Subject: [PATCH v3 00/11] clk: Add kunit tests for fixed rate and parent data
Date:   Mon, 27 Mar 2023 15:21:48 -0700

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
