- * @prepare: Prepare the platform for the given suspend state. Can return a
- *      negative error code if necessary.
+ * @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

+ *      to this if the platform only supports mem sleep.
  *
- * @enter: Enter the given suspend state, must be assigned. Can return a
- *      negative error code if necessary.
+ * @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.
  *
- * @finish: Called when the system has left the given state and all devices
- *      are resumed. The return value is 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).
