Hi,

There used to be a company called Miglia Technologies Ltd. in the UK,
and the company was selling a product called Harmony Audio in 2004. Upon
obtaining the product by chance recently and examining its internals, it
was revealed that it utilizes Oxford Semiconductor OXFW970 for its
communication function in IEEE 1394 bus.

This patchset adds support for the model.

Takashi Sakamoto (4):
  ALSA: oxfw: use const qualifier for immutable argument
  ALSA: oxfw: support the case that AV/C Stream Format Information
    command is not available
  ALSA: firewire-lib: handle quirk to calculate payload quadlets as data
    block counter
  ALSA: oxfw: add support for Miglia Harmony Audio
