Arch maintainers, please ack/review patches. This is a resend of a series from Frank last year[1]. I worked in Rob's review comments to unconditionally call unflatten_device_tree() and fixup/audit calls to of_have_populated_dt() so that behavior doesn't change. I need this series so I can add DT based tests in the clk framework. Either I can merge it through the clk tree once everyone is happy, or Rob can merge it through the DT tree and provide some branch so I can base clk patches on it. Changes from Frank's series[1]: * Add a DTB loaded kunit test * Make of_have_populated_dt() return false if the DTB isn't from the bootloader * Architecture calls made unconditional so that a root node is always made Frank Rowand (2): of: Create of_root if no dtb provided by firmware of: unittest: treat missing of_root as error instead of fixing up Stephen Boyd (4): arm64: Unconditionally call unflatten_device_tree() um: Unconditionally call unflatten_device_tree() of: Always unflatten in unflatten_and_copy_device_tree() of: Add KUnit test to confirm DTB is loaded arch/arm64/kernel/setup.c | 3 +- arch/um/kernel/dtb.c | 14 +++--- drivers/of/.kunitconfig | 3 ++ drivers/of/Kconfig | 16 ++++++- drivers/of/Makefile | 4 +- drivers/of/empty_root.dts | 6 +++ drivers/of/fdt.c | 57 +++++++++++++++++------ drivers/of/of_test.c | 98 +++++++++++++++++++++++++++++++++++++++ drivers/of/platform.c | 3 -- drivers/of/unittest.c | 16 ++----- include/linux/of.h | 17 +++++-- 11 files changed, 191 insertions(+), 46 deletions(-) create mode 100644 drivers/of/.kunitconfig create mode 100644 drivers/of/empty_root.dts create mode 100644 drivers/of/of_test.c Cc: Anton Ivanov <anton.ivanov@cambridgegreys.com> Cc: Brendan Higgins <brendan.higgins@linux.dev> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: David Gow <davidgow@google.com> Cc: Frank Rowand <frowand.list@gmail.com> Cc: Johannes Berg <johannes@sipsolutions.net> Cc: Richard Weinberger <richard@nod.at> Cc: Rob Herring <robh+dt@kernel.org> Cc: Will Deacon <will@kernel.org> [1] https://lore.kernel.org/r/20230317053415.2254616-1-frowand.list@gmail.com base-commit: 0dd3ee31125508cd67f7e7172247f05b7fd1753a
