From ee4b9dbb83c73c5408d7f479a501551a63ec57d3 Mon Sep 17 00:00:00 2001 From: Richard Röjfors Date: Tue, 2 Feb 2010 19:40:49 -0300 Subject: V4L/DVB: radio: add support for SAA7706H Car Radio DSP MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Initial support for the SAA7706H Car Radio DSP. It is a I2C device and currently the mute control is supported. When the device is unmuted it is brought out of reset and initiated using the proposed intialisation sequence. When muted the DSP is brought into reset state.

It's a In-Vehicle Infotainment board with a radio tuner and DSP. This umbrella driver has the DSP and tuner as V4L2 subdevs and calls them when needed.
