Subject: [PATCH v2 0/7] of: populate of_root node if bootloader doesn't
Date: Mon, 29 Jan 2024 16:44:59 -0800 [thread overview]
Message-ID: <20240130004508.1700335-1-sboyd@kernel.org> (raw)
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
Changes from v1 (https://lore.kernel.org/r/20240112200750.4062441-1-sboyd@kernel.org):
* x86 patch included
* arm64 knocks out initial dtb if acpi is in use
* keep Kconfig hidden but def_bool enabled otherwise
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 (5):
arm64: Unconditionally call unflatten_device_tree()
um: Unconditionally call unflatten_device_tree()
x86/of: Unconditionally call unflatten_and_copy_device_tree()
of: Always unflatten in unflatten_and_copy_device_tree()
of: Add KUnit test to confirm DTB is loaded
