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!

+ * Driver p16v chips
+ * Version: 0.22
+ *
+ * FEATURES currently supported:
+ * Output fixed at S32_LE, 2 channel to hw:0,0
+ * Rates: 44.1, 48, 96, 192.
+ *
+ * Changelog:
+ * 0.8
+ * Use separate card based buffer for periods table.
+ * 0.9
+ * Use 2 channel output streams instead of 8 channel.
+ * (8 channel output streams might be good for ASIO type output)
+ * Corrected speaker output, so Front -> Front etc.
+ * 0.10
+ * Fixed missed interrupts.
+ * 0.11
+ * Add Sound card model number and names.
+ * Add Analog volume controls.
+ * 0.12
+ * Corrected playback interrupts. Now interrupt per period, instead of half period.
+ * 0.13
+ * Use single trigger for multichannel.
+ * 0.14
+ * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
+ * 0.15
+ * Force buffer_size / period_size == INTEGER.
+ * 0.16
+ * Update p16v.c to work with changed alsa api.
+ * 0.17
+ * Update p16v.c to work with changed alsa api. Removed boot_devs.
+ * 0.18
+ * Merging with snd-emu10k1 driver.
+ * 0.19
+ * One stereo channel at 24bit now works.
+ * 0.20
+ * Added better register defines.
+ * 0.21
+ * Integrated with snd-emu10k1 driver.
+ * 0.22
+ * Removed #if 0 ... #endif
+ *
+ *
+ * BUGS:
+ * Some stability problems when unloading the snd-p16v kernel module.
+ * --
+ *
+ * TODO:
+ * SPDIF out.
+ * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
+ * Currently capture fixed at 48000Hz.

+ * Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
+ * Driver p16v chips
+ * Version: 0.21
+ *
+ * FEATURES currently supported:
+ * Output fixed at S32_LE, 2 channel to hw:0,0
+ * Rates: 44.1, 48, 96, 192.
+ *
+ * Changelog:
+ * 0.8
+ * Use separate card based buffer for periods table.
+ * 0.9
+ * Use 2 channel output streams instead of 8 channel.
+ * (8 channel output streams might be good for ASIO type output)
+ * Corrected speaker output, so Front -> Front etc.
+ * 0.10
+ * Fixed missed interrupts.
+ * 0.11
+ * Add Sound card model number and names.
+ * Add Analog volume controls.
+ * 0.12
+ * Corrected playback interrupts. Now interrupt per period, instead of half period.
+ * 0.13
+ * Use single trigger for multichannel.
+ * 0.14
+ * Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
+ * 0.15
+ * Force buffer_size / period_size == INTEGER.
+ * 0.16
+ * Update p16v.c to work with changed alsa api.
+ * 0.17
+ * Update p16v.c to work with changed alsa api. Removed boot_devs.
+ * 0.18
+ * Merging with snd-emu10k1 driver.
+ * 0.19
+ * One stereo channel at 24bit now works.
+ * 0.20
+ * Added better register defines.
+ * 0.21
+ * Split from p16v.c
+ *
+ *
+ * BUGS:
+ * Some stability problems when unloading the snd-p16v kernel module.
+ * --
+ *
+ * TODO:
+ * SPDIF out.
+ * Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
+ * Currently capture fixed at 48000Hz.

+/* Previously the voice allocator started at 0 every time. The new voice
+ * allocator uses a round robin scheme. The next free voice is tracked in
+ * the card record and each allocation begins where the last left off. The
+ * hardware requires stereo interleaved voices be aligned to an even/odd
+ * boundary. For multichannel voice allocation we ensure than the block of
+ * voices does not cross the 32 voice boundary. This simplifies the
+ * multichannel support and ensures we can use a single write to the
+ * (set|clear)_loop_stop registers. Otherwise (for example) the voices would
+ * get out of sync when pausing/resuming a stream.
