63 * Slot states for PIOCGSTATE
65 * Here's a state diagram of all the possible states:
71 * resume +----------+ power x 0 +----------+
72 * ------->| inactive |<--------------| filled |
73 * / +----------+ +----------+
75 * nil <--------- \ insert or | | suspend or
76 * suspend \ power x 1 | | eject
79 * ----------->| empty |
82 * Note, the above diagram is for the state. On suspend, the laststate
83 * gets set to suspend to tell pccardd what happened. Also the nil state
84 * means that when the no state change has happened. Note: if you eject
85 * while suspended in the inactive state, you will return to the
86 * empty state if you do not insert a new card and to the inactive state
87 * if you do insert a new card.
89 * Some might argue that inactive should be sticky forever and
90 * eject/insert shouldn't take it out of that state. They might be
91 * right. On the other hand, some would argue that eject resets all
92 * state. They might be right. They both can't be right. The above
93 * represents a reasonable compromise between the two.
95 * Some bridges allow one to query to see if the card was changed while
96 * we were suspended. Others do not. We make no use of this functionality
