clk: stm32: stm32-core: convert from divider_round_rate_parent() to divider_determine_rate()

2026-02-26T22:59:31+00:00

[ Upstream commit 2532795a6d6bb9791d713ffa9d9433f293b45b14 ] The divider_round_rate_parent() function is now deprecated, so let's migrate to divider_determine_rate() instead so that this deprecated API can be removed. Note that when the main function itself was migrated to use determine_rate, this was mistakenly converted to: req->rate = divider_round_rate(...) This is invalid in the case when an error occurs since it can set the rate to a negative value. Fixes: cd1cb38836c0 ("clk: stm32: stm32-core: convert from round_rate() to determine_rate()") Signed-off-by: Brian Masney Signed-off-by: Sasha Levin

clk: stm32: Do not enable by default during compile testing

2025-06-20T07:21:28+00:00

Enabling the compile test should not cause automatic enabling of all drivers. Restrict the default to ARCH also for individual driver, even though its choice is not visible without selecting parent Kconfig symbol, because otherwise selecting parent would select the child during compile testing.

clk: Switch back to struct platform_driver::remove()

2024-09-21T21:12:05+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all clk drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
