[alsa-devel] [PATCH 0/6] ALSA: firewire-motu: add support for MOTU UltraLite and source packet header clock mode
Hi,
Devices in MOTU FireWire series uses source packet header (SPH) in IEC 61883-1 for each data block in CIP. The devices have a mode to use the series of SPH for generating sampling clock.
This patchset supports the above mechanism. Additionally, this patchset also supports MOTU UltraLite which adopts protocol version 2.
Takashi Sakamoto (6): ALSA: firewire-motu: fix wrong spelling for macro ALSA: firewire-motu: print for unknown source of sampling clock ALSA: firewire-motu: detect SPH source of sampling clock ALSA: firewire-motu: minor code refactoring for protocol version 2 ALSA: firewire-motu: code refactoring to handle model specific switch for protocol v2 ALSA: firewire-motu: add support for MOTU UltraLite

Just replace 'SEPARETED' with 'SEPARATED' for macro.

In MOTU FireWire series, devices have a mode to generate sampling clock from a sequence of source packet header (SPH) included in each data block of received packet. This mode is used for several purposes such as mode for SMPTE time code, sync to the other sound cards and so on.
This commit adds support for the SPH mode.

In MOTU FireWire series, devices which support protocol version 2 have several types of hardware design to process audio data frames for isoc packet. Roughly devices are categorized into three groups: - 828mkII - Traveler/896HD - UltraLite/8pre FireWire
Some bit flags in register addressed by 0x'ffff'f000'0b14 includes device-specific effects.
This commit cleanups implementation of protocol v2 in this point.

UltraLite was shipped in 2005 by MOTU, and already discontinued. This model consists of below ICs:
- Texus Instruments TSB41AB2 for physical layer of IEEE 1394 bus - Xilinx Spartan XC35S200 for link layer of IEEE 1394 bus, protocol layer and signal processing
This commit adds support for this model. Like the other MOTU models, ALSA firewire MOTU driver fails to drive the device for stable sampling clock and generate noisy sound.

Hi,
Devices in MOTU FireWire series uses source packet header (SPH) in IEC 61883-1 for each data block in CIP. The devices have a mode to use the series of SPH for generating sampling clock.
This patchset supports the above mechanism. Additionally, this patchset also supports MOTU UltraLite which adopts protocol version 2.
Takashi Sakamoto (6): ALSA: firewire-motu: fix wrong spelling for macro ALSA: firewire-motu: print for unknown source of sampling clock ALSA: firewire-motu: detect SPH source of sampling clock ALSA: firewire-motu: minor code refactoring for protocol version 2 ALSA: firewire-motu: code refactoring to handle model specific switch for protocol v2 ALSA: firewire-motu: add support for MOTU UltraLite
Applied all patches now. Thanks.
