[PATCH v2 2/2] dvb-usb-friio: split and merge into dvb-usbv2-gl861

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Akihiro Tsukada <tskd08@xxxxxxxxx>

A Friio device consists of a GL861 adapter/bridge chip,
a TC90522 demod chip and a TUA6034 tuner chip, but
the friio driver was implemented as one combined driver.
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.
