Date: Mon, 29 Jun 2026 18:34:49 -0400 [thread overview]
Message-ID: <akLzCVzbMbUsgDda@redhat.com> (raw)
Hi Stephen,
Here's various improvements and fixes that weren't picked up during the
last merge window that I feel are ready. Let me know if you'd like me to
drop anything and I can send you a v2. Details from the 19 contributors are
below in the signed tag.
The following changes since commit dc59e4fea9d83f03bad6bddf3fa2e52491777482:
Linux 7.2-rc1 (2026-06-28 12:01:31 -0700)
are available in the Git repository at:

pmdomain: mediatek: mtk-mfg: use clk_determine_rate_noop() (2026-06-29 17:53:17 -0400)
----------------------------------------------------------------
clk: various improvements and fixes
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. Klimov,
Brian Masney, David Carlier, David Laight, Min zhang, Myeonghun Pak,
Pavel Löbl, Randy Dunlap, Rob Herring, Rosen Penev, Uwe Kleine-König,
William Theesfeld, Xuyang Dong, and Yu-Chun Lin
