iio: add power and energy measurement modifiers

2025-09-13T12:47:19+00:00

Add new IIO modifiers to support power and energy measurement devices: Power modifiers: - IIO_MOD_ACTIVE: Real power consumed by the load - IIO_MOD_REACTIVE: Power that oscillates between source and load - IIO_MOD_APPARENT: Magnitude of complex power Signal quality modifiers: - IIO_MOD_RMS: Root Mean Square value Additionally adds: - IIO_CHAN_INFO_POWERFACTOR: Power factor channel info type for representing the ratio of active power to apparent power These modifiers enable proper representation of power measurement devices like energy meters and power analyzers.

iio: add IIO_ALTCURRENT channel type

2025-09-13T12:47:19+00:00

Add support for IIO_ALTCURRENT channel type to distinguish AC current measurements from DC current measurements. This follows the same pattern as IIO_VOLTAGE and IIO_ALTVOLTAGE. Reviewed-by: David Lechner Signed-off-by: Antoniu Miclaus Signed-off-by: Jonathan Cameron

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.

tools: iio: replace seekdir() in iio_generic_buffer

2024-01-23T22:06:56+00:00

Replace seekdir() with rewinddir() in order to fix a localized glibc bug. One of the glibc patches that stable Gentoo is using causes an improper directory stream positioning bug on 32bit arm. That in turn ends up as a floating point exception in iio_generic_buffer. The attached patch provides a fix by using an equivalent function which should not cause trouble for other distros and is easier to reason about in general as it obviously always goes back to to the start. https://sourceware.org/bugzilla/show_bug.cgi?id=31212 Signed-off-by: Petre Rodan Link: https://lore.kernel.org/r/20240108103224.3986-1-petre.rodan@subdimension.ro Signed-off-by: Jonathan Cameron

iio: add modifiers for A and B ultraviolet light

2023-12-04T13:57:24+00:00

Currently there are only two modifiers for ultraviolet light: a generic one for any ultraviolet light (IIO_MOD_LIGHT_UV) and one for deep ultraviolet (IIO_MOD_LIGHT_DUV), which is also referred as ultraviolet C (UV-C) band and covers short-wave ultraviolet. There are still no modifiers for the long-wave and medium-wave ultraviolet bands. These two bands are the main components used to obtain the UV index on the Earth's surface. Add modifiers for the ultraviolet A (UV-A) and ultraviolet B (UV-B) bands.
