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!

Q. [Ports] Why is the base address of the WSS I/O ports off by 4?
A. WSS I/O requires a block of 8 I/O addresses ("ports"). Of these, the first
4 are used to identify and configure the board. With the advent of PnP,
these first 4 addresses have become obsolete, and software applications
only use the last 4 addresses to control the codec chip. Therefore, the
base address setting "skips past" the 4 unused addresses.

/* The low level driver for the WaveFront ICS2115 MIDI interface(s)
*
* Note that there is also an MPU-401 emulation (actually, a UART-401
* emulation) on the CS4232 on the Tropez and Tropez Plus. This code
* has nothing to do with that interface at all.
*
* The interface is essentially just a UART-401, but is has the
* interesting property of supporting what Turtle Beach called
* "Virtual MIDI" mode. In this mode, there are effectively *two*
* MIDI buses accessible via the interface, one that is routed
* solely to/from the external WaveFront synthesizer and the other
* corresponding to the pin/socket connector used to link external
* MIDI devices to the board.
*
* This driver fully supports this mode, allowing two distinct MIDI
* busses to be used completely independently, giving 32 channels of
* MIDI routing, 16 to the WaveFront synth and 16 to the external MIDI
* bus. The devices are named /dev/snd/midiCnD0 and /dev/snd/midiCnD1,
* where `n' is the card number. Note that the device numbers may be
* something other than 0 and 1 if the CS4232 UART/MPU-401 interface
* is enabled.
*
* Switching between the two is accomplished externally by the driver
* using the two otherwise unused MIDI bytes. See the code for more details.
*
* NOTE: VIRTUAL MIDI MODE IS ON BY DEFAULT (see lowlevel/isa/wavefront.c)
*
* The main reason to turn off Virtual MIDI mode is when you want to
* tightly couple the WaveFront synth with an external MIDI
* device. You won't be able to distinguish the source of any MIDI
* data except via SysEx ID, but thats probably OK, since for the most
* part, the WaveFront won't be sending any MIDI data at all.
*
* The main reason to turn on Virtual MIDI Mode is to provide two
* completely independent 16-channel MIDI buses, one to the
* WaveFront and one to any external MIDI devices. Given the 32
* voice nature of the WaveFront, its pretty easy to find a use
* for all 16 channels driving just that synth.
