Hi,

This patchset is to add support for Mark of the unicorn (MOTU) 828 and
896, which were shipped two decades ago (2001) and already discontinued.
(yes, it's 2021).

It's reasonable to count them as first generation of MOTU FireWire
series since they are based on QuickLogic QuickRAM FPGA apart from
Altera or Xilinx FPGA in the latter generation. Unlike the latter
generation, they doesn't allow software to configure internal
multiplexer.

I note that the sequence replay for media clock recovery[1] allows to
support them. The device doesn't generate better sound with nominal (ideal)
sequence of packets, thus the patches should be applied to development
tree for v5.14 kernel.
