Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ *
+ * sound/wavfront.c
+ *
+ * A Linux driver for Turtle Beach WaveFront Series (Maui, Tropez, Tropez Plus)
+ *
+ * This driver supports the onboard wavetable synthesizer (an ICS2115),
+ * including patch, sample and program loading and unloading, conversion
+ * of GUS patches during loading, and full user-level access to all
+ * WaveFront commands. It tries to provide semi-intelligent patch and
+ * sample management as well.
+ *
+ * It also provides support for the ICS emulation of an MPU-401. Full
+ * support for the ICS emulation's "virtual MIDI mode" is provided in
+ * wf_midi.c.
+ *
+ * Support is also provided for the Tropez Plus' onboard FX processor,
+ * a Yamaha YSS225. Currently, code exists to configure the YSS225,
+ * and there is an interface allowing tweaking of any of its memory
+ * addresses. However, I have been unable to decipher the logical
+ * positioning of the configuration info for various effects, so for
+ * now, you just get the YSS225 in the same state as Turtle Beach's
+ * "SETUPSND.EXE" utility leaves it.
+ *
+ * The boards' DAC/ADC (a Crystal CS4232) is supported by cs4232.[co],
+ * This chip also controls the configuration of the card: the wavefront
+ * synth is logical unit 4.
+ *
+ *
+ * Supported devices:
+ *
+ * /dev/dsp - using cs4232+ad1848 modules, OSS compatible
+ * /dev/midiNN and /dev/midiNN+1 - using wf_midi code, OSS compatible
+ * /dev/synth00 - raw synth interface
+ *
