drivers: base: test: Make property entry API test modular

2023-10-05T11:11:44+00:00

There is no reason why the KUnit Tests for the property entry API can only be built-in. Add support for building these tests as a loadable module, like is supported by most other tests.

software node: Switch property entry test to a new API

2023-01-17T18:04:26+00:00

Switch property entry test to use software_node_register_node_group() API. The current one is going to be removed soon.

device property: Remove some casts in property-entry-test

2021-06-23T22:37:21+00:00

With some of the stricter type checking in KUnit's EXPECT macros removed, several casts in property-entry-test are no longer required. Remove the unnecessary casts, making the conditions clearer.

software node: Introduce SOFTWARE_NODE_REFERENCE() helper macro

2021-04-05T11:18:22+00:00

This is useful to assign software node reference with arguments in a common way. Moreover, we have already couple of users that may be converted. And by the fact, one of them is moved right here to use the helper.

device property: Add test cases for fwnode_property_count_*() APIs

2021-03-23T14:04:06+00:00

Add test cases for fwnode_property_count_*() APIs. While at it, modify the arrays of integers to be size of non-power-of-2 for better test coverage and decreasing stack usage.

software node: add basic tests for property entries

2019-12-19T17:14:34+00:00

This adds tests for creating software nodes with properties supplied by PROPERTY_ENTRY_XXX() macros and fetching and validating data from said nodes/properties. We are using KUnit framework for the tests. Signed-off-by: Dmitry Torokhov Signed-off-by: Rafael J. Wysocki
