clk: sprd: div: convert from divider_round_rate() to divider_determine_rate()

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

[ Upstream commit f78fb9422980ceeb340fa3a2e370ae8845798ec7 ] The divider_round_rate() 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.

clk: sprd: Composite driver support offset config

2023-10-24T03:24:02+00:00

The composite interface support the offset configuration, which is used to support mux and div in different registers. Because some sprd projects, the divider has different addresses from mux for one composite clk.

clk: Explicitly include correct DT includes

2023-07-19T20:13:16+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

clk: sprd: composite: Simplify determine_rate implementation

2023-06-14T19:43:26+00:00

The sprd_div_helper_round_rate() function calls divider_round_rate() which calls divider_round_rate_parent() which calls divider_determine_rate(). This call chain converts back and forth from the rate request structure to make a determine_rate clk_op fit with a round_rate clk_op. Simplify the code here by directly calling divider_determine_rate() instead. This fixes a smatch warning where an unsigned long is compared to less than zero, which is impossible. This makes sprd_div_helper_round_rate() unnecessary as well so simply remove it and fold it into the only caller left.
