From: Peng Fan <[email protected]> Add KUnit test coverage for the assigned-clock-sscs DT property that configures spread spectrum on clocks before they are used. Extend the existing test infrastructure to support spread spectrum: - Add struct clk_spread_spectrum field to clk_dummy_context and a clk_dummy_set_spread_spectrum callback - Wire set_spread_spectrum into all dummy clock ops - Extend clk_assigned_rates_register_clk and test parameter struct to propagate initial SSCS values Add a new separate test suite clk_assigned_sscs with three categories: 1. clk_assigned_sscs_assigns_one — verifies that a single assigned-clock-sscs entry correctly configures spread spectrum on one clock, testing both provider and consumer paths 2. clk_assigned_sscs_assigns_multiple — verifies that multiple assigned-clock-sscs entries configure spread spectrum on two clocks, testing both provider and consumer paths 3. clk_assigned_sscs_skips — verifies that malformed DT properties are correctly skipped without error: missing assigned-clocks, zero-valued SSCS, and null phandles, tested for both provider and consumer scenarios New DT overlays are added for all test scenarios: - kunit_clk_assigned_sscs_one{,consumer} — single valid entry - kunit_clk_assigned_sscs_multiple{,consumer} — two valid entries - kunit_clk_assigned_sscs_without{,consumer} — missing assigned-clocks - kunit_clk_assigned_sscs_zero{,consumer} — all-zero SSCS values - kunit_clk_assigned_sscs_null{,consumer} — null phandle Co-developed-by: Brian Masney <[email protected]> Signed-off-by: Brian Masney <[email protected]> Signed-off-by: Peng Fan <[email protected]> --- drivers/clk/Makefile | 10 + drivers/clk/clk_test.c | 203 ++++++++++++++++++++- drivers/clk/kunit_clk_assigned_rates.h | 10 + .../clk/kunit_clk_assigned_rates_u64_multiple.dtso | 6 + ...t_clk_assigned_rates_u64_multiple_consumer.dtso | 6 + drivers/clk/kunit_clk_assigned_rates_u64_one.dtso | 3 + .../kunit_clk_assigned_rates_u64_one_consumer.dtso | 3 + drivers/clk/kunit_clk_assigned_sscs_multiple.dtso | 20 ++ .../kunit_clk_assigned_sscs_multiple_consumer.dtso | 24 +++ drivers/clk/kunit_clk_assigned_sscs_null.dtso | 16 ++ .../clk/kunit_clk_assigned_sscs_null_consumer.dtso | 20 ++ drivers/clk/kunit_clk_assigned_sscs_one.dtso | 16 ++ .../clk/kunit_clk_assigned_sscs_one_consumer.dtso | 20 ++ drivers/clk/kunit_clk_assigned_sscs_without.dtso | 15 ++ .../kunit_clk_assigned_sscs_without_consumer.dtso | 19 ++ drivers/clk/kunit_clk_assigned_sscs_zero.dtso | 12 ++ .../clk/kunit_clk_assigned_sscs_zero_consumer.dtso | 16 ++ 17 files changed, 416 insertions(+), 3 deletions(-) diff --git a/drivers/clk/Makefile b/drivers/clk/Makefile index 6899e32e14aa6..3a73b81c2ec08 100644 --- a/drivers/clk/Makefile +++ b/drivers/clk/Makefile @@ -18,6 +18,16 @@ clk-test-y := clk_test.o \ kunit_clk_assigned_rates_without_consumer.dtbo.o \ kunit_clk_assigned_rates_zero.dtbo.o \ kunit_clk_assigned_rates_zero_consumer.dtbo.o \ + kunit_clk_assigned_sscs_one.dtbo.o \ + kunit_clk_assigned_sscs_one_consumer.dtbo.o \ + kunit_clk_assigned_sscs_multiple.dtbo.o \ + kunit_clk_assigned_sscs_multiple_consumer.dtbo.o \ + kunit_clk_assigned_sscs_null.dtbo.o \ + kunit_clk_assigned_sscs_null_consumer.dtbo.o \ + kunit_clk_assigned_sscs_without.dtbo.o \ + kunit_clk_assigned_sscs_without_consumer.dtbo.o \ + kunit_clk_assigned_sscs_zero.dtbo.o \ + kunit_clk_assigned_sscs_zero_consumer.dtbo.o \ kunit_clk_hw_get_dev_of_node.dtbo.o \ kunit_clk_parent_data_test.dtbo.o obj-$(CONFIG_COMMON_CLK) += clk-divider.o diff --git a/drivers/clk/clk_test.c b/drivers/clk/clk_test.c index b1961daac5e22..824adc95e0b2f 100644 --- a/drivers/clk/clk_test.c +++ b/drivers/clk/clk_test.c @@ -28,6 +28,7 @@ static const struct clk_ops empty_clk_ops = { };
