Subject: Re: [PATCH v3 13/14] arm64: dts: qcom: qcs404: Add DVFS support

I actually think that it makes sense to squash this patch with the
[PATCH v3 10/14] arm64: dts: qcom: qcs404: Add OPP table
patch.

But that might be a personal preference.

Either way, I think this series in ready for the real mailing list.
