Takashi Sakamoto3149ac42014-04-25 22:45:26 +090013 * Just powering on, Firewire 410/Audiophile/1814 and ProjectMix I/O wait to
Takashi Sakamoto9076c222014-04-25 22:45:25 +090014 * download firmware blob. To enable these devices, drivers should upload
15 * firmware blob and send a command to initialize configuration to factory
16 * settings when completing uploading. Then these devices generate bus reset
17 * and are recognized as new devices with the firmware.
18 *
Takashi Sakamotoa2b2a772014-04-25 22:45:29 +090019 * But with firmware version 5058 or later, the firmware is stored to flash
20 * memory in the device and drivers can tell bootloader to load the firmware
21 * by sending a cue. This cue must be sent one time.
22 *
Takashi Sakamoto9076c222014-04-25 22:45:25 +090023 * For streaming, both of output and input streams are needed for Firewire 410
24 * and Ozonic. The single stream is OK for the other devices even if the clock
25 * source is not SYT-Match (I note no devices use SYT-Match).
26 *
27 * Without streaming, the devices except for Firewire Audiophile can mix any
28 * input and output. For this reason, Audiophile cannot be used as standalone
29 * mixer.
Takashi Sakamoto3149ac42014-04-25 22:45:26 +090030 *
31 * Firewire 1814 and ProjectMix I/O uses special firmware. It will be freezed
32 * when receiving any commands which the firmware can't understand. These
33 * devices utilize completely different system to control. It is some
34 * write-transaction directly into a certain address. All of addresses for mixer
35 * functionality is between 0xffc700700000 to 0xffc70070009c.
