Current implementation of snd-firewire-lib can handle only AMDTP transmit
stream with PCM. This series of patch enable it to handle both AMDTP receive
and transmit stream with PCM according to IEC 61883-6.

I develop with Echo Audio's Fireworks (AudioFirePre8). Unfortunately it's not
fully compliant to IEC 61883-6. The last patch includes some work arounds for
Fireworks. The snd-fireworks is still under development and not prepared for

Takashi Sakamoto (4):
  Rename functions, structure and member name for AMDTP
  Add macros for fixed value related to AMDTP
  Add "direction" member to amdtp_stream structure for AMDTP
  Add handling AMDTP receive stream
