Allow setting configfs params p_hs_bint/c_hs_bint to 0. If they are set
to 0, determine the largest bInterval (4 to 1) for which the required
bandwidth of the max samplerate fits the max allowed packet size. If the
required bandwidth exceeds max bandwidth for single-packet mode
(ep->mc=1), keep bInterval at 1.
The FS speed is left at fixed bInterval=1.
If for any speed the required bandwidth exceeds the max bandwidth
corresponding to the selected/determined bInterval, print a warning.

When USB cable gets disconnected, the undergoing playback/capture
stalls, without any notification to u_audio about the change.
Experiments with a dwc2 gadget revealed that Suspend interrupt is
thrown at cable disconnection, which the gadget framework translates to
calling suspend callback of a function, if it is defined.
Add the suspend callback to f_uac2 function, calling
corresponding method of u_audio in order to stop the respective PCM
streams and to notify subscribed clients at cable disconnection.

(cherry picked from commit 7ff4a3b548https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git usb-next)
The Playback/Capture ctl currently reports rate value set by USB
control selector UAC2_CS_CONTROL_SAM_FREQ (fixed for UAC1). When the
stops playback/capture, the reported value does not change. The gadget
side has no information whether the host has started/stopped
capture/playback.
This patch sets the value reported by the respective rate ctl to zero
when the host side has stopped playback/capture. Also, it calls
snd_ctl_notify when start/stop occurs, so that a subscribed client can
act appropriately.
Tests have confirmed that USB hosts change UAC2_CS_CONTROL_SAM_FREQ
before switching altsetting to activate playback/capture, resulting in
correct order (params->c/p_srate is set to requested rate before
u_audio_start_capture/playback is called).
The gadget rate notifications are used by user-space audio gadget
controller gaudio_ctl https://github.com/pavhofman/gaudio_ctl.

(cherry picked from commit 8fe9a03f43https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git usb-next)
A list of sampling rates can be specified via configfs. All enabled
sampling rates are sent to the USB host on request. When the host
selects a sampling rate, the internal active rate (stored in
struct f_uac2) is updated.
The gadget no longer supports only one frequency. Therefore USB strings
corresponding to the clock sources are renamed from specific Hz value to
general names Input clock/Output clock.
Config strings with single value stay compatible with the previous
version.
Multiple samplerates passed as configuration arrays to g_audio module
when built for f_uac2.

If bInterval is 1, then p_interval is 8000 and p_interval_mil is 8E9,
which is too big for a 32-bit value. While the storage is indeed
64-bit, this value is used as the divisor in do_div() which will
truncate it into a uint32_t leading to incorrect calculated values.
Switch back to keeping the base value in struct snd_uac_chip which fits
easily into an int, meaning that the division can be done in two steps
with the divisor fitting safely into a uint32_t on both steps.

(cherry picked from commit f2f69bf65d)
The u_audio param fb_max was not set to its default value in f_uac1.c.
As a result the maximum value of Playback Pitch ctl was kept at 1000000,
not allowing to set faster playback pitch for UAC1.
The setting required moving the default constant UAC2_DEF_FB_MAX from
u_uac2.h to FBACK_FAST_MAX in u_audio.h as that header is common for
f_uac1.c and f_uac2.c.

(cherry picked from commit d9f2734843)
EP IN is hard-coded as ASYNC both in f_uac1 and f_uac2 but u_audio sends
steady number of audio frames in each USB packet, without any control.
This patch adds 'Playback Pitch 1000000' ctl analogous to the existing
'Capture Pitch 1000000' ctl. The calculation of playback req->length in
u_audio_iso_complete respects the Playback Pitch ctl value to 1ppm now.
Max. value for Playback Pitch is configured by the existing parameter
uac2_opts->fb_max, used also for the Capture Pitch.
Since the EP IN packet size can be increased by uac2_opts->fb_max now,
maxPacketSize for the playback direction is calculated by the same
algorithm as for the async capture direction in
f_uac2.c:set_ep_max_packet_size.

USB Audio Class 1/2 have ability to change device's
volume and mute by USB Host through class-specific control
requests. Device also can notify Host about volume/mute
change on its side through optional interrupt endpoint.
This patch adds Volume and Mute ALSA controls which can be
used by user to send and receive notifications to/from
the USB Host about Volume and Mute change.
These params come from f_uac* so volume and mute controls
will be created only if the function support and enable
each explicitly
