Subject: [PATCH v4 00/10] clk: Add kunit tests for fixed rate and parent data
Date: Mon, 22 Apr 2024 16:23:53 -0700 [thread overview]
Message-ID: <20240422232404.213174-1-sboyd@kernel.org> (raw)
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 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
