2025-07-14iio: adc: ad4170-4: Add clock provider supportMarcelo Schmitt
The AD4170-4 chip can use an externally supplied clock at the XTAL2 pin, or an external crystal connected to the XTAL1 and XTAL2 pins. Alternatively, the AD4170-4 can provide its 16 MHz internal clock at the XTAL2 pin. In addition, the chip has a programmable clock divider that allows dividing the external or internal clock frequency, however, control for that is not provided in this patch. Extend the AD4170-4 driver so it effectively uses the provided external clock, if any, or supplies its own clock as a clock provider.

2025-07-14iio: adc: ad4170-4: Add support for buffered data captureMarcelo Schmitt
Extend the AD4170-4 driver to allow buffered data capture in continuous read mode. In continuous read mode, the chip skips the instruction phase and outputs just ADC sample data, enabling faster sample rates to be reached. The internal channel sequencer always starts sampling from channel 0 and channel 0 must be enabled if more than one channel is selected for data capture. The scan mask validation callback checks if the aforementioned condition is met.

2025-07-13iio: accel: adxl313: add AC coupled activity/inactivity eventsLothar Rubusch
Introduce AC-coupled activity and inactivity as MAG_ADAPTIVE events. This adds a new set of threshold and duration configuration options, ensures proper handling of event disabling, and extends the use of the link bit to support complementary event configurations. For example, either ACTIVITY or ACTIVITY_AC can be enabled, but only the most recently set configuration will remain active. Disabling ACTIVITY will have no effect if ACTIVITY_AC is currently enabled, as the event types must match (i.e., ACTIVITY_AC must be explicitly disabled). When either INACTIVITY or INACTIVITY_AC is enabled alongside an activity event, the link bit is set. With the link bit and auto-sleep enabled, activity and inactivity events represent changes in the sensor's power-saving state and are only triggered upon actual state transitions. Since AC coupling uses separate bits for activity and inactivity, each can be configured independently. For instance, ACTIVITY can be linked with INACTIVITY_AC. If one of the linked events is disabled, the link bit is cleared. In that case, the remaining event will no longer reflect a state transition but will instead trigger based on periodic inactivity or whenever the activity threshold is exceeded.

Set the signedness, number of storage bits, and endianness accordingly. - Parse the devicetree for an optional interrupt line and configure the interrupt mapping based on its presence. If no interrupt line is specified, keep the FIFO in bypass mode as currently implemented. - Set up the interrupt handler. Add register access to detect and evaluate interrupts. Implement functions to clear status registers and reset the FIFO. - Implement FIFO watermark configuration and handling.

2025-07-13iio: accel: adxl313: add function to enable measurementLothar Rubusch
Refactor the control of measurement and standby modes for the sensor. Instead of directly writing to the register, encapsulate this operation in a dedicated function that handles enabling and disabling measurement. This approach will reduce code duplication wherever sensor configuration changes are required. In subsequent patches, measurement mode will be set to standby as part of this process. Additionally, simplify the control mask to include only the measurement bit. The sleep bit governs a different behavior—putting the sensor into sleep mode, not just standby for configuration—and is currently unused. Therefore, there's no need to include both the sleep and measurement bits in the same mask.

MediaTek MT6363 is a PMIC found on MT8196/MT6991 board designs and communicates with the SoC over SPMI. This PMIC integrates an Auxiliary ADC (AUXADC) which has a grand total of 54 ADC channels: 49 PMIC-internal channels, 2 external NTC thermistor channels and 2 generic ADC channels (mapped to 7 PMIC ADC external inputs). To use a generic ADC channel it is necessary to enable one of the PMIC ADC inputs at a time and only then start the reading, so in this case it is possible to read only one external input for each generic ADC channel. Due to the lack of documentation, this implementation supports using only one generic ADC channel, hence supports reading only one external input at a time. Reviewed-by: Nícolas F. R. A.

2025-07-13iio: adc: ad_sigma_delta: use u8 instead of uint8_tDavid Lechner
Replace uint8_t with u8 in the ad_sigma_delta driver. Technically, uint8_t comes from the C standard library, while u8 is a Linux kernel type. Since we don't use the C standard library in the kernel, we should use the kernel types instead. There is also one instance where int64_t is replaced with s64.

Fix overallocating the size of the scan buffer by converting bits to bytes. The size is meant to be in bytes, so scanbits needs to be divided by 8.
