iio: proximity: isl29501: fix buffered read on big-endian systems

2025-08-11T20:35:01Z

Fix passing a u32 value as a u16 buffer scan item. This works on little- endian systems, but not on big-endian systems. A new local variable is introduced for getting the register value and the array is changed to a struct to make the data layout more explicit rather than just changing the type and having to recalculate the proper length needed for the timestamp. Fixes: 1c28799257bc ("iio: light: isl29501: Add support for the ISL29501 ToF sensor.")

iio: Add driver for Nicera D3-323-AA PIR sensor

2025-07-14T18:20:55Z

Nicera D3-323-AA is a PIR sensor for human detection. It has support for raw data measurements and detection notification. The communication protocol is custom made and therefore needs to be GPIO bit banged. The device has two main settings that can be configured: a threshold value for detection and a band-pass filter. The configurable parameters for the band-pass filter are the high-pass and low-pass cutoff frequencies and its peak gain. Map these settings to the corresponding parameters in the `iio` framework. Raw data measurements can be obtained from the device. However, since we rely on bit banging, it will be rather cumbersome with buffer support. The main reason being that the data protocol has strict timing requirements (it's serial like UART), and it's mainly used during debugging since in real-world applications only the event notification is of importance. Therefore, only add support for events (for now).

Add const qualifier to struct vcnl3020_property vcnl3020_led_current_property. This is read-only data so it can be made const. Signed-off-by: David Lechner Link: https://patch.msgid.link/20250628-iio-const-data-25-v1-2-5d99cf17790e@baylibre.com Signed-off-by: Jonathan Cameron

iio: Remove single use of macro definition for IRQ name

2025-06-09T06:45:36Z

There is really no reason for having the IRQ name as a macro definition if it is only used once (often in functions requesting the IRQ). It is also more readable this way. Remove these macro definitions and instead use the string literal directly.

iio: irsd200: Remove print of error code from dev_err_probe

2025-06-09T06:45:34Z

Since `dev_err_probe()` already prints the error code, there is no need to additionally print it in the error message. Therefore, just remove them.

iio: proximity: Use iio_push_to_buffers_with_ts() to provide length for runtime checks.

2025-05-21T13:20:26Z

This new function allows us to perform debug checks in the helper to ensure that the overrun does not occur. Use it in all the simple cases where either a static buffer or a structure is used in the drivers.

iio: proximity: irsd200: Use a struct for scan and iio_push_to_buffers_with_ts()

2025-05-21T13:20:26Z

The driver previously used an array of two s64, then type cast the pointer to write an s16 to the start. The code is made more readable using a structure. At the same time switch to the new iio_push_to_buffers_with_ts() helper to enable runtime checking of the size of the source buffer. Note that this approach uses a structure with holes, so use memset() to ensure those do not contain old kernel data as this data is passed to userspace.

iio: normalize array sentinel style

2025-04-22T18:10:04Z

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace the array sentinel in all IIO drivers to the same style. For some time, we've been trying to consistently use `{ }` (no trailing comma, no comment, one space between braces) for array sentinels in the IIO subsystem. Still nearly 50% of existing code uses a different style. To save reviewers from having to request this trivial change as frequently, let's normalize the style in all existing IIO drivers. At least when code is copy/pasted to new drivers, the style will be consistent.
