210Driver Detach Power Management
211
212The kernel now supports the ability to place a device in a low-power
213state when it is detached from its driver, which happens when its
214module is removed.
215
216Each device contains a 'detach_state' file in its sysfs directory
217which can be used to control this state. Reading from this file
218displays what the current detach state is set to. This is 0 (On) by
219default. A user may write a positive integer value to this file in the
220range of 1-4 inclusive.
221
222A value of 1-3 will indicate the device should be placed in that
223low-power state, which will cause ->suspend() to be called for that
224device. A value of 4 indicates that the device should be shutdown, so
225->shutdown() will be called for that device.
226
227The driver is responsible for reinitializing the device when the
228module is re-inserted during it's ->probe() (or equivalent) method.
229The driver core will not call any extra functions when binding the
230device to the driver.
