Merge tag 'clk-misc-for-v7.3' of ssh://github.com/masneyb/linux into clk-pile

2026-08-17T16:27:10+00:00

Pull clk patches picked up by Brian Masney: Here's various improvements and fixes for the clk subsystem that was posted prior to the opening of the last merge window. - Add spread spectrum clock (SSC) support to the clk framework, including a new assigned-clock-sscs devicetree property and clk_hw_set_spread_spectrum() API with KUnit tests (Peng Fan) - Add SCMI clock OEM extensions for the i.MX95 clock driver and introduce a common SCMI clock header (Peng Fan) - Add clock, reset, and devicetree bindings for the ESWIN EIC7700 HSP clock and reset generator (Xuyang Dong) - Add clk_determine_rate_noop() helper for clock drivers that can do any rate, and convert existing open-coded implementations across hisilicon, imx, qcom, renesas, rp1, samsung, scpi, sprd, mediatek phy, and mediatek pmdomain drivers (Brian Masney) - Add kernel-doc documentation for struct clk_core and the core clock flags, and wire up clk identifiers into the documentation build (Brian Masney) - Fix clk_divider_bestdiv() returning the minimum rate instead of the maximum rate for large rate requests, with KUnit tests (Lad Prabhakar) - Fix Nuvoton MA35D1 PLL frequency calculation including ignored div_u64 return values, incorrect PLL_CTL1_FRAC bit field width, and broken determine_rate logic (Joey Lu) - Support unique clock names for multi-socket Tegra platforms (Jon Hunter) - Allow COMPILE_TEST builds for HiSilicon clock drivers (Rosen Penev) - Various fixes and cleanups from Akari Tsuyukusa, Alexander A.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

clk: sprd: use clk_determine_rate_noop()

Drop the driver-specific empty determine_rate() function and use the new shared clk_determine_rate_noop() helper. Signed-off-by: Brian Masney

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

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

2026-01-22T15:48:26+00:00

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: sc9860: Simplify with of_device_get_match_data()

2025-11-11T01:02:12+00:00

Driver's probe function matches against driver's of_device_id table, where each entry has non-NULL match data, so of_match_node() can be simplified with of_device_get_match_data().

clk: sprd: pll: convert from round_rate() to determine_rate()

The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch on the cover letter of this series. Reviewed-by: Chunyan Zhang Signed-off-by: Brian Masney
