On MSM, cpus independently scale both frequency and voltage. Our clock driver isn't upstream yet. David Brown has a preliminary version here: https://www.codeaurora.org/gitweb/quic/kernel/?p=davidb/linux-msm.git;a=shortlog;h=refs/heads/msm-clock-rfc Once we get our driver upstream, MSM will be an exception and not select ARM_GENERIC_CPUFREQ. We'll probably have a separate msm-cpufreq.c driver under drivers/cpufreq/. - Bryan -- Sent by an employee of the Qualcomm Innovation Center, Inc.
