@Judehahh thanks for your PR! In order to set expectations, please note that the feature freeze for Zephyr 3.7 is coming up this Friday, June 14, so there's a high chance your PR might not make into this release, and it might also be a slightly longer than usual until it gets an initial review due to maintainers being busy with release stuff :)

The code looks fine to me, but this needs a rebase (not merge), and the commits should be splitted into multiple logical commits (see #56370)

Thanks, I will rebase when the dependent PR is merged and split it into multiple logical commits.

And I'm so sorry I pressed the "request review" button by mistake...

@Judehahh will you be coming back to this PR?

[Judehahh]

@kartben Yes, I will update once the dependency is merged.

I'll update it when rebase

for the text here, it needs to match the symbol, if you have k230 then you need SOC_SERIES_K230/SOC_K230, if you have canaan_k280 then you need SOC_SERIES_CANAAN_K230/SOC_CANAAN_K230

[Judehahh]

Got it, I'll update it when rebase
