2025-07-06iio: imu: bmi270: add channel for step counterGustavo Silva1-0/+138
Add a channel for enabling/disabling the step counter, reading the number of steps and resetting the counter.

2025-07-01include: linux: move adi-axi-common.h out of fpgaNuno Sá2-3/+2
The adi-axi-common.h header has some common defines used in various ADI IPs. However they are not specific for any fpga manager so it's questionable for the header to live under include/linux/fpga. Hence let's just move one directory up and update all users.

2025-06-29iio: dac: ad3530r: Fix incorrect masking for channels 4-7 in powerdown modeKim Seer Paller1-1/+3
In the current implementation of ad3530r_set_dac_powerdown() function, the macro AD3530R_OP_MODE_CHAN_MSK(chan->channel) is used to generate the bitmask for the operating mode of a specific channel. However, this macro does not account for channels 4-7, which map to the second register AD3530R_OUTPUT_OPERATING_MODE_1 for the 8 channeled device. As a result, the bitmask is incorrectly calculated for these channels, leading to improper configuration of the powerdown mode. Resolve this issue by adjusting the channel index for channels 4-7 by subtracting 4 before applying the macro. This ensures that the correct bitmask is generated for the second register.

Change the data type of the "adi,gain-milli" property from u32 to u16.

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.

2025-06-29iio: accel: fxls8962af: Fix use after free in fxls8962af_fifo_flushSean Nyekjaer1-0/+2
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.

2025-06-29iio: common: st_sensors: Fix use of uninitialize device structsMaud Spierings3-35/+31
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://...

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.

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.

2025-06-26iio: adc: ad7768-1: add filter type and oversampling ratio attributesJonathan Santos1-95/+319
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.
