Subject: [PATCH v6 0/5] DDR/L3 Scaling support on SDM845 and SC7180 SoCs
Date: Sat, 6 Jun 2020 03:03:27 +0530 [thread overview]
Message-ID: <20200605213332.609-1-sibis@codeaurora.org> (raw)
This patch series aims to extend cpu based scaling support to L3/DDR on
SDM845 and SC7180 SoCs.
Patches [1-2] - Blacklist SDM845 and SC7180 in cpufreq-dt-platdev
Patches [3-5] - Update bw levels based on cpu frequency change
Based on Viresh's opp-next:
https://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git/log/?h=opp/linux-next
V6:
* Add global flag to distinguish between voltage update and opp add.
Use the same flag before trying to scale ddr/l3 bw [Viresh]
* Use dev_pm_opp_find_freq_ceil to grab all opps [Viresh]
* Move dev_pm_opp_of_find_icc_paths into probe [Viresh]
V5:
* Pick up R-bs from Amit
* Drop icc tag support/dt changes till the a consensus is achieved
* Use dev_pm_opp_adjust_voltage instead [Viresh]
* Drop dev_pm_opp_get_path_count [Saravana]
* Rework dev_pm_opp_set_bw
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 (5):
cpufreq: blacklist SDM845 in cpufreq-dt-platdev
cpufreq: blacklist SC7180 in cpufreq-dt-platdev
OPP: Add and export helper to set bandwidth
cpufreq: qcom: Update the bandwidth levels on frequency change
cpufreq: qcom: Disable fast switch when scaling DDR/L3
