[PATCH v3 2/2] arm64: dts: qcom: sc7280: Add cpu OPP tables

From: Sibi Sankar
Date: Wed May 12 2021 - 04:12:02 EST


Add OPP tables required to scale DDR/L3 per freq-domain on SC7280 SoCs.

Reviewed-by: Douglas Anderson <dianders@xxxxxxxxxxxx>

V3:
* Rename cpu opp table nodes [Matthias]
* Rename opp phandles [Doug]

Depends on the following patch series:
L3 Provider Support: https://lore.kernel.org/lkml/1618556290-28303-1-git-send-email-okukatla@xxxxxxxxxxxxxx/
CPUfreq Support: https://lore.kernel.org/lkml/1618020280-5470-2-git-send-email-tdas@xxxxxxxxxxxxxx/
RPMH Provider Support: https://lore.kernel.org/lkml/1619517059-12109-1-git-send-email-okukatla@xxxxxxxxxxxxxx/

It also depends on L3 and cpufreq dt nodes from the ^^ series to not have
overlapping memory regions.
