+ * We make no difference between IDLE and RUNNING in our handling.
+ *
+ * As long as we are in RUNNING/IDLE state we will *always* write data to

+ *
+ * If power should be saved on IDLE this should be implemented in a
+ * special suspend-on-idle module that will put us into SUSPEND mode
+ * as soon and we're idle for too long.
