This patch series aims to extend cpu based scaling support to L3/DDR on
SDM845 and SC7180 SoCs.

Patches [1-3] - Blacklist SDM845 and SC7180 in cpufreq-dt-platdev
Patches [4-8] - Update bw levels based on cpu frequency change
Patches [9-10] - Add tag setting support to OPP
Patches [11-12] - Add the cpu opp tables for SDM845 and SC7180 SoCs.

Depends on the following series:

Georgi,
Would it make sense to include tag support patches [9-10] in your next
re-spin?

V4:
* Migrate to using Georgi's new bindings
* Misc fixups based on Matthias comments
* API fixups based on Bjorn's comments on v2
* Picked up a few R-bs from Matthias

v3:
* Migrated to using Saravana's opp-kBps bindings [1]
* Fixed some misc comments from Rajendra
* Added support for SC7180

v2:
* Incorporated Viresh's comments from:
https://lore.kernel.org/lkml/20190410102429.r6j6brm5kspmqxc3@vireshk-i7/
https://lore.kernel.org/lkml/20190410112516.gnh77jcwawvld6et@vireshk-i7/
* Dropped cpufreq-map passive governor
