Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

iio: hid-sensor-rotation: Fix stale or zero output when reading raw values

2026-06-29T22:24:46+00:00

When reading the raw quaternion attribute (in_rot_quaternion_raw), the driver currently returns either all zeros (if the sensor was never enabled) or stale data (if the sensor was previously enabled) because it reads from the internal buffer without explicitly requesting a new sample from the sensor. To fix this, power up the sensor, call sensor_hub_input_attr_read_values() to issue a synchronous GET_REPORT and receive the full quaternion data directly into a local buffer, then decode the four components.

iio: orientation: hid-sensor-rotation: use ext_scan_type

2026-04-27T08:58:16+00:00

Make use of ext_scan_type to handle the dynamic realbits size of the quaternion data. This lets us implement it using static data rather than having to duplicate the channel info for each driver instance.

iio: orientation: hid-sensor-rotation: add timestamp hack to not break userspace

2026-03-14T12:15:58+00:00

Add a hack to push two timestamps in the hid-sensor-rotation scan data to avoid breaking userspace applications that depend on the timestamp being at the incorrect location in the scan data due to unintentional misalignment in older kernels. When this driver was written, the timestamp was in the correct location because of the way iio_compute_scan_bytes() was implemented at the time. (Samples were 24 bytes each.) Then commit 883f61653069 ("iio: buffer: align the size of scan bytes to size of the largest element") changed the computed scan_bytes to be a different size (32 bytes), which caused iio_push_to_buffers_with_timestamp() to place the timestamp at an incorrect offset. There have been long periods of time (6 years each) where the timestamp was in either location, so to not break either case, we open-code the timestamps to be pushed to both locations in the scan data.

iio: orientation: hid-sensor-rotation: fix quaternion alignment

2026-03-02T20:53:16+00:00

Restore the alignment of sampled_vals to 16 bytes by using IIO_DECLARE_QUATERNION(). This field contains a quaternion value which has scan_type.repeat = 4 and storagebits = 32. So the alignment must be 16 bytes to match the assumptions of iio_storage_bytes_for_si() and also to not break userspace.

iio: normalize array sentinel style

2025-04-22T18:10:04+00:00

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.

iio: Switch back to struct platform_driver::remove()

2024-10-10T18:31:50+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/iio/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.
