arm64: dts: qcom: qcs404: Add DVFS support (cbccc6bc) · Commits · 戴 / test

Support dynamic voltage and frequency scaling on qcs404. CPUFreq will soon be superseded by Core Power Reduction (CPR, a form of Adaptive Voltage Scaling found on some Qualcomm SoCs like the qcs404). Due to the CPR upstreaming already being in progress - and some commits already merged - the following commit will need to be reverted to enable CPUFreq support Author: Jorge Ramirez-Ortiz <jorge.ramirez-ortiz@linaro.org> Date: Thu Jul 25 12:41:36 2019 +0200 cpufreq: Add qcs404 to cpufreq-dt-platdev blacklist Co-developed-by:
