From: Akihiro Tsukada <tskd08@xxxxxxxxx> Friio device contains "gl861" bridge and "tc90522" demod, for which the separate drivers are already in the kernel. But friio driver was monolithic and did not use them, practically copying those features. This patch decomposes friio driver into sub drivers and re-uses existing ones, thus reduces some code. It adds some features to gl861, to support the friio-specific init/config of the devices and implement i2c communications to the tuner via demod with USB vendor requests.
You should implement i2c adapter to demod driver and not add such glue to that USB-bridge. I mean that "relayed" stuff, i2c communication to tuner via demod. I2C-mux may not work I think as there is no gate-style multiplexing so you probably need plain i2c adapter. There is few examples already on some demod drivers.
