2ef0b7cf16 ALSA: firewire-tascam: code refactoring for registration of isochronous channels
This commit is a part of preparation to perform allocation/release
of isochronous channels in pcm.hw_params/hw_free callbacks.

The registration of isochronous channels is done just after allocation
of isochronous resources. This commit separates the registration just
before starting packet streaming.

6ea53391c0 ALSA: line6: variax: Rewrite complex timer & work combo with a delayed work
Variax driver had a very complex and staged startup sequence using
multiple timers and a work.  This patch simplifies the procedure to a
single delayed work.

Now the startup stage consists of:
- VARIAX_STARTUP_VERSIONREQ:
  requesting the version and the message handler raises up to the next
  stage upon receiving the reply.  The request is repeated until a
  reply arrives.
- VARIAX_STARTUP_ACTIVATE:
  does activation, and queue for the next stage.
- VARIAX_STARTUP_SETUP:
  registers the card.

0b074ab7fc ALSA: line6: Assure canceling delayed work at disconnection
The current code performs the cancel of a delayed work at the late
stage of disconnection procedure, which may lead to the access to the
already cleared state.

This patch assures to call cancel_delayed_work_sync() at the beginning
of the disconnection procedure for avoiding that race.  The delayed
work object is now assigned in the common line6 object instead of its
derivative, so that we can call cancel_delayed_work_sync().

Along with the change, the startup function is called via the new
callback instead.  This will make it easier to port other LINE6
drivers to use the delayed work for startup in later patches.

e4e07c6cdc ALSA: hdspm: Fix single speed ADAT capture and playback with RME HDSPe AIO
By taking into account the mapping from logical to DMA channels when
enabling or disabling audio channels, ADAT channels 3 to 8 on the RME
HDSPe AIO card are now correctly captured and played back in single speed
mode.

Since the mapping is an identity mapping for all cards except AIO and
RayDAT, only those cards should be affected by this patch. It was tested on
an AIO card. The patch needs testing on other cards, in particular RayDAT.

Note: this patch does not solve ADAT capture and playback issues in double
or triple speed mode. That seems to be another problem.

c4580f2097 ALSA: dice: add stream format parameters for PreSonus FireStudio
FireStudio was launched by PreSonus 2009. This model consists of three
ICs for its packet processing on IEEE 1394 bus:

 - Texus Instruments TSB41AB2 for physical layer of IEEE 1394 bus
 - WaveFront semiconductor, Dice II STD ASIC for link layer of IEEE 1394
   bus and protocol layer
 - Xilinx Spartan XG3S500E FPGA for signal processing

This model don't support TCAT extended application protocol. For such
devices, ALSA dice driver needs to have hard-coded parameters for stream
formats.

This commit adds hard-coded table for this model. As a result, sampling
transfer frequencies of 88.2/96.0 kHz are supported. I note that this
patch can be backported to Linux kernel v4.18 and later.
