      ALSA: fireworks: Add command/response functionality into hwdep interface · 555e8a8f
      Takashi Sakamoto authored
      This commit adds two functionality for hwdep interface, adds two parameters for
      this driver, add a node for proc interface.
      
      To receive responses from devices, this driver already allocate own callback
      into initial memory space in host controller. This means no one can allocate
      its own callback to the address. So this driver must give a way for user
      applications to receive responses.
      
      This commit adds a functionality to receive responses via hwdep interface. The
      application can receive responses to read from this interface. To achieve this,
      this commit adds a buffer to queue responses. The default size of this buffer is
      1024 bytes. This size can be changed to give preferrable size to
      'resp_buf_size' parameter for this driver. The application should notice rest
      of space in this buffer because this driver don't push responses when this
      buffer has no space.
      
      Additionaly, this commit adds a functionality to transmit commands via hwdep
      interface. The application can transmit commands to write into this interface.
      I note that the application can transmit one command at once, but can receive
      as many responses as possible untill the user-buffer is full.
      
      When using these interfaces, the application must keep maximum number of
      sequence number in command within the number in firewire.h because this driver
      uses this number to distinguish the response is against the command by the
      application or this driver.
      
      Usually responses against commands which the application transmits are pushed
      into this buffer. But to enable 'resp_buf_debug' parameter for this driver, all
      responses are pushed into the buffer. When using this mode, I reccomend to
      expand the size of buffer.
      
      Finally this commit adds a new node into proc interface to output status of the
      buffer.

      ALSA: fireworks: Add hwdep interface · 594ddced
      Takashi Sakamoto authored
      This interface is designed for mixer/control application. To use hwdep
      interface, the application can get information about firewire node, can
      lock/unlock kernel streaming and can get notification at starting/stopping
      kernel streaming.

      ALSA: fireworks/firewire-lib: Add a quirk for fixed interval of reported dbc · d9cd0065
      Takashi Sakamoto authored
      Fireworks firmware version 5.5 reports fix interval for dbc in each packet.
      
      For example, AudioFire4:
      CIP0     CIP1     Payload
      00070000 900484FF 72
      00070008 9004A8FF 72
      00070008 90FFFFFF 02
      00070010 9004D0FF 72
      00070018 9004C4FF 72
      00070020 9004E8FF 72
      00070020 90FFFFFF 02
      00070028 900410FE 72
      
      The interval of each dbc should be 16 except for empty packet but it's still 8.
      
      This commit adds a flag for this quirk and codes to refer to a fixed value.

      ALSA: fireworks/firewire-lib: Add a quirk for the meaning of dbc · c8bdf49b
      Takashi Sakamoto authored
      Fireworks has a quirk for the value of dbc field in transmitted packets.
      For Fireworks, dbc means the end of events in current packet. This is out
      of specification.
      
      For example, AudioFire4:
      CIP0        CIP1    Payload
      01070092 90FFFFFF 02
      0107009A 9001E17B 3A <-
      010700A2 9001F6E5 3A
      010700A2 90FFFFFF 02
      010700AA 9001104F 3A <-
      010700B2 900125B9 3A
      010700BA 90013B23 3A
      010700BA 90FFFFFF 02
      010700C2 9001548E 3A <-
      010700CA 900169F8 3A
      010700CA 90FFFFFF 02
      010700D2 90018362 3A <-
      010700DA 900198CC 3A
      
      According to IEC 61883-1/6, a packet following to empty packet has the same
      value for its dbc. But for Fireworks, it's incremented and empty packet has
      the same value as previous packet in dbc field.
      
      This commit adds a flag for Fireworks and some codes to checking dbc continuity.

      ALSA: fireworks: Add connection and stream management · 315fd41f
      Takashi Sakamoto authored
      Fireworks manages connections by CMP and can transmit/receive AMDTP streams
      with a few quirks. This commit adds functionality to start/stop the streams.
      
      Major Fireworks products don't support 'SYT-Match' clock source mode, except
      for AudioFire12/8(till 2009 July) with firmware version 1.0. Already in
      previous commit, this driver don't support such old firmwares. So this commit
      adds support for non 'SYT-Match' clock source modes.
      
      I note that this driver has a short gap for MIDI streams when starting PCM
      stream. When AMDTP streams are running only for MIDI data and PCM data is
      going to be joined at different sampling rate, then AMDTP streams are
      stopped once and started again after changing sampling rate.
      
      Unfortunately, Fireworks is not fully compliant to IEC 61883-1/6. Some commits
      following to this commit add these quirks.

      ALSA: fireworks: Add transaction and some commands · bde8a8f2
      Takashi Sakamoto authored
      Fireworks uses own command and response. This commit adds functionality to
      transact and adds some commands required for sound card instance and kernel
      streaming.
      
      There are two ways to deliver substance of this transaction:
      1.AV/C vendor dependent command for command/response
      2.Async transaction to specific addresses for command/response
      
      By way 1, I confirm AudioFire12 cannot correctly response to some commands with
      firmware version 5.0 or later. This is also confirmed by FFADO. So this driver
      implement way 2.
      
      The address for response gives an issue. When this driver allocate own callback
      function into the address, then no one can allocate its own callback function.
      This situation is not good for applications in user-land. This issue is solved
      in later commit.
      
      I note there is a command to change the address for response if the device
      supports. But this driver uses default value. So users should not execute this
      command as long as hoping this driver works correctly.

      ALSA: fireworks: Add skelton for Fireworks based devices · b5b04336
      Takashi Sakamoto authored
      This commit adds a new driver for devices based on Fireworks. This driver
      just creates/removes card instance according to callbacks.
      
      Fireworks is a board module which Echo Audio produced. This module
      consists of three chipsets:
       - Communication chipset for IEEE1394 PHY/Link and IEC 61883-1/6
       - DSP or/and FPGA for signal processing
       - Flash Memory to store firmwares
      
      Current supported devices:
       - Mackie Onyx 400F/1200F
       - Echo AudioFire12/8(until 2009 July)
       - Echo AudioFire2/4/Pre8/8(since 2009 July)
       - Echo Fireworks 8/HDMI
       - Gibson Robot Interface pack/GoldTop
