of/unittest: Add test that of_address_to_resource() fails on non-translatable address

2025-02-01T17:39:35+00:00

[ Upstream commit 44748065ed321041db6e18cdcaa8c2a9554768ac ] of_address_to_resource() on a non-translatable address should return an error. Additionally, this case also triggers a spurious WARN for missing #address-cells/#size-cells.

of: Fix double free in of_parse_phandle_with_args_map

2024-01-09T18:54:02+00:00

In of_parse_phandle_with_args_map() the inner loop that iterates through the map entries calls of_node_put(new) to free the reference acquired by the previous iteration of the inner loop. This assumes that the value of "new" is NULL on the first iteration of the inner loop. Make sure that this is true in all iterations of the outer loop by setting "new" to NULL after its value is assigned to "cur". Extend the unittest to detect the double free and add an additional test case that actually triggers this path.

of: unittest: Add tests for address translations

2023-10-27T21:37:42+00:00

Add tests to exercise address translations based on ranges properties. Tests added cover "default" (2cell) address translations, "default flags" (3cell) address translations and PCI address translations. They also cover PCI BAR translations introduced in commit 407d1a51921e ("PCI: Create device tree node for bridge").

of: unittest-data: Convert remaining overlay DTS files to sugar syntax

2023-08-24T01:04:17+00:00

Overlay syntactic sugar for generating target-path fragments is supported by the version of dtc supplied with the kernel since commit 50aafd60898a8b3e ("scripts/dtc: Update to upstream version v1.4.6-21-g84e414b0b5bc"). Hence convert the remaining unittest overlay devicetree source files to sugar syntax, improving readability. This completes the work started in commit db2f3762d609318e ("of: convert unittest overlay devicetree source to sugar syntax").
