To get there, we add support for loading device tree overlays onto the live DTB along with probing platform drivers to bind to device nodes in the overlays. With this series, we're able to exercise some of the code in the common clk framework that uses devicetree lookups to find parents and the fixed rate clk code that scans device tree directly and creates clks. Please review. I Cced everyone to all the patches so they get the full context. I'm hoping I can take the whole pile through the clk tree as they all build upon each other. Or the DT part can be merged through the DT tree to reduce the dependencies. Changes from v3 (https://lore.kernel.org/r/20230327222159.3509818-1-sboyd@kernel.org): * No longer depend on Frank's series[1] because it was merged upstream[2] * Use kunit_add_action_or_reset() to shorten code * Skip tests properly when CONFIG_OF_OVERLAY isn't set Changes from v2 (https://lore.kernel.org/r/20230315183729.2376178-1-sboyd@kernel.org): * Overlays don't depend on __symbols__ node * Depend on Frank's always create root node if CONFIG_OF series[1] * Added kernel-doc to KUnit API doc * Fixed some kernel-doc on functions * More test cases for fixed rate clk Changes from v1 (https://lore.kernel.org/r/20230302013822.1808711-1-sboyd@kernel.org): * Don't depend on UML, use unittest data approach to attach nodes * Introduce overlay loading API for KUnit * Move platform_device KUnit code to drivers/base/test * Use #define macros for constants shared between unit tests and overlays * Settle on "test" as a vendor prefix * Make KUnit wrappers have "_kunit" postfix [1] https://lore.kernel.org/r/20230317053415.2254616-1-frowand.list@gmail.com [2] https://lore.kernel.org/r/20240308195737.GA1174908-robh@kernel.org Stephen Boyd (10): of: Add test managed wrappers for of_overlay_apply()/of_node_put() dt-bindings: vendor-prefixes: Add "test" vendor for KUnit and friends dt-bindings: test: Add KUnit empty node binding of: Add a KUnit test for overlays and test managed APIs platform: Add test managed platform_device/driver APIs dt-bindings: kunit: Add fixed rate clk consumer test clk: Add test managed clk provider/consumer APIs clk: Add KUnit tests for clk fixed rate basic type dt-bindings: clk: Add KUnit clk_parent_data test clk: Add KUnit tests for clks registered with struct clk_parent_data Documentation/dev-tools/kunit/api/clk.rst | 10 + Documentation/dev-tools/kunit/api/index.rst | 21 + Documentation/dev-tools/kunit/api/of.rst | 13 + .../dev-tools/kunit/api/platformdevice.rst | 10 + .../bindings/clock/test,clk-parent-data.yaml | 47 ++ .../bindings/test/test,clk-fixed-rate.yaml | 35 ++ .../devicetree/bindings/test/test,empty.yaml | 30 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + drivers/base/test/Makefile | 3 + drivers/base/test/platform_kunit-test.c | 140 ++++++ drivers/base/test/platform_kunit.c | 174 +++++++ drivers/clk/.kunitconfig | 2 + drivers/clk/Kconfig | 9 + drivers/clk/Makefile | 9 +- drivers/clk/clk-fixed-rate_test.c | 377 +++++++++++++++ drivers/clk/clk-fixed-rate_test.h | 8 + drivers/clk/clk_kunit.c | 198 ++++++++ drivers/clk/clk_parent_data_test.h | 10 + drivers/clk/clk_test.c | 451 +++++++++++++++++- drivers/clk/kunit_clk_fixed_rate_test.dtso | 19 + drivers/clk/kunit_clk_parent_data_test.dtso | 28 ++ drivers/of/.kunitconfig | 1 + drivers/of/Kconfig | 10 + drivers/of/Makefile | 2 + drivers/of/kunit_overlay_test.dtso | 9 + drivers/of/of_kunit.c | 99 ++++ drivers/of/overlay_test.c | 115 +++++ include/kunit/clk.h | 28 ++ include/kunit/of.h | 94 ++++ include/kunit/platform_device.h | 15 + 30 files changed, 1967 insertions(+), 2 deletions(-) create mode 100644 Documentation/dev-tools/kunit/api/clk.rst create mode 100644 Documentation/dev-tools/kunit/api/of.rst create mode 100644 Documentation/dev-tools/kunit/api/platformdevice.rst create mode 100644 Documentation/devicetree/bindings/clock/test,clk-parent-data.yaml create mode 100644 Documentation/devicetree/bindings/test/test,clk-fixed-rate.yaml create mode 100644 Documentation/devicetree/bindings/test/test,empty.yaml create mode 100644 drivers/base/test/platform_kunit-test.c create mode 100644 drivers/base/test/platform_kunit.c create mode 100644 drivers/clk/clk-fixed-rate_test.c create mode 100644 drivers/clk/clk-fixed-rate_test.h create mode 100644 drivers/clk/clk_kunit.c create mode 100644 drivers/clk/clk_parent_data_test.h create mode 100644 drivers/clk/kunit_clk_fixed_rate_test.dtso create mode 100644 drivers/clk/kunit_clk_parent_data_test.dtso create mode 100644 drivers/of/kunit_overlay_test.dtso create mode 100644 drivers/of/of_kunit.c create mode 100644 drivers/of/overlay_test.c create mode 100644 include/kunit/clk.h create mode 100644 include/kunit/of.h create mode 100644 include/kunit/platform_device.h base-commit: 4cece764965020c22cff7665b18a012006359095 -- https://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git/ https://git.kernel.org/pub/scm/linux/kernel/git/sboyd/spmi.git
