      ALSA: oxfw: fix for Stanton SCS.1d · 41dbc792
      Takashi Sakamoto authored 
      Stanton SCS.1d uses Oxford Semiconductor FW 971 ASIC (FW971) for
communication. Although the unit is bound to ALSA oxfw driver, the instance
of sound card can not be added due to its quirk of plug information. This
bug was added when snd-scs1x is merged into snd-oxfw at commit
9e2004f9 ("ALSA: oxfw: obsolete scs1x module").

This commit fixes the driver for the quirk. In cases that the unit returns
NOT IMPLEMENTED for some AV/C commands, the sound card is added without any
PCM/MIDI interfaces for packet streaming. For SCS.1d, model dependent
operation adds MIDI interface and applications can use it to operate
according to HSS1394 protocol from reverse-engineering work by Sean M.
Pappalardo.

Plug Control Register (PCR) has information that the unit has a pair of
plugs for isochronous communication:

(oMPR)
$ ./firewire-request /dev/fw1 read 0xfffff0000900
result: 80ff0001
(iMPR)
$ ./firewire-request /dev/fw1 read 0xfffff0000980
result: 80ff0001

AV/C PLUG INFO also returns information that the unit has a pair of
plugs for isochronous communication.

(AV/C PLUG INFO command)
$ ./firewire-request /dev/fw1 fcp 0x01ff0200ffffffff
response: 000: 0c ff 02 00 01 01 02 02

However, AV/C PLUG SIGNAL INFO command is rejected for both plugs.

(AV/C OUTPUT PLUG SIGNAL INFO command)
$ ./firewire-request /dev/fw1 fcp 0x01ff1800ffffffff
response: 000: 0a ff 18 00 ff ff ff ff
(AV/C INPUT PLUG SIGNAL INFO command)
$ ./firewire-request /dev/fw1 fcp 0x01ff1900ffffffff
response: 000: 0a ff 19 00 ff ff ff ff

Furthermore, AV/C EXTENDED STREAM FORMAT INFO is not implemented.

(AV/C EXTENDED STREAM FORMAT INFO list subfunction for input plug)
$ ./firewire-request /dev/fw1 fcp 0x01ffbfc000000000ffff00ff
response: 000: 08 ff bf c0 00 00 00 00 ff ff 00 ff
(AV/C EXTENDED STREAM FORMAT INFO list subfunction for output plug)
$ ./firewire-request /dev/fw1 fcp 0x01ffbfc001000000ffff00ff
response: 000: 08 ff bf c0 01 00 00 00 ff ff 00 ff
(AV/C EXTENDED STREAM FORMAT INFO single subfunction for input plug)
$ ./firewire-request /dev/fw1 fcp 0x01ffbfc100000000ffffffff
response: 000: 08 ff bf c1 00 00 00 00 ff ff ff ff
(AV/C EXTENDED STREAM FORMAT INFO single subfunction for output plug)
$ ./firewire-request /dev/fw1 fcp 0x01ffbfc101000000ffffffff
response: 000: 08 ff bf c1 01 00 00 00 ff ff ff ff

      ALSA: oxfw: don't add MIDI/PCM interface when packet streaming is unavailable · 06a42a74
      Takashi Sakamoto authored 
      Stanton SCS.1d doesn't support packet streaming even if it has plugs for
isochronous communication.

This commit is a preparation for this case. The 'has_input' member is
added to specific structure, and MIDI/PCM interfaces are not added when
the member is false.

      ALSA: oxfw: use ENXIO for not-supported cases · 03be63b2
      Takashi Sakamoto authored 
      When AV/C command returns 'NOT IMPLEMENTED' status in its response, ALSA
oxfw driver uses ENOSYS as error code. However, it's expected just to be
used for missing system call number.

This commit replaces it with ENXIO.

      ALSA: hda: Rename back to dmic_detect option · 7fba6aea
      Takashi Iwai authored 
      We've got quite a few bug reports showing the SOF driver being loaded
unintentionally recently, and the reason seems to be that users didn't
know the module option change: with the recent kernel, a new option
dsp_driver=1 has to be passed to a new module snd-intel-dspcfg
instead of snd_hda_intel.dmic_detect=0 option.

That is, actually there are two tricky things here:
- We changed the whole detection in another module and another
  option semantics.
- The existing option for skipping the DSP probe was also renamed.

For avoiding the confusion and giving user more hint, this patch
reverts the renamed option dsp_driver back to dmic_detect for
snd-hda-intel module, and show the warning about the module option
change when the non-default value is passed.

Fixes: 82d9d54a ("ALSA: hda: add Intel DSP configuration / probe code")
