[PATCH v4 00/12] DDR/L3 Scaling support on SDM845 and SC7180 SoCs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
