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. v2: * Incorporated Viresh's comments from: [1]https://lore.kernel.org/lkml/20190410102429.r6j6brm5kspmqxc3@vireshk-i7/ [2]https://lore.kernel.org/lkml/20190410112516.gnh77jcwawvld6et@vireshk-i7/ Sibi Sankar (4): 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 arch/arm64/boot/dts/qcom/sdm845.dtsi | 343 +++++++++++++++++++++++++++ drivers/cpufreq/qcom-cpufreq-hw.c | 77 +++++- drivers/opp/core.c | 98 ++++++++ include/linux/pm_opp.h | 16 ++ 4 files changed, 532 insertions(+), 2 deletions(-)
