From 859f0277a6c3ba59b0a5a1eb183f8f6ce661a95d Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 28 Mar 2009 08:29:00 -0300 Subject: [PATCH] V4L/DVB (11278): bttv: convert to v4l2_subdev since i2c autoprobing will disappear. Since i2c autoprobing will disappear bttv needs to be converted to use v4l2_subdev instead. Without autoprobing the autoload module option has become obsolete. A warning is generated if it is set, but it is otherwise ignored. Since the bttv card definitions are of questionable value a new option was introduced to allow the user to control which audio module is selected: msp3400, tda7432 or tvaudio (or none at all). By default bttv will use the card definitions and fallback on tvaudio as the last resort. If no audio device was found a warning is printed. The saa6588 RDS device is now also explicitly probed since it is no longer possible to autoprobe it. A new saa6588 module option was added to override the card definition since I suspect more cards have this device than one would guess from the card definitions. Note that the probe addresses of the i2c modules are hardcoded in this driver. Once all v4l drivers are converted to v4l2_subdev this will be cleaned up. Such data belongs in an i2c driver header.
