get from dts property using function, and it should be set in soc Kconfig.defconfig file, not by a board

This is the way other boards configure the clock cycles. It's also part of an example here: Board Porting Guide

that documentation is very outdated and needs to be fixed, but this also needs to be fixed, this Kconfig needs to come from a dts value and in the soc Kconfig.defconfig file

I would rather have this changed in a different PR. It should be consistent for all board. And then the documentation should be updated accordingly.

nothing new to be added with the old style, so if the old style remains in this PR then this PR will remain nacked

I believe @LukasWoodtli have already added the required changes in Kconfig.defconfig:

config SYS_CLOCK_HW_CYCLES_PER_SEC default $(dt_node_int_prop_int,/cpus/cpu@0,clock-frequency)

He just forgot to remove the line above from efm32tg_stk3300_defconfig.

Oh, that's good. @LukasWoodtli could you do that last change then?

@LukasWoodtli I see you're pushing updates, but I don't see any change to this? As @jerome-pouiller wrote since you have the info correctly now in DTS it makes the above line redundant.

I removed it from efm32tg_stk3300_defconfig.

@LukasWoodtli thanks. Unfortunately, this missed the Zephyr 4.3 feature freeze, which means that it would have to wait until the merge window opens again in some three weeks.

LGTM

@LukasWoodtli is there a reason why you still want to keep this as a Draft PR?

Wonder or Tiny?

Good catch! Thanks

yishai1999 · 2025-10-21T11:35:34Z

Do the TG and WG socs share characteristics? Can there be a shared dtsi between them?

asmellby · 2025-10-21T11:38:38Z

TG is one of the smallest Series 0 MCUs which a Cortex-M3 core, WG is one of the biggest with a Cortex-M4 core. While they have many of the same peripherals, the peripheral addresses etc are pretty different. So I don't think it makes sense to try sharing much.

asmellby · 2025-10-24T07:04:01Z

This PR needs a rebase. Since another PR that moves the hal_silabs module past the content needed in this PR has been merged, the changes to west.yml can be dropped from this PR.

jhedberg · 2025-10-27T07:39:53Z

@nordicjm could you take another look, since it seems your concerns should have been addressed. Not super urgent though, since this missed the feature freeze.
