I realize it's been about four months since you sent this email, but
if you're still looking for sources for the downstream driver, I know
they're included in the source code releases for the Amazon Fire TV
Stick 4K[1] (latest one here[2]). Inside that tarball, there's a
"platform.tar" archive. Inside "platform.tar" you'll find the kernel
sources for the Fire TV Stick 4K, which includes the WiFi driver for
the MT7668 and several other devices. Specifically, you'll find the
MT7668 drivers under
"kernel/mediatek/mt8695/4.4/drivers/misc/mediatek/connectivity/wlan/gen4"
and "vendor/amazon/wlan/mediatek/driver/mt76x8" (not sure what the
difference is).

I, too, am interested in upstream support for the MT7668 since I have
several USB dongles (well, technically they use custom connectors and
are custom-made to be used inside specific TVs[3], but they enumerate
fine on a normal PC) with the USB variant of that chip, so if anyone
has any plans to add that support, I'd also like to know. And if
someone is interested in doing this and needs hardware, devices that
use the USB variant of the MT7668 are pretty widely available and can
easily be found with this eBay search URL[4]. The user manual[3] for
the devices listed in that search has the pinout for the custom
connector on the board, so it's relatively straightforward to solder
up a USB cable to it to get it working with a computer.
