Leaving aside Realtek's involvement, Radxa, one of AIC's downstream
vendors, claims that AIC clarified to them that the entire AIC8800
driver is licensed under GPLv2.[1]

We (deepin) and several downstream vendors are working to clarify the
redistribution license for the AIC8800 firmware, and this remains
unclear to date.
