ALSA: firewire-digi00x: add proc node to show clock status This commit adds proc node to show current clock status for debugging. As long as testing Digi 002 rack, registers can show local clock rate, local clock source. When external clock input such as S/PDIF is connected, the registers show the detection and external clock rate. Additionally, the registers show the mode of optical digital input interface. Although, a tester with Digi 003 rack reports this makes no sense. Further investigation is required for Digi 003 series. Besides, in Digi 002 rack, the S/PDIF format must be IEC 60958-4, so-called professional. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: firewire-digi00x: add support for asynchronous messaging Digi 002/003 family uses asynchronous transaction for messaging. The address to transmit this message is stored on a certain register. This commit allocates a range of address on OHCI 1394 host controller to handle the messaging. As long as I know, the purpose of this message seems to notify lost of synchronization. While, the meaning of content of the message is not clear. Actual examples of this messaging: * When clock source is set as internal: - 0x00007051 - 0x00007052 - 0x00007054 - 0x00007057 - 0x00007058 * When clock source is set as somewhat external: - 0x00009000 - 0x00009010 - 0x00009020 - 0x00009021 - 0x00009022 The lost often occurs when using internal clock source. In this case, users hear sounds with quite short gap every several minutes. In fact, the lost is recovered temporarily. When using with external clock source, the lost seems not to occur. The mechanism is not clear yet. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: firewire-digi00x: add support for MIDI ports corresponding to isochronous packet streaming This commit adds MIDI functionality to capture/playback MIDI messages from/to physical MIDI ports. These messages are transferred in isochronous packets. When no substreams request AMDTP streams to run, this driver starts the streams at current sampling rate. When other substreams start at different sampling rate, the streams are stopped temporarily, then start again at requested sampling rate. This operation can generate missing MIDI bytes, thus it's preferable to start PCM substreams at favorite sampling rate in advance. Digi 002/003 console also has a set of MIDI port for physical controls. These ports are added in later commits.

ALSA: firewire-digi00x: add skeleton for Digi 002/003 family This commit adds a new driver for Digidesign 002/003 family. This commit just creates/removes card instance according to bus event. More functions will be added in following commits. Digidesign 002/003 family consists of: * Agere FW802B for IEEE 1394 PHY layer * PDI 1394L40 for IEEE 1394 LINK layer and IEC 61883 interface * ALTERA ACEX EP1K50 for IEC 61883 layer and DSP controller * ADSP-21065L for signal processing [minor cleanup using skip_spaces() by tiwai] Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
