We try to avoid to create and look up parent domain hierarchy, which is
a normal way we need because it's indeed is a hierarchy. Instead we set
affinity via parent irq by using irq_set_affinity API.

Fix the videobuf2-rdma-sg to videobuf2-cma-sg, and move it into
videobuf2 directory.
The videobuf2-cma-sg almost keep same as videobuf2-rdma-sg, both of them

support the videobuf2-dma-sg if the device's attr without force

Add a new instance for rockchip pinctrl to do selftest, and the userland
can set or get the iomux to one pin directly.
Build the iomux by gcc:
xx-gcc tools/testing/selftests/rkpinctrl/iomux.c -o iomux
Tested on rk3588-evb1:
[root@RK3588:/]# iomux 1 15 1
[root@RK3588:/]# iomux 1 15
mux get (GPIO1-15) = 1
[root@RK3588:/]# iomux 1 15 2
[root@RK3588:/]# iomux 1 15
mux get (GPIO1-15) = 2

According to the spec "USB Interface Association Descriptor Device
Class Code and Use Model"[1], the Interface Association Descriptor
(IAD) is needed for composite device which has multiple interfaces
controlled independently of each other. Without the IAD, the device
may not work as expected because the USB system software will not
properly bind the interfaces with drivers (e.g UAC1 && UVC composite
device not recognized in Win10).

1. Use MPP_CMD_POLL_HW_IRQ to handle the hw slice irq.
Old MPP_CMD_POLL_HW_FINISH will wait hardware finish and skip hw irq.
2. Clear poll request msgs when it is handled.
NOTE: When MPP_CMD_POLL_HW_IRQ return slice with zero length the
current task is completed. This way can reduce an extra
MPP_CMD_POLL_HW_FINISH ioctl.

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.

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.
