iio: accel: adxl313: add missing error check in predisable

2026-04-11T12:29:47+00:00

commit 9d3fa23d5d55a137fd4396d3d4799102587a7f2b upstream. Check the return value of the FIFO bypass regmap_write() before proceeding to disable interrupts.

iio: accel: adxl380: fix FIFO watermark bit 8 always written as 0

2026-04-11T12:29:47+00:00

commit bd66aa1c8b8cabf459064a46d3430a5ec5138418 upstream. FIELD_PREP(BIT(0), fifo_samples & BIT(8)) produces either 0 or 256, and since FIELD_PREP masks to bit 0, 256 & 1 evaluates to 0. Use !! to convert the result to a proper 0-or-1 value.

iio: accel: fix ADXL355 temperature signature value

2026-04-11T12:29:47+00:00

commit 4f51e6c0baae80e52bd013092e82a55678be31fc upstream. Temperature was wrongly represented as 12-bit signed, confirmed by checking the datasheet. Even if the temperature is negative, the value in the register stays unsigned.

iio: accel: adxl380: Avoid reading more entries than present in FIFO

2026-03-04T12:21:23+00:00

[ Upstream commit c1b14015224cfcccd5356333763f2f4f401bd810 ] The interrupt handler reads FIFO entries in batches of N samples, where N is the number of scan elements that have been enabled. However, the sensor fills the FIFO one sample at a time, even when more than one channel is enabled. Therefore,the number of entries reported by the FIFO status registers may not be a multiple of N; if this number is not a multiple, the number of entries read from the FIFO may exceed the number of entries actually present. To fix the above issue, round down the number of FIFO entries read from the status registers so that it is always a multiple of N.

iio: accel: iis328dq: fix gain values

2026-01-11T12:00:08+00:00

The sensors IIS328DQ and H3LIS331DL share one configuration but H3LIS331DL has different gain parameters, configs therefore need to be split up. The gain parameters for the IIS328DQ are 0.98, 1.95 and 3.91, depending on the selected measurement range. See sensor manuals, chapter 2.1 "mechanical characteristics", parameter "Sensitivity".

iio: accel: adxl380: add support for ADXL318 and ADXL319

2025-11-15T17:11:35+00:00

The ADXL318 and ADXL319 are low noise density, low power, 3-axis accelerometers based on ADXL380 and ADXL382, respectively. The main difference between the new parts and the existing ones are the absence of interrupts and events like tap detection, activity/inactivity, and free-fall detection. Other differences in the new parts are fewer power modes, basically allowing only idle and measurement modes, and the removal of the 12-bit SAR ADC path for the 3-axis signals (known as lower signal chain), being excluisive for the temperature sensor in the ADXL318/319.
