dm: test: Add tests for get/find uclass's device by name
This commit introduces simple tests for functions: - uclass_find_device_by_name() - uclass_get_device_by_name() Tests added by this commit: - Test: dm_test_uclass_devices_find_by_name: for uclass id: UCLASS_TEST_FDT * get uclass's devices by uclass_find_first/next_device() each as 'testdev', * for each returned device, call: uclass_find_device_by_name(), with previously returned device's name as an argument ('testdev->name'). * for the found device ('founddev') check if: * founddev != NULL * testdev == founddev * testdev->name == founddev->name (by strcmp) - Test: dm_test_uclass_devices_get_by_name: for uclass id: UCLASS_TEST_FDT * get uclass's devices by uclass_get_first/next_device() each as 'testdev', * for each returned device, call: uclass_get_device_by_name(), with previously returned device's name as an argument ('testdev->name'). * for the found device ('founddev') check if: * founddev != NULL * founddev is active * testdev == founddev * testdev->name == founddev->name (by strcmp) Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Simon Glass <sjg@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>
