05f254a636 ALSA: usb-audio: Improve filtering of sample rates on Focusrite devices
Previously we were filtering out only upper unsupported sampling rates.
This patch adds filtering of the lower unsupported sampling rates. As a
result there is 1:1 mapping between altsetting and supported rates.

The issue was found on a Scarlett 3rd Gen card (see linked bug), but the
same filtering is likely needed for the Scarlett 1st and 2nd Gen as well
as the older Clarett cards which lacks Valid Alternate Setting Control.

Patch was not tested on a real hardware.

d893d5eaab ALSA: usb-audio: Save UAC sample size information
Within the UAC descriptor, there is information describing the size of a
sample (bSubframeSize/bSubslotSize) and the number of relevant bits
(bBitResolution).  Currently, fmt_bits carries only the bit resolution,
however, some offloading entities may also require the overall size of the
sample.  Save this information in a separate parameter, as depending on the
UAC format type, the sample size can not easily be decoded from other
existing parameters.

b50a3e9844 sound: usb: format: don't warn that raw DSD is unsupported
UAC 2 & 3 DAC's set bit 31 of the format to signal support for a
RAW_DATA type, typically used for DSD playback.

This is correctly tested by (format & UAC*_FORMAT_TYPE_I_RAW_DATA),
fp->dsd_raw = true; and call snd_usb_interface_dsd_format_quirks(),
however a confusing and unnecessary message gets printed because
the bit is not properly tested in the last "unsupported" if test:
if (format & ~0x3F) { ... }

For example the output:

usb 7-1: new high-speed USB device number 5 using xhci_hcd
usb 7-1: New USB device found, idVendor=262a, idProduct=9302, bcdDevice=0.01
usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=6
usb 7-1: Product: TC44C
usb 7-1: Manufacturer: TC44C
usb 7-1: SerialNumber: 5000000001
hid-generic 0003:262A:9302.001E: No inputs registered, leaving
hid-generic 0003:262A:9302.001E: hidraw6: USB HID v1.00 Device [DDHIFI TC44C] on usb-0000:08:00.3-1/input0
usb 7-1: 2:4 : unsupported format bits 0x100000000

This last "unsupported format" is actually wrong: we know the
format is a RAW_DATA which we assume is DSD, so there is no need
to print the confusing message.

This we unset bit 31 of the format after recognizing it, to avoid
the message.

6aa8700150 ALSA: usb-audio: Support multiple control interfaces
Registering Numark Party Mix II fails with error 'bogus bTerminalLink 1'.
The problem stems from the driver not being able to find input/output
terminals required to configure audio streaming. The information about
those terminals is stored in AudioControl Interface. Numark device
contains 2 AudioControl Interfaces and the driver checks only one of them.

According to the USB standard, a device can have multiple audio functions,
each represented by Audio Interface Collection. Every audio function is
considered to be closed box and will contain unique AudioControl Interface
and zero or more AudioStreaming and MIDIStreaming Interfaces.

The Numark device adheres to the standard and defines two audio functions:
- MIDIStreaming function
- AudioStreaming function
It starts with MIDI function, followed by the audio function. The driver
saves the first AudioControl Interface in `snd_usb_audio` structure
associated with the entire device. It then attempts to use this interface
to query for terminals and clocks. However, this fails because the correct
information is stored in the second AudioControl Interface, defined in the
second Audio Interface Collection.

This patch introduces a structure holding association between each
MIDI/Audio Interface and its corresponding AudioControl Interface,
instead of relying on AudioControl Interface defined for the entire
device. This structure is populated during usb probing phase and leveraged
later when querying for terminals and when sending USB requests.

Alternative solutions considered include:
- defining a quirk for Numark where the order of interface is manually
changed, or terminals are hardcoded in the driver. This solution would
have fixed only this model, though it seems that device is USB compliant,
and it also seems that other devices from this company may be affected.
What's more, it looks like products from other manufacturers have similar
problems, i.e. Rane One DJ console
- keeping a list of all AudioControl Interfaces and querying all of them
to find required information. That would have solved my problem and have
low probability of breaking other devices, as we would always start with
the same logic of querying first AudioControl Interface. This solution
would not have followed the standard though.

This patch preserves the `snd_usb_audio.ctrl_intf` variable, which holds
the first AudioControl Interface, and uses it as a fallback when some
interfaces are not parsed correctly and lack an associated AudioControl
Interface, i.e., when configured via quirks.

Many devices with a single alternate setting do not have a Valid

fa4e7a6fa1 ALSA: usb-audio: Fix regression on detection of Roland VS-100
It's been reported that the recent kernel can't probe the PCM devices
on Roland VS-100 properly, and it turned out to be a regression by the
recent addition of the bit shift range check for the format bits.
In the old code, we just did bit-shift and it resulted in zero, which
is then corrected to the standard PCM format, while the new code
explicitly returns an error in such a case.

For addressing the regression, relax the check and fallback to the
standard PCM type (with the info output).

93db51d06b ALSA: usb-audio: Check valid altsetting at parsing rates for UAC2/3
The current driver code assumes blindly that all found sample rates for
the same endpoint from the UAC2 and UAC3 descriptors can be used no
matter which altsetting, but actually this was wrong: some devices
accept only limited sample rates in each altsetting.  For determining
which altsetting supports which rate, we need to verify each sample rate
and check the validity via UAC2_AS_VAL_ALT_SETTINGS.  This control
reports back the available altsettings as a bitmap.

This patch implements the missing piece above, the verification and
reconstructs the sample rate tables based on the result.

An open question is how to deal with the altsettings that ended up
with no valid sample rates after verification.  At least, there is a
device that showed this problem although the sample rates did work in
the later usage (see bug link).  For now, we accept such an altset as
is, assuming that it's a firmware bug.

devices already did.  The workaround is put in a unified helper
function, set_fixed_rate(), to be called from both places now.

6da2ec5605 treewide: kmalloc() -> kmalloc_array()
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:

        kmalloc(a * b, gfp)

with:
        kmalloc_array(a * b, gfp)

as well as handling cases of:

        kmalloc(a * b * c, gfp)

with:

        kmalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kmalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kmalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().

The Coccinelle script used for this was:

Recently released USB Audio Class 3.0 specification
introduces many significant changes comparing to
previous versions, like
 - new Power Domains, support for LPM/L1
 - new Cluster descriptor
 - changed layout of all class-specific descriptors
 - new High Capability descriptors
 - New class-specific String descriptors
 - new and removed units
 - additional sources for interrupts
 - removed Type II Audio Data Formats
 - ... and many other things (check spec)

It also provides backward compatibility through
multiple configurations, as well as requires
mandatory support for BADD (Basic Audio Device
Definition) on each ADC3.0 compliant device

This patch adds initial support of UAC3 specification
that is enough for Generic I/O Profile (BAOF, BAIF)
device support from BADD document.

6d1f2f6056 ALSA: usb-audio: Fix audio output on Roland SC-D70 sound module
Roland SC-D70 reports its device class as vendor specific class and
the quirk QUIRK_AUDIO_FIXED_ENDPOINT was used for audio output.

In the quirks table the sampling rate was hard-coded to 44100 Hz
and therefore not worked when the sound module was in 48000 Hz mode.

In this change the quirk is changed to QUIRK_AUDIO_STANDARD_INTERFACE
but as the sound module reports incorrect bSubframeSize in its
descriptors, additional change is made in format.c to detect it and
to override it (which uses the existing code for Edirol SD-90).

Tested both when the sound module was in 44100 Hz mode and 48000 Hz
mode and both audio input and output. MIDI related part of the driver
is not touched.

126825e7ea ALSA: snd-usb: add quirks handler for DSD streams
Unfortunately, none of the UAC standards provides a way to identify DSD
(Direct Stream Digital) formats. Hence, this patch adds a quirks
handler to identify USB interfaces that are capable of handling DSD.

That quirks handler can augment the already parsed formats bit-field,
by any of the new SNDRV_PCM_FMTBIT_DSD_{U8_U16} and setting the dsd_dop
flag in the audio format, if the driver should take care for the DOP
byte stuffing.

The only devices that are known to work with this are the ones with
a 'Playback Designs' vendor id.

06ffc1ebdd ALSA: usb-audio: UAC2: do clock validity check earlier
Move the check that parse_audio_format_rates_v2() do after
receiving the clock source entity ID directly into the find
function and add a validation flag to the function.

This patch does not introduce any logic flow change.

It is provided to allow introducing automatic clock switching
easier later. By moving this uac_clock_source_is_valid callsite,
2 additional callsites can be avoided.

This field may use up to 32 bits, so it should be handled as unsigned
int.
