Is there a pending fix? Also, why is GS101 I don't see any of these warnings. Neither local (W=1), nor on my CI, nor reported by LKP (which reported build successes for this branch). How can I reproduce it? > describing clk parents with strings instead of using clk_parent_data? GS101 uses existing Samsuung clock framework, so that's how it is done there.

I ran this command make W=1 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- drivers/clk/samsung/clk-gs101.o and I see the warnings.

There is nothing odd here, comparing to other Samsung clocks. Ok.

Weird! I use gcc-12.2 if that helps. I've been meaning to upgrade but I also don't see much urgency. I'll wait for the next PR.

The following changes since commit 4cece764965020c22cff7665b18a012006359095: Linux 6.9-rc1 (2024-03-24 14:10:05 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git tags/samsung-clk-6.10 for you to fetch changes up to 6b32d7474e9b833dc7fadc1b4d4f08af9bd87fde: clk: samsung: gs101: mark some apm UASC and XIU clocks critical (2024-05-03 10:34:34 +0200) ---------------------------------------------------------------- Samsung SoC clock drivers changes for 6.10 1. Allow choice of manual or firmware-driven control over PLLs, needed to fully implement CPU clock controllers on Exynos850. 2. Correct PLL clock IDs on ExynosAutov9. 3. Google GS101: - Propagate certain clock rates to allow setting proper SPI clock rates. - Add HSI0 and HSI2 clock controllers. - Mark certain clocks critical. 4. Convert old S3C64xx clock controller bindings to DT schema. ---------------------------------------------------------------- André Draszik (3): dt-bindings: clock: google,gs101-clock: add HSI0 clock management unit clk: samsung: gs101: add support for cmu_hsi0 clk: samsung: gs101: mark some apm UASC and XIU clocks critical Jaewon Kim (1): clk: samsung: exynosautov9: fix wrong pll clock id value Krzysztof Kozlowski (2): dt-bindings: clock: samsung,s3c6400-clock: convert to DT Schema Merge branch 'for-v6.10/clk-gs101-bindings' into next/clk Peter Griffin (2): dt-bindings: clock: google,gs101-clock: add HSI2 clock management unit clk: samsung: gs101: add support for cmu_hsi2 Sam Protsenko (2): clk: samsung: Implement manual PLL control for ARM64 SoCs clk: samsung: exynos850: Add CMU_CPUCL0 and CMU_CPUCL1 Tudor Ambarus (2): clk: samsung: gs101: propagate PERIC0 USI SPI clock rate clk: samsung: gs101: propagate PERIC1 USI SPI clock rate .../bindings/clock/google,gs101-clock.yaml | 55 +- .../bindings/clock/samsung,s3c6400-clock.yaml | 57 + .../bindings/clock/samsung,s3c64xx-clock.txt | 76 -- drivers/clk/samsung/clk-exynos-arm64.c | 56 +- drivers/clk/samsung/clk-exynos850.c | 440 ++++++- drivers/clk/samsung/clk-exynosautov9.c | 8 +- drivers/clk/samsung/clk-gs101.c | 1207 ++++++++++++++++++-- drivers/clk/samsung/clk.h | 15 +- include/dt-bindings/clock/google,gs101.h | 116 ++ 9 files changed, 1822 insertions(+), 208 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/samsung,s3c6400-clock.yaml delete mode 100644 Documentation/devicetree/bindings/clock/samsung,s3c64xx-clock.txt
