This patch landed in the Bjorn's tree, however the corresponding driver
change ("cpufreq: qcom: Re-arrange register offsets to support per core
L3 DCVS" / https://patchwork.kernel.org/project/linux-arm-msm/patch/1627581885-32165-3-git-send-email-sibis@codeaurora.org/)
did not land in any maintainer tree yet AFAIK. IIUC the DT change alone
breaks cpufreq since the changed register regions require the changed
offset in the cpufreq driver.

Sibi, please confirm or clarify that my concern is unwarranted.
