Subject: [PATCH RFC 0/4] DDR/L3 Scaling support on SDM845 SoCs

This RFC series aims to extend cpu based scaling support to L3/DDR on
SDM845 SoCs. The patch series depends on "Introduce OPP bandwidth bindings"
series (https://patchwork.kernel.org/cover/10912993/). A part of the
series will still be applicable if we decide to go ahead with the proposal
from Saravana as well so I decided to post this out.

  OPP: Add and export helper to update voltage
  OPP: Add and export helper to set bandwidth
  cpufreq: qcom: Update the bandwidth levels on frequency change
  arm64: dts: qcom: sdm845: Add cpu OPP tables
