2015-01-20ALSA: line6: Drop invalid SNDRV_PCM_INFO_RESUME flagTakashi Iwai5-26/+0
The line6 drivers don't support the full resume although they set SNDRV_PCM_INFO_RESUME. These flags have to be dropped to inform properly to the user-space. Also, drop the CONFIG_PM in trigger callbacks, too, which are rather superfluous. Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-20ALSA: line6: Drop superfluous snd_device for rawmidiTakashi Iwai1-42/+23
Like the previous fix for PCM, attach the card-specific resource into rawmidi->private_data instead of handling in a snd_device object. This simplifies the code and structure. Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-20ALSA: line6: Drop superfluous snd_device for PCMTakashi Iwai1-34/+19
Instead of handling the card-specific resource in snd_device, attach it into pcm->private_data and release it directly in private_free. This simplifies the code and structure. Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-20ALSA: line6: Handle impulse response via control APITakashi Iwai5-124/+75
Instead of sysfs and the conditional build with Kconfig, implement the handling of the impulse response controls via control API, and always enable the build. Two new controls, "Impulse Response Volume" and "Impulse Response Period" are added as a replacement for the former sysfs files.

2015-01-20ALSA: line6: Split to each driverTakashi Iwai17-726/+747
Split to each individual driver for POD, PODHD, TonePort and Variax with a core LINE6 helper module. The new modules follow the standard ALSA naming rule with snd prefix: snd-usb-pod, snd-usb-podhd, snd-usb-toneport and snd-usb-variax, together with the corresponding CONFIG_SND_USB_* Kconfig items.

2015-01-19ALSA: line6: Use setup_timer() and mod_timer()Takashi Iwai2-7/+4
No functional change, refactoring with the standard helpers. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-12ALSA: move line6 usb driver into sound/usbTakashi Iwai26-0/+5776
Promote line6 driver from staging to sound/usb/line6 directory, and maintain through sound subsystem tree. This commit just moves the code and adapts Makefile / Kconfig. The further renames and misc cleanups will follow. Signed-off-by: Takashi Iwai <tiwai@suse.de>
