- * Driver for the i2c/i2s based TA3004 sound chip used

- * Tobias Sargeant <tobias.sargeant@bigpond.com>
- * Based upon, tas3001c.c by Christopher C. Chimelis <chris@debian.org>:
- *
- * TODO:
- * -----
- * * Enable control over input line 2 (is this connected?)
- * * Implement sleep support (at least mute everything and
- * * set gains to minimum during sleep)
- * * Look into some of Darwin's tweaks regarding the mute
- * * lines (delays & different behaviour on some HW)
