I plan on posting it out end of week. I had sent this series out since a portion (specifically update_ voltage helper and adding opp_tables to cpufreq-hw driver) would remain constant irrespective of the path we choose. FWIW, on SDM845 SoCs we cannot use a rpmh_write_batch based icc_set on cpufreq fast switch pathw since it uses the "wait_for_completion" api. -- -- Sibi Sankar -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project.
