[PATCH 00/15] ALSA: usb-audio: Introduce and convert to quirk_flags

[PATCH 00/15] ALSA: usb-audio: Introduce and convert to quirk_flags

[Takashi Iwai]

As more and more device-specific workarounds came up and gathered in
various places, it becomes harder to manage.  Now it's time to clean
up and collect workarounds more consistently and make them more easily
applicable.

This patch set introduces a new bitmap flags, quirk_flags, to contain
various device-specific quirks.  Those are separate one from the
quirks in quirks-table.h; the quirks-table.h entries are for more
intrusive stuff that needs the descriptor override, while the new
quirk_flags is for easier ones that are tied with the vendor:product
IDs.

[PATCH 01/15] ALSA: usb-audio: Introduce quirk_flags field

[Takashi Iwai]

As more and more device-specific workarounds came up and gathered in
various places, it becomes harder to manage.  Now it's time to clean
up and collect workarounds more consistently and make them more easily
applicable.

This patch is the first step for that: a new field quirk_flags is
introduced in snd_usb_audio struct to contain the bit flags for
various device-specific quirks.  Those are separate one from the
quirks in quirks-table.h; the quirks-table.h entries are for more
intrusive stuff that needs the descriptor override, while the new
quirk_flags is for easier ones that are tied with the vendor:product
IDs.

In this patch, as the first example, we convert the list of devices
and vendors to ignore GET_SAMPLE_RATE, formerly defined in
snb_usb_get_sample_rate_quirk().

[PATCH 02/15] ALSA: usb-audio: Move media-controller API quirk into quirk_flags

[Takashi Iwai]

The devices that can have media-controller API entries are currently
specified via tables in quirks-table.h, as a part of descriptor
override.  This can fit better to the new quirk_flags, as we just need
a matching with the given ID and create the MC entries accordingly.

[PATCH 03/15] ALSA: usb-audio: Move txfr_quirk handling to quirk_flags

[Takashi Iwai]

The txfr_quirk field was meant for aligning the transfer, and it's set
for certain devices in quirks-table.h.  Now we can move that stuff
also to the new quirk_flags gracefully, and reduce the quirks-table.h
entries (that are exposed to module device table).

As the quirks-table.h entries are also with the name string override,
provide the corresponding entries to the usb_audio_names[] table,
too.

[PATCH 04/15] ALSA: usb-audio: Move tx_length quirk handling to quirk_flags

[Takashi Iwai]

There is another quirk for the transfer, and that's currently specific
to Zoom R16/24, handled in create_standard_audio_quirk().  Let's move
this also to the new quirk_flags.

[PATCH 06/15] ALSA: usb-audio: Move clock setup quirk into quirk_flags

[Takashi Iwai]

There are a couple of device-specific quirks in the clock setup code,
and those can be moved gracefully to quirk_flags, too.

[PATCH 08/15] ALSA: usb-audio: Move control message delay quirk into quirk_flags

[Takashi Iwai]

We apply some delay for the control messages on certain devices as a
workaround, and this can be moved into the quirk_flags as well.
Currently there are three different delay periods (1ms, 5ms and 20ms),
so three different quirk bits are assigned for them.

[PATCH 09/15] ALSA: usb-audio: Move interface setup delay into quirk_flags

[Takashi Iwai]

Yet another delay is applied at switching the interface.  This can be
moved to quirk_flags, too.

[PATCH 10/15] ALSA: usb-audio: Move rate validation quirk into quirk_flags

[Takashi Iwai]

The rate validation at the device probe is applied only to the
specific devices (currently only for MOTU devices), and this check can
be moved to quirk_flags gracefully, too.

[PATCH 12/15] ALSA: usb-audio: Move ignore_ctl_error check into quirk_flags

[Takashi Iwai]

The mixer code has a flag ignore_ctl_error for ignoring the errors
returned from the device wrt mixer accesses, and this is set from the
entries in mixer_maps.c, as well as ignore_ctl_error module option.
Those can be well integrated into the new quirk_flags field, too.

[PATCH 13/15] ALSA: usb-audio: Move generic DSD raw detection into quirk_flags

[Takashi Iwai]

The generic DSD raw detection is based on the known allow list, and we
can integrate it into quirk_flags, too.

[PATCH 14/15] ALSA: usb-audio: Add quirk_flags module option

[Takashi Iwai]

This patch adds a new module option, quirk_flags, for allowing user to
try some additional device-specific quirk behavior more easily.
When this option is set to non-zero, it overrides the quirk_flags, and
the specific workaround is applied.
