There was quite a bit of discussion about the change that required the unbinding of USB devices for the subsystem to function correctly. E.g.
https://patchwork.ozlabs.org/patch/485637/
The key issue is the usb_get_dev_index() function which is not a good API for driver model. We can drop use of this function once everything is converted to driver model. Then I believe the problems raised by Hans go away. For now we can add a deprecation warning on the function.
It is easy to convert USB keyboards to driver model. This series includes a patch for that.
This series also includes reverts for the three commits which as discussed I would like to drop. U-Boot should be able to run normally and exit without unbinding anything.
Also included are some tests for the 'usb tree' command. To make this work, console recording is implemented.
Finally, a USB keyboard driver is provided for sandbox, so that this part of the stack can be tested automatically.
Changes in v2:
- Add various patches to support USB keyboards and additional tests
