| * ALSA: dice: restrict the driver to playback-only devicesClemens Ladisch2013-10-202-4/+15
| | | | | | | | | | | | | | | | At the moment, this driver supports only playback, while FFADO supports (only) full-duplex devices. So, prevent conflicts by not claiming devices that would be better handled by FFADO. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
| * ALSA: dice: fix detection of Weiss devicesClemens Ladisch2013-10-201-5/+12
| | | | | | | | | | | | | | | | While most DICE devices keep TCAT's default category ID of 0x04, Weiss devices identify themselves with 0x00. Reported-by: Rolf Anderegg <rolf.anderegg@weiss.ch> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

| * ALSA: dice: document quadlet alignmentClemens Ladisch2013-10-201-3/+3
| | | | | | | | | | | | | | | | Doing accesses without quadlet alignment is a bad idea because the firmware's byte-swapping would garble the data; clarify this in the documentation. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

| * ALSA: dice: remove 10s period length limitClemens Ladisch2013-10-201-1/+1
| | | | | | | | | | | | | | Since commit f2b3614cefb6 (Don't check DMA time-out too shortly), we need no longer to restrict the period length to less than 10 s. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
| * ALSA: dice: avoid superflous write at bus resetClemens Ladisch2013-10-201-0/+5
| | | | | | | | | | | | | | When a bus reset happens, the enable register is automatically cleared, so we do not need to clear it manually when stopping the stream. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
| * ALSA: firewire: extend snd_fw_transaction()Clemens Ladisch2013-10-208-206/+137
| | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
| * ALSA: dice: optimize reading of consecutive registersClemens Ladisch2013-10-201-16/+11

| * ALSA: dice: fix device detection for other vendorsClemens Ladisch2013-10-201-18/+84
| | | | | | | | | | | | | | | | | | DICE devices do not have a unique specifier ID in their unit directory (it's always the same as the device vendor's ID), so rely on just the version ID for driver loading, and use a heuristic in the probe callback to detect actual DICE devices.

| * ALSA: firewire: introduce amdtp_out_stream_running()Clemens Ladisch2013-10-204-23/+18
| | | | | | | | | | | | | | | | 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. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

| * ALSA: dice: fix hang when unplugging a running deviceClemens Ladisch2013-10-201-2/+5
| | | | | | | | | | | | | | | | | | | | | | When aborting a PCM stream, the xrun is signaled only if the stream is running. When disconnecting a PCM stream, calling snd_card_disconnect() too early would change the stream into a non-running state and thus prevent the xrun from being noticed by user space. To prevent this, move the snd_card_disconnect() call after the xrun. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
| * ALSA: dice, firewire-lib: add blocking modeClemens Ladisch2013-10-203-27/+36
| | | | | | | | | | | | | | | | | | Allow AMDTP output streams to use blocking mode. Use it for DICE devices, because the old DICE-II chip will in some cases not be able to lock to non-blocking streams (erratum E7). Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
| * ALSA: dice: reduce noisy loggingClemens Ladisch2013-10-201-2/+2

| * ALSA: dice: allow all sample ratesClemens Ladisch2013-10-201-13/+42
| | | | | | | | | | | | | | | | | | | | Instead of forcing a constant 44.1 kHz, read the current sample rate from the device when opening the PCM device. Actually changing the sample rate requires some separate controller application. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
| * ALSA: dice: optimize bus reset handlingClemens Ladisch2013-10-201-55/+93
| | | | | | | | | | | | | | After a bus reset, do not stop the stream completely to avoid having to reconfigure the device when restarting the stream. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
| * ALSA: add DICE driverClemens Ladisch2013-10-173-0/+1023
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As a start point for further development, this is an incomplete driver for DICE devices: - only playback (so no clock source except the bus clock) - only 44.1 kHz - no MIDI - recovery after bus reset is slow - hwdep device is created, but not actually implemented Contains compilation fixes by Stefan Richter.

This is especially useful to 1394 audio drivers for model-specific parameters and methods" * tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: remove support of fw_driver.driver.probe and .remove methods firewire: introduce fw_driver.probe and .remove methods
| * firewire: introduce fw_driver.probe and .remove methodsStefan Richter2013-06-093-107/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
