This series implements 2 fixes to be able to use USB Ethernet gadget with the dwc3 driver. It also adds new commands to bind/unbind a device to/from a driver and update the 'dm tree' command to make it easier to use those new commands. The bind/unbind commands can be used to bind the DWC3 USB gadget to the usb_ether driver from the command line instead of relying on platform code.
Changes in v4: - Fixed compiler warning: "cmd/bind.c:236:5: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]"
Changes in v3: - update commit log - fixed problem with the function name - update commit log - new commit - new - factorize code based on comments from ML - remove the devices before unbinding them - use device_find_global_by_ofnode() to get a device by its node.
Changes in v2: - Make the bind/unbind command generic, not specific to usb device. - Update the API to be able to bind/unbind based on DTS node path - Add a Kconfig option to select the bind/unbind commands
