+ *
+ * GPL v2, can be found in COPYING.
+ *
+ *
+ * This is a driver for the pcm3052 codec chip (codenamed Onyx)
+ * that is present in newer Apple hardware (with digital output).
+ *
+ * The Onyx codec has the following connections (listed by the bit
+ * to be used in aoa_codec.connected):
+ *  0: analog output
+ *  1: digital output
+ *  2: line input
+ *  3: microphone input
+ * Note that even though I know of no machine that has for example
+ * the digital output connected but not the analog, I have handled
+ * all the different cases in the code so that this driver may serve
+ * as a good example of what to do.
+ *
+ * NOTE: This driver assumes that there's at most one chip to be
+ * 	 used with one alsa card, in form of creating all kinds
+ *	 of mixer elements without regard for their existence.
+ *	 But snd-aoa assumes that there's at most one card, so
+ *	 this means you can only have one onyx on a system. This
+ *	 should probably be fixed by changing the assumption of
+ *	 having just a single card on a system, and making the
+ *	 'card' pointer accessible to anyone who needs it instead
+ *	 of hiding it in the aoa_snd_* functions...

+ * Apple Onboard Audio driver for tas codec
+ *
+ * Copyright 2006 Johannes Berg <johannes@sipsolutions.net>
+ *
+ * GPL v2, can be found in COPYING.
+ *
+ * Open questions:
+ *  - How to distinguish between 3004 and versions?
+ *
+ * FIXMEs:
+ *  - This codec driver doesn't honour the 'connected'
+ *    property of the aoa_codec struct, hence if
+ *    it is used in machines where not everything is
+ *    connected it will display wrong mixer elements.
+ *  - Driver assumes that the microphone is always
+ *    monaureal and connected to the right channel of
+ *    the input. This should also be a codec-dependent
+ *    flag, maybe the codec should have 3 different
+ *    bits for the three different possibilities how
+ *    it can be hooked up...
+ *    But as long as I don't see any hardware hooked
+ *    up that way...
+ *  - As Apple notes in their code, the tas3004 seems
+ *    to delay the right channel by one sample. You can
+ *    see this when for example recording stereo in
+ *    audacity, or recording the tas output via cable
+ *    on another machine (use a sinus generator or so).
+ *    I tried programming the BiQuads but couldn't
+ *    make the delay work, maybe someone can read the
+ *    datasheet and fix it. The relevant Apple comment
+ *    is in AppleTAS3004Audio.cpp lines 1637 ff. Note
+ *    that their comment describing how they program
+ *    the filters sucks...
+ *
+ * Other things:
+ *  - this should actually register *two* aoa_codec
+ *    structs since it has two inputs. Then it must
+ *    use the prepare callback to forbid running the
+ *    secondary output on a different clock.
+ *    Also, whatever bus knows how to do this must
+ *    provide two soundbus_dev devices and the fabric
+ *    must be able to link them correctly.
+ *
+ *    I don't even know if Apple ever uses the second
+ *    port on the tas3004 though, I don't think their
+ *    i2s controllers can even do it. OTOH, they all
+ *    derive the clocks from common clocks, so it
+ *    might just be possible. The framework allows the
+ *    codec to refine the transfer_info items in the
+ *    usable callback, so we can simply remove the
+ *    rates the second instance is not using when it
+ *    actually is in use.
+ *    Maybe we'll need to make the sound busses have
+ *    a 'clock group id' value so the codec can
+ *    determine if the two outputs can be driven at
+ *    the same time. But that is likely overkill, up
+ *    to the fabric to not link them up incorrectly,
+ *    and up to the hardware designer to not wire
+ *    them up in some weird unusable way.

+
+   Here's a block diagram of how most of the cards work:
+
+                  +-----------+
+           record |           |<-------------------- Inputs
+          <-------|           |        |
+     PCI          | Transport |        |
+     bus          |  engine   |       \|/
+          ------->|           |    +-------+
+            play  |           |--->|monitor|-------> Outputs
+                  +-----------+    | mixer |
+                                   +-------+
+
+   The lines going to and from the PCI bus represent "pipes".  A pipe performs
+   audio transport - moving audio data to and from buffers on the host via
+   bus mastering.
+
+   The inputs and outputs on the right represent input and output "busses."
+   A bus is a physical, real connection to the outside world.  An example
+   of a bus would be the 1/4" analog connectors on the back of Layla or
+   an RCA S/PDIF connector.
+
+   For most cards, there is a one-to-one correspondence between outputs
+   and busses; that is, each individual pipe is hard-wired to a single bus.
+
+   Cards that work this way are Darla20, Gina20, Layla20, Darla24, Gina24,
+   Layla24, Mona, and Indigo.
+
+
+   Mia has a feature called "virtual outputs."
+
+
+                  +-----------+
+           record |           |<----------------------------- Inputs
+          <-------|           |                  |
+     PCI          | Transport |                  |
+     bus          |  engine   |                 \|/
+          ------->|           |   +------+   +-------+
+            play  |           |-->|vmixer|-->|monitor|-------> Outputs
+                  +-----------+   +------+   | mixer |
+                                             +-------+
+
+
+   Obviously, the difference here is the box labeled "vmixer."  Vmixer is
+   short for "virtual output mixer."  For Mia, pipes are *not* hard-wired
+   to a single bus; the vmixer lets you mix any pipe to any bus in any
+   combination.
+
+   Note, however, that the left-hand side of the diagram is unchanged.
+   Transport works exactly the same way - the difference is in the mixer stage.
+
+
+   Pipes and busses are numbered starting at zero.
+
+
+
+   Pipe index
+   ==========
+
+   A number of calls in CEchoGals refer to a "pipe index".  A pipe index is
+   a unique number for a pipe that unambiguously refers to a playback or record
+   pipe.  Pipe indices are numbered starting with analog outputs, followed by
+   digital outputs, then analog inputs, then digital inputs.
+
+   Take Gina24 as an example:
+
+   Pipe index
+
+   0-7            Analog outputs (0 .. FirstDigitalBusOut-1)
+   8-15           Digital outputs (FirstDigitalBusOut .. NumBussesOut-1)
+   16-17          Analog inputs
+   18-25          Digital inputs
+
+
+   You get the pipe index by calling CEchoGals::OpenAudio; the other transport
+   functions take the pipe index as a parameter.  If you need a pipe index for
+   some other reason, use the handy Makepipe_index method.
+
+
+   Some calls take a CChannelMask parameter; CChannelMask is a handy way to
+   group pipe indices.
+
+
+
+   Digital mode switch
+   ===================
+
+   Some cards (right now, Gina24, Layla24, and Mona) have a Digital Mode Switch
+   or DMS.  Cards with a DMS can be set to one of three mutually exclusive
+   digital modes: S/PDIF RCA, S/PDIF optical, or ADAT optical.
+
+   This may create some confusion since ADAT optical is 8 channels wide and
+   S/PDIF is only two channels wide.  Gina24, Layla24, and Mona handle this
+   by acting as if they always have 8 digital outs and ins.  If you are in
+   either S/PDIF mode, the last 6 channels don't do anything - data sent
+   out these channels is thrown away and you will always record zeros.
+
+   Note that with Gina24, Layla24, and Mona, sample rates above 50 kHz are
+   only available if you have the card configured for S/PDIF optical or S/PDIF
+   RCA.
+
+
+
+   Double speed mode
+   =================
+
+   Some of the cards support 88.2 kHz and 96 kHz sampling (Darla24, Gina24,
+   Layla24, Mona, Mia, and Indigo).  For these cards, the driver sometimes has
+   to worry about "double speed mode"; double speed mode applies whenever the
+   sampling rate is above 50 kHz.
+
+   For instance, Mona and Layla24 support word clock sync.  However, they
+   actually support two different word clock modes - single speed (below
+   50 kHz) and double speed (above 50 kHz).  The hardware detects if a single
+   or double speed word clock signal is present; the generic code uses that
+   information to determine which mode to use.
+
+   The generic code takes care of all this for you.

+Setting the sample rates on Layla24 is somewhat schizophrenic.
+
+For standard rates, it works exactly like Mona and Gina24.  That is, for
+8, 11.025, 16, 22.05, 32, 44.1, 48, 88.2, and 96 kHz, you just set the
+appropriate bits in the control register and write the control register.
+
+In order to support MIDI time code sync (and possibly SMPTE LTC sync in
+the future), Layla24 also has "continuous sample rate mode".  In this mode,
+Layla24 can generate any sample rate between 25 and 50 kHz inclusive, or
+50 to 100 kHz inclusive for double speed mode.

+To use continuous mode:
+
+-Set the clock select bits in the control register to 0xe (see the #define
+ below)
+
+-Set double-speed mode if you want to use sample rates above 50 kHz
+
+-Write the control register as you would normally
+
+-Now, you need to set the frequency register. First, you need to determine the
+ value for the frequency register.  This is given by the following formula:
+
+frequency_reg = (LAYLA24_MAGIC_NUMBER / sample_rate) - 2
+
+Note the #define below for the magic number
+
+-Wait for the DSP handshake
+-Write the frequency_reg value to the .SampleRate field of the comm page
+-Send the vector command SET_LAYLA24_FREQUENCY_REG (see vmonkey.h)
+
+Once you have set the control register up for continuous mode, you can just
+write the frequency register to change the sample rate.  This could be
+used for MIDI time code sync. For MTC sync, the control register is set for
+continuous mode.  The driver then just keeps writing the
+SET_LAYLA24_FREQUENCY_REG command.
