Patchset:
PS1: I had also started some updated documentation for debugging at CB:85913
File Documentation/technotes/console.md:

Though it does seem like all of these should still work by selecting `CONFIG_USBDEBUG_DONGLE_STD`, judging from the help text for that option. Using a supported USB to serial adapter or the USB gadget driver would probably be the most relevant options nowadays.
