[U-Boot] [PATCH v4 0/7] Fixes/Addition to use the USB Ethernet gadget with the DWC3 gadget controller

[Lukasz Majewski <lukma@denx.de>]

Hi Jean-Jacques,

> 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]"

With the v3 Michal Simek asked (I was out of the office) if we shall
wait for sandbox tests or not?

Is there any follow up plan for adding tests to sandbox?
