  • 129eec55d   PM / OPP Introduce APIs to remove OPPs ... Browse Code »

    OPPs are created statically (from DT) or dynamically. Currently we don't free
    OPPs that are created statically, when the module unloads. And so if the module
    is inserted back again, we get warning for duplicate OPPs as the same were
    already present.

    Also, there might be a need to remove dynamic OPPs in future and so API for that
    is also added.

    This patch adds helper APIs to remove/free existing static and dynamic OPPs.

    Because the OPPs are used both under RCU and SRCU, we have to wait for grace
    period of both. And so are using kfree_rcu() from within call_srcu().

  • a0dd7b796   PM / OPP: Move cpufreq specific OPP functions out of generic OPP library ... Browse Code »

    CPUFreq specific helper functions for OPP (Operating Performance Points)
    now use generic OPP functions that allow CPUFreq to be be moved back
    into CPUFreq framework. This allows for independent modifications
    or future enhancements as needed isolated to just CPUFreq framework
    alone.

    Here, we just move relevant code and documentation to make this part of
    CPUFreq infrastructure.
