This patch series adds unit tests for the clk fixed rate basic type and the clk registration functions that use struct clk_parent_data. 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 almost all depend on each other. 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 Stephen Boyd (11): of: Add KUnit test to confirm DTB is loaded 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 | 22 + 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 | 215 ++++++++ drivers/clk/.kunitconfig | 3 + drivers/clk/Kconfig | 7 + drivers/clk/Makefile | 9 +- drivers/clk/clk-fixed-rate_test.c | 374 ++++++++++++++ drivers/clk/clk-fixed-rate_test.h | 8 + drivers/clk/clk_kunit.c | 224 +++++++++ drivers/clk/clk_parent_data_test.h | 10 + drivers/clk/clk_test.c | 459 +++++++++++++++++- drivers/clk/kunit_clk_fixed_rate_test.dtso | 19 + drivers/clk/kunit_clk_parent_data_test.dtso | 28 ++ drivers/of/.kunitconfig | 5 + drivers/of/Kconfig | 19 + drivers/of/Makefile | 4 + drivers/of/kunit_overlay_test.dtso | 9 + drivers/of/of_kunit.c | 125 +++++ drivers/of/of_test.c | 34 ++ drivers/of/overlay_test.c | 110 +++++ include/kunit/clk.h | 28 ++ include/kunit/of.h | 94 ++++ include/kunit/platform_device.h | 15 + 31 files changed, 2109 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/.kunitconfig create mode 100644 drivers/of/kunit_overlay_test.dtso create mode 100644 drivers/of/of_kunit.c create mode 100644 drivers/of/of_test.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 [1] https://lore.kernel.org/r/20230317053415.2254616-1-frowand.list@gmail.com base-commit: fe15c26ee26efa11741a7b632e9f23b01aca4cc6 prerequisite-patch-id: 33517b96dd0768ab9c265f5721629786354ee320 prerequisite-patch-id: 909221815eeca0a2b0cdd385c76f57e185fb9e33
