ALSA: firewire: extend snd_fw_transaction()

2013-10-20T20:07:57+00:00

Add a flag to snd_fw_transaction() to allow it to abort when a bus reset
happens.  This removes most of the duplicated error handling loops that
were required around calls to the low-level fw_run_transaction().

Also add a flag to suppress error messages; errors are expected when we
attempt to clean up after the device was unplugged.

ALSA: dice: support dual-wire stream format at 192 kHz

2013-10-20T20:07:57+00:00

Change the AMDTP streaming code to handle the non-standard stream format
that DICE devices use at sample rates greater than 96 kHz.

ALSA: firewire: introduce amdtp_out_stream_running()

2013-10-20T20:07:57+00:00

Introduce the helper function amdtp_out_stream_running().  This makes
many checks in amdtp.c clearer and frees the device drivers from having
to track this with a separate variable.

ALSA: firewire-speakers: remove not-reused member from structure

2013-07-10T15:50:58+00:00

"pcm" member in struct fwspk is used to set pcm operations but is not used
again. This commit remove this member and set pcm operations with
snd_pcm_set_ops().

firewire: introduce fw_driver.probe and .remove methods

2013-06-09T16:15:00+00:00

FireWire upper layer drivers are converted from generic
    struct driver.probe() and .remove()
to bus-specific
    struct fw_driver.probe() and .remove().

The new .probe() adds a const struct ieee1394_device_id *id argument,
indicating the entry in the driver's device identifiers table which
matched the fw_unit to be probed.  This new argument is used by the
snd-firewire-speakers driver to look up device-specific parameters and
methods.  There is at least one other FireWire audio driver currently in
development in which this will be useful too.

The new .remove() drops the unused error return code.

Although all in-tree drivers are being converted to the new methods,
support for the old methods is left in place in this commit.  This
allows public developer trees to merge this commit and then move to the
new fw_driver methods.

ALSA: firewire-speakers: remove __dev* attributes

2012-12-07T06:29:30+00:00

CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Merge tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394

2012-03-23T03:31:15+00:00

Pull IEEE 1394 (FireWire) subsystem updates post v3.3 from Stefan Richter:

 - Some SBP-2 initiator fixes, side product from ongoing work on a target.

 - Reintroduction of an isochronous I/O feature of the older ieee1394 driver
   stack (flush buffer completions); it was evidently rarely used but not
   actually unused.  Matching libraw1394 code is already available.

 - Be sure to prefix all kernel log messages with device name or card name,
   and other logging related cleanups.

 - Misc other small cleanups, among them a small API change that affects
   sound/firewire/ too. Clemens Ladisch is aware of it.

firewire: move fw_device reference counting from drivers to core

2012-01-15T17:37:20+00:00

fw_unit device drivers invariably need to talk to the fw_unit's parent
(an fw_device) and grandparent (an fw_card).  firewire-core already
maintains an fw_card reference for the entire lifetime of an fw_device.
Likewise, let firewire-core maintain an fw_device reference for the
entire lifetime of an fw_unit so that fw_unit drivers don't have to.
