In contrast to other devices using Allwinner SoCs, the Transpeed 8K618-T TV box uses a mainline supported WiFi chip: it's a Broadcom 4335 compatible, packaged by a company called Murata. It works nicely with the Linux driver, when providing the respective firmware files. Add the required DT nodes to let the kernel find the SDIO device.
