2025-01-24of: address: Fix empty resource handling in __of_address_resource_bounds()Thomas Weißschuh
"resource->end" needs to always be equal to "resource->start + size - 1". The previous version of the function did not perform the "- 1" in case of an empty resource. Also make sure to allow an empty resource at address 0. Reported-by: Basharath Hussain Khaja <basharath@couthit.com> Closes: https://lore.kernel.org/lkml/20250108140414.13530-1-basharath@couthit.com/ Fixes: 1a52a094c2f0 ("of: address: Unify resource bounds overflow checking") Cc: stable@vger.kernel.org Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Link: https://lore.kernel.org/r/20250120-of-address-overflow-v1-1-dd68dbf47bce@linutronix.de Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
2025-01-24of/fdt: Restore possibility to use both ACPI and FDT from bootloaderDmytro Maluka
There are cases when the bootloader provides information to the kernel in both ACPI and DTB, not interchangeably. One such use case is virtual machines in Android. When running on x86, the Android Virtualization Framework (AVF) boots VMs with ACPI like it is usually done on x86 (i.e. the virtual LAPIC, IOAPIC, HPET, PCI MMCONFIG etc are described in ACPI) but also passes various AVF-specific boot parameters in DTB. This allows reusing the same implementations of various AVF components on both arm64 and x86. Commit 7b937cc243e5 ("of: Create of_root if no dtb provided by firmware") removed the possibility to do that, since among other things it introduced forcing emptying the bootloader-provided DTB if ACPI is enabled (probably assuming that if ACPI is available, a DTB can only be useful for applying overlays to it afterwards, for testing purposes). So restore this possibility. Instead of completely preventing using ACPI and DT together, rely on arch-specific setup code to prevent using both to set up the same things (see various acpi_disabled checks under arch/).

2024-12-16of: Fix of_find_node_opts_by_path() handling of alias+path+optionsZijun Hu
of_find_node_opts_by_path() fails to find OF device node when its @path parameter have pattern below: "alias-name/node-name-1/.../node-name-N:options". The reason is that alias name length calculated by the API is wrong, as explained by example below: "testcase-alias/phandle-tests/consumer-a:testaliasoption". ^ ^ ^ 0 14 39 The right length of alias 'testcase-alias' is 14, but the result worked out by the API is 39 which is obvious wrong. Fix by using index of either '/' or ':' as the length who comes earlier.
