linux-toradex.git/drivers/of/of_test.c, branch v6.10-rc2 Linux kernel for Apalis and Colibri modules of: Add KUnit test to confirm DTB is loaded 2024-03-08T18:50:39+00:00 Stephen Boyd sboyd@kernel.org 2024-02-17T01:05:56+00:00 893ecc6d2d61381bc56991178cb3de697a948b78 Add a KUnit test that confirms a DTB has been loaded, i.e. there is a root node, and that the of_have_populated_dt() API works properly. We skip the test when CONFIG_OF_EARLY_FLATREE=n because in that case we know architecture code hasn't called unflatten_(and_copy_)?device_tree() which would populate some sort of root node.
