iio: test: iio-test-format: add test case for decimal format

2026-06-29T23:15:52+00:00

Add iio_test_iio_format_value_decimal_64() kunit test case for decimal value formatting, exploring different scales types. Also, the same iio_val_s64_decompose() helper used to populate local array is used in iio_test_iio_format_value_integer_64().

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.

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

iio: test: gts: test available times and gains sorting

2024-05-27T08:48:56+00:00

The iio_gts helpers build available times and scales tables based on the times and gains arrays given from the driver. The driver should be able to list all valid register values so that conversion from register valu to correct gain/time works for all supported register values. It might be more convenient for drivers to list these times and gains in the order where they're listed in the data-sheet than ascending order. However, for user who requests the supported scales / times it is more convenient to get the results in asscending order. Also, listing duplicated values is not meaning for the user. Hence the GTS heler should do sorting and deduplication of the scales and times when it builds the tables listing the available times/scales. Note, currently duplicated gain values aren't handled by GTS-helpers. Unsort the gain and time arrays in the test code, and add duplicates to time array in order to test the sorting and deduplicating works.
