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: https://lore.kernel.org/patchwork/cover/1230626/ 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 Sibi Sankar (12): arm64: dts: qcom: sdm845: Add SoC compatible to MTP cpufreq: blacklist SDM845 in cpufreq-dt-platdev cpufreq: blacklist SC7180 in cpufreq-dt-platdev 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 OPP: Add and export helper to get icc path count cpufreq: qcom: Disable fast switch when scaling ddr/l3 dt-bindings: interconnect: Add interconnect-tags bindings OPP: Add support for setting interconnect-tags arm64: dts: qcom: sdm845: Add cpu OPP tables arm64: dts: qcom: sc7180: Add cpu OPP tables .../bindings/interconnect/interconnect.txt | 5 + arch/arm64/boot/dts/qcom/sc7180.dtsi | 168 ++++++++++++ arch/arm64/boot/dts/qcom/sdm845-mtp.dts | 2 +- arch/arm64/boot/dts/qcom/sdm845.dtsi | 258 ++++++++++++++++++ drivers/cpufreq/cpufreq-dt-platdev.c | 2 + drivers/cpufreq/qcom-cpufreq-hw.c | 89 +++++- drivers/opp/core.c | 114 ++++++++ drivers/opp/of.c | 25 +- include/linux/pm_opp.h | 22 ++ 9 files changed, 675 insertions(+), 10 deletions(-)
