2 | * For the STS-Thompson TDA7432 audio processor chip | |
3 | * | |
4 | * Handles audio functions: volume, balance, tone, loudness | |
5 | * This driver will not complain if used with any | |
6 | * other i2c device with the same address. | |

8 | * Muting and tone control by Jonathan Isom <jisom@ematic.com> | |

10 | * Copyright (c) 2000 Eric Sandeen <eric_sandeen@bigfoot.com> | |
11 | * This code is placed under the terms of the GNU General Public License | |
12 | * Based on tda9855.c by Steve VanDeBogart (vandebo@uclink.berkeley.edu) | |
13 | * Which was based on tda8425.c by Greg Alexander (c) 1998 | |
14 | * | |
15 | * OPTIONS: | |
16 | * debug - set to 1 if you'd like to see debug messages | |
17 | * set to 2 if you'd like to be inundated with debug messages | |
18 | * | |
19 | * loudness - set between 0 and 15 for varying degrees of loudness effect | |
20 | * | |
21 | * maxvol - set maximium volume to +20db (1), default is 0db(0) | |
22 | * | |
23 | * | |
24 | * Revision: 0.7 - maxvol module parm to set maximium volume 0db or +20db | |
25 | * store if muted so we can return it | |
26 | * change balance only if flaged to | |
27 | * Revision: 0.6 - added tone controls | |
28 | * Revision: 0.5 - Fixed odd balance problem | |
29 | * Revision: 0.4 - added muting | |
30 | * Revision: 0.3 - Fixed silly reversed volume controls. :) | |
31 | * Revision: 0.2 - Cleaned up #defines | |
32 | * fixed volume control | |
33 | * Added I2C_DRIVERID_TDA7432 | |
34 | * added loudness insmod control | |
35 | * Revision: 0.1 - initial version | |

100 | * The TDA7432 controls basic audio functions like volume, balance, | |

104 | * together (no independent control). | |
