Subject: [PATCH] test/py: Add usb gadget binding test
Add a specific usb gadget binding test which check that
binding a driver without compatible string is working as expected.
the command "bind /usb@1 usb_ether" should give the following "dm tree"
command output:
[...]
usb 0 [ ] usb_sandbox |-- usb@1
usb_hub 0 [ ] usb_hub | |-- hub
usb_emul 0 [ ] usb_sandbox_hub | | `-- hub-emul
usb_emul 1 [ ] usb_sandbox_flash | | |-- flash-stick@0
usb_emul 2 [ ] usb_sandbox_flash | | |-- flash-stick@1
usb_emul 3 [ ] usb_sandbox_flash | | |-- flash-stick@2
usb_emul 4 [ ] usb_sandbox_keyb | | `-- keyb@3
eth 4 [ ] usb_ether | `-- usb@1
