2008-03-20 11:01:00 net2272 power management
Chris Gourley (UNITED STATES)
We are trying to add power management to a handheld device built around the BF561. The device can be put into standby mode and woke up using a GPIO. However, when the net2272 driver is loaded, the kernel crashes while putting the BF561 into sleep mode with a CPLB miss on an instruction fetch. For a work around I am loading and unloading the net2272 module as needed. I had to add device_unregister() to net2272_remove() to properly remove the module. Any suggestions on how to properly put the net2272 to sleep.

Message: 52848 the net2272 driver needs to have the .suspend and .resume functions implemented ... they arent currently which means that loading/unloading the driver is the next best solution
you can look at the bfin_mac driver as a similar sort of thing of what needs to happen in the suspend/resume functions
