2025-06-29iio: adc: ad7949: use spi_is_bpw_supported()David Lechner
Use spi_is_bpw_supported() instead of directly accessing spi->controller ->bits_per_word_mask. bits_per_word_mask may be 0, which implies that 8-bits-per-word is supported. spi_is_bpw_supported() takes this into account while spi_ctrl_mask == SPI_BPW_MASK(8) does not. Fixes: 0b2a740b424e ("iio: adc: ad7949: enable use with non 14/16-bit controllers") Closes: https://lore.kernel.org/linux-spi/c8b8a963-6cef-4c9b-bfef-dab2b7bd0b0f@sirena.org.uk/ Signed-off-by: David Lechner <dlechner@baylibre.com> Reviewed-by: Andy Shevchenko <andy@kernel.org> Link: https://patch.msgid.link/20250611-iio-adc-ad7949-use-spi_is_bpw_supported-v1-1-c4e15bfd326e@baylibre.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2025-06-29iio: accel: fxls8962af: Fix use after free in fxls8962af_fifo_flushSean Nyekjaer
fxls8962af_fifo_flush() uses indio_dev->active_scan_mask (with iio_for_each_active_channel()) without making sure the indio_dev stays in buffer mode. There is a race if indio_dev exits buffer mode in the middle of the interrupt that flushes the fifo. Fix this by calling synchronize_irq() to ensure that no interrupt is currently running when disabling buffer mode.

The AXP717 ADC channel maps is missing a sentinel entry at the end. This causes a KASAN warning. Add the missing sentinel entry.

2025-06-29iio: common: st_sensors: Fix use of uninitialize device structsMaud Spierings
Throughout the various probe functions &indio_dev->dev is used before it is initialized. This caused a kernel panic in st_sensors_power_enable() when the call to devm_regulator_bulk_get_enable() fails and then calls dev_err_probe() with the uninitialized device. This seems to only cause a panic with dev_err_probe(), dev_err(), dev_warn() and dev_info() don't seem to cause a panic, but are fixed as well. The issue is reported and traced here: [1] Link: https://lore.kernel.org/all/AM7P189MB100986A83D2F28AF3FFAF976E39EA@AM7P189MB1009.EURP189.PROD.OUTLOOK.COM/ [1] Cc: stable@vger.kernel.org Signed-off-by: Maud Spierings <maudspierings@gocontroll.com> Reviewed-by: Andy Shevchenko <andy@kernel.org> Link: https://...

2025-06-29iio: adc: adi-axi-adc: fix ad7606_bus_reg_read()David Lechner
Mask the value read before returning it. The value read over the parallel bus via the AXI ADC IP block contains both the address and the data, but callers expect val to only contain the data. axi_adc_raw_write() takes a u32 parameter, so addr was the wrong type. This wasn't causing any issues but is corrected anyway since we are touching the same line to add a new variable.

2025-06-26iio: amplifiers: ada4250: don't fail on bad chip IDDavid Lechner
Only print an information message instead of error message and failing to probe the device if the chip ID is not recognized. Experience shows that this can be fragile and some devices may not return the expected chip ID even though the driver is still able to work with them.

Refactor the apds9306_event_thresh_get() and apds9306_event_thresh_set() functions to use a helper function (apds9306_get_thresh_reg()) for obtaining the correct register based on the direction of the event.

2025-06-26iio: adc: ad7768-1: add filter type and oversampling ratio attributesJonathan Santos
Separate filter type and decimation rate from the sampling frequency attribute. The new filter type attribute enables sinc3, sinc3+rej60 and wideband filters, which were previously unavailable. Previously, combining decimation and MCLK divider in the sampling frequency obscured performance trade-offs. Lower MCLK divider settings increase power usage, while lower decimation rates reduce precision by decreasing averaging. By creating an oversampling attribute, which controls the decimation, users gain finer control over performance. The addition of those attributes allows a wider range of sampling frequencies and more access to the device features. Sampling frequency table is updated after every digital filter parameter change. Changes in the sampling frequency are not allowed anymore while in buffered mode.

2025-06-26iio: adc: ad7768-1: add support for Synchronization over SPIJonathan Santos
The synchronization method using GPIO requires the generated pulse to be truly synchronous with the base MCLK signal. When it is not possible to do that in hardware, the datasheet recommends using synchronization over SPI, where the generated pulse is already synchronous with MCLK. This requires the SYNC_OUT pin to be connected to the SYNC_IN pin. Use trigger-sources property to enable device synchronization over SPI and multi-device synchronization while replacing sync-in-gpios property.

2025-06-26iio: adc: ad7768-1: Add GPIO controller supportSergiu Cuciurean
The AD7768-1 has the ability to control other local hardware (such as gain stages),to power down other blocks in the signal chain, or read local status signals over the SPI interface. Add direct mode conditional locks in the GPIO callbacks to prevent register access when the device is in buffered mode. This change exports the AD7768-1's four GPIOs and makes them accessible at an upper layer.
