* Just powering on, Firewire 410/Audiophile/1814 and ProjectMix I/O wait to
* download firmware blob. To enable these devices, drivers should upload
* firmware blob and send a command to initialize configuration to factory
* settings when completing uploading. Then these devices generate bus reset
* and are recognized as new devices with the firmware.
*
* But with firmware version 5058 or later, the firmware is stored to flash
* memory in the device and drivers can tell bootloader to load the firmware
* by sending a cue. This cue must be sent one time.
*
* For streaming, both of output and input streams are needed for Firewire 410
* and Ozonic. The single stream is OK for the other devices even if the clock
* source is not SYT-Match (I note no devices use SYT-Match).
*
* Without streaming, the devices except for Firewire Audiophile can mix any
* input and output. For this reason, Audiophile cannot be used as standalone
* mixer.
*
* Firewire 1814 and ProjectMix I/O uses special firmware. It will be freezed
* when receiving any commands which the firmware can't understand. These
* devices utilize completely different system to control. It is some
* write-transaction directly into a certain address. All of addresses for mixer
* functionality is between 0xffc700700000 to 0xffc70070009c.

* NOTE:
* Yamaha GO44 is not designed to be used as stand-alone mixer. So any streams
* must be accompanied. If changing the state, a LED on the device starts to
* blink and its sync status is false. In this state, the device sounds nothing
* even if streaming. To start streaming at the current sampling rate is only
* way to revocer this state. GO46 is better for stand-alone mixer.
*
* Both of them have a capability to change its sampling rate up to 192.0kHz.
* At 192.0kHz, the device reports 4 PCM-in, 1 MIDI-in, 6 PCM-out, 1 MIDI-out.
* But Yamaha's driver reduce 2 PCM-in, 1 MIDI-in, 2 PCM-out, 1 MIDI-out to use
* 'Extended Stream Format Information Command - Single Request' in 'Additional
* AVC commands' defined by BridgeCo.
* This ALSA driver don't do this because a bit tiresome. Then isochronous
* streaming with many asynchronous transactions brings sounds with noises.
* Unfortunately current 'ffado-mixer' generated many asynchronous transaction
* to observe device's state, mainly check cmp connection and signal format. I
* reccomend users to close ffado-mixer at 192.0kHz if mixer is needless.
