Thanks, applied with some minor commit msg changes. In general, please
take care about title prefix (git log --oneline
arch/arm/boot/dts/exynos*) and always explain why you are doing this.
You just mentioned "what" but that is pretty obvious by looking at
commit contents. The commit msg should answer why these should be marked
as opp-suspend and why these values were chosen.
The cover letter just briefly describes "issue with devfreq devices' frequency
during suspend/resume"... but what issue?
Best regards,
Krzysztof
