This patch separates off the each chip drivers and re-uses the existing modules: dvb-usbv2-gl861,tc90522. It also adds some modifications to gl861, to support the black-boxed init/config of friio devices and implement an usb vendor request that is used for relay'ed i2c communications to a tuner via a demod.
