    Subject[PATCH v3 0/6] powernv: cpufreq: Report frequency throttle by OCC
    Date
    This patchset intends to add frequency throttle reporting mechanism
    to powernv-cpufreq driver when OCC throttles the frequency. OCC is an
    On-Chip-Controller which takes care of the power and thermal safety of
    the chip. The CPU frequency can be throttled during an OCC reset or
    when OCC tries to limit the max allowed frequency. The patchset will
    report such conditions so as to keep the user informed about reason
    for the drop in performance of workloads when frequency is throttled.

    Changes from v2:
    - Split into multiple patches
    - Semantic fixes

    Shilpasri G Bhat (6):
    cpufreq: poowernv: Handle throttling due to Pmax capping at chip level
    powerpc/powernv: Add definition of OPAL_MSG_OCC message type
    cpufreq: powernv: Register for OCC related opal_message notification
    cpufreq: powernv: Call throttle_check() on receiving OCC_THROTTLE
    cpufreq: powernv: Report Psafe only if PMSR.psafe_mode_active bit is
    set
    cpufreq: powernv: Restore cpu frequency to policy->cur on unthrottling
