          Enables the support for SPM and AVS wrapper hardware on MSMs. SPM

          hardware is used to manage the processor power during sleep. The

          driver allows configuring SPM to allow different low power modes for

          both core and L2.



config MSM_L2_SPM

        bool "SPM support for L2 cache"

        help

          Enable SPM driver support for L2 cache. Some MSM chipsets allow

          control of L2 cache low power mode with a Subsystem Power manager.

          Enabling this driver allows configuring L2 SPM for low power modes

          on supported chipsets.
