Relying on CONFIG_PM_SLEEP to set PM ops is not necessary since core will handle everything internally. One have to only make sure that functions that can go unused are marked with __maybe_unused. Signed-off-by:

The adxl372 is designed to communicate in either SPI or I2C protocol. It autodetects the format being used, requiring no configuration control to select the format. Signed-off-by:

Stefan Popa authored
This patch restructures the existing adxl372 driver by adding a module for SPI and a header file, while the baseline module deals with the chip-logic. This is a necessary step, as this driver should support in the future a similar device which differs only in the type of interface used (I2C instead of SPI). Signed-off-by:

The documentation of Qualcomm's SPMI PMIC voltage ADC claims that the 'reg' property consists of two values, the SPMI address and the length of the controller's registers. However the SPMI bus to which it is added specifies "#size-cells = <0>;". Remove the controller register length from the documentation of the field and the example. Signed-off-by:

The ad5758 has a hardware reset active low input pin. This patch adds a devicetree entry for a reset GPIO and a new ad5758_reset() function. During initialization, it is checked if the reset property is specified and the the GPIO is being asserted, therefore the device will become active. When the reset function is called, if the gpio_reset var is set, then the GPIO will be toggled, otherwise a software reset is performed. Signed-off-by:

The headset device will use channel 20 of ADC controller to detect events, but it needs the raw ADC data to do conversion according to its own formula. Thus we should configure the channel mask separately and configure channel 20 as IIO_CHAN_INFO_RAW, as well as adding raw data read support. Signed-off-by:

This patch adds the option for the user to select the filter bandwidth. The user can also read the available bandwidths which are always adjusted to be at most half of the sampling frequency. Furthermore, the currently selected bandwidth can be read via the read_raw function, while the write_raw sets a new bandwidth value. Signed-off-by:

This patch adds the option for the user to select the sampling frequency. Also, the user can read the available frequencies and read the currently set frequency via the read_raw function. The frequency can be set via the write_raw function. When the frequency is set, the bandwidth is also checked and ensured that it is constrained to at most half of the sampling frequency. Also, the activity and inactivity timers have to be updated because they depend on the selected ODR. Signed-off-by:

Drop call to of_match_device, which is subsumed by the subsequent call to of_device_get_match_data. The code becomes simpler, and a temporary variable can be dropped.

val2 is responsible for the floating part of the number to be written to the device. We don't need the floating part while writing the oversampling ratio for BME680 since the available oversampling ratios are pure natural numbers. So, add a sanity check to make sure val2 is 0. Signed-off-by:

Fixes ef89f4b9 ("iio: adxl345: Add support for the ADXL375"). This was found via static checker. After looking into the code a bit, it's unlikely that there will be a NULL dereference if the `id` object in that specific code path. However, it's safe to add a NULL (paranoid) check just to make sure and remove any uncertainties. Reported-by:
