From 46e2856b8e188949757c9123fd7f9ce36edd1a52 Mon Sep 17 00:00:00 2001 From: Ilia Lin Date: Wed, 30 May 2018 05:39:28 +0300 Subject: cpufreq: Add Kryo CPU scaling driver In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors, the CPU frequency subset and voltage value of each OPP varies based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables defines the voltage and frequency value based on the msm-id in SMEM and speedbin blown in the efuse combination. The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC to provide the OPP framework with required information. This is used to determine the voltage and frequency value for each OPP of operating-points-v2 table when it is parsed by the OPP framework.
