- * struct pm_ops - Callbacks for managing platform dependent system sleep
- *      states.
- *
- * @valid: Callback to determine if given system sleep state is supported by
- *      the platform.
- *      Valid (ie. supported) states are advertised in /sys/power/state.  Note
- *      that it still may be impossible to enter given system sleep state if the
- *      conditions aren't right.
- *      There is the %pm_valid_only_mem function available that can be assigned
- *      to this if the platform only supports mem sleep.
- *
- * @set_target: Tell the platform which system sleep state is going to be
- *      entered.
- *      @set_target() is executed right prior to suspending devices.  The
- *      information conveyed to the platform code by @set_target() should be
- *      disregarded by the platform as soon as @finish() is executed and if
- *      @prepare() fails.  If @set_target() fails (ie. returns nonzero),
- *      @prepare(), @enter() and @finish() will not be called by the PM core.
- *      This callback is optional.  However, if it is implemented, the argument
- *      passed to @prepare(), @enter() and @finish() is meaningless and should
- *      be ignored.
- *
- * @prepare: Prepare the platform for entering the system sleep state indicated
- *      by @set_target() or represented by the argument if @set_target() is not
- *      implemented.
- *      @prepare() is called right after devices have been suspended (ie. the
- *      appropriate .suspend() method has been executed for each device) and
- *      before the nonboot CPUs are disabled (it is executed with IRQs enabled).
- *      This callback is optional.  It returns 0 on success or a negative
- *      error code otherwise, in which case the system cannot enter the desired
- *      sleep state (@enter() and @finish() will not be called in that case).
- *
- * @enter: Enter the system sleep state indicated by @set_target() or
- *      represented by the argument if @set_target() is not implemented.
- *      This callback is mandatory.  It returns 0 on success or a negative
- *      error code otherwise, in which case the system cannot enter the desired
- *      sleep state.
- *
- * @finish: Called when the system has just left a sleep state, right after
- *      the nonboot CPUs have been enabled and before devices are resumed (it is
- *      executed with IRQs enabled).  If @set_target() is not implemented, the
- *      argument represents the sleep state being left.
- *      This callback is optional, but should be implemented by the platforms
- *      that implement @prepare().  If implemented, it is always called after
- *      @enter() (even if @enter() fails).
