. Fix it by computing the available scales during probe and properly pass the list when .read_available() is called. While at it, change to use .read_available() from iio_info. Also note that to properly fix this, adi-axi-adc.c has to be changed accordingly.

2023-12-10iio: adc: ad9467: fix reset gpio handlingNuno Sa1-13/+18
The reset gpio was being handled with inverted polarity. This means that as far as gpiolib is concerned we were actually leaving the pin asserted (in theory, this would mean reset). However, inverting the polarity in devicetree made things work. Fix it by doing it the proper way and how gpiolib expects it to be done. While at it, moved the handling to it's own function and dropped 'reset_gpio' from the 'struct ad9467_state' as we only need it during probe. On top of that, refactored things so that we now request the gpio asserted (i.e in reset) and then de-assert it. Also note that we now use gpiod_set_value_cansleep() instead of gpiod_direction_output() as we already request the pin as output.

2023-11-26iio: amplifiers: hmc425a: add support for ADRF5740 AttenuatorAna-Maria Cusco1-0/+23
This adds support for the Analog Devices ADRF5740 2 dB LSB, 4-Bit, Silicon Digital Attenuator, 10 MHz to 60 GHz. The default (maximum) gain is also set at probe time, with GPIO lines driven high to achieve maximum gain, in contrast to other devices where GPIOs need to be driven low.

2023-11-25MAINTAINERS: improve section MICROCHIP MCP3564 ADC DRIVERLukas Bulwahn1-5/+6
Commit 33ec3e5fc1ea ("iio: adc: adding support for MCP3564 ADC") adds a new iio driver and corresponding MAINTAINERS section. It however uses spaces instead of a single tab for all the entries in that MAINTAINERS section. Although, the get_maintainer.pl script handles spaces instead of tabs silently, the MAINTAINERS will quickly get into a messy state with different indentations throughout the file. So, the checkpatch.pl script complains when spaces instead of a single tab are used. Fix this recently added section using tabs instead of spaces. Further, add the driver's ABI documentation file to this section as well.
