[ Upstream commit 23b5f73266e59a598c1e5dd435d87651b5a7626b ]

During HARD_RESET the data link is disconnected.
For self powered device, the spec is advising against doing that.

&gt;From USB_PD_R3_0
7.1.5 Response to Hard Resets
Device operation during and after a Hard Reset is defined as follows:
Self-powered devices Should Not disconnect from USB during a Hard Reset
(see Section 9.1.2).
Bus powered devices will disconnect from USB during a Hard Reset due to the
loss of their power source.

Tackle this by letting TCPM know whether the device is self or bus powered.

This overcomes unnecessary port disconnections from hard reset.
Also, speeds up the enumeration time when connected to Type-A ports.

<title>USB: Wait for extra delay time after USB_PORT_FEAT_RESET for quirky hub</title>

Devices connected under Terminus Technology Inc. Hub (1a40:0101) may
fail to work after the system resumes from suspend:
[  206.063325] usb 3-2.4: reset full-speed USB device number 4 using xhci_hcd
[  206.143691] usb 3-2.4: device descriptor read/64, error -32
[  206.351671] usb 3-2.4: device descriptor read/64, error -32

Info for this hub:
T:  Bus=03 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=480 MxCh= 4
D:  Ver= 2.00 Cls=09(hub  ) Sub=00 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=1a40 ProdID=0101 Rev=01.11
S:  Product=USB 2.0 Hub

I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub

Some expirements indicate that the USB devices connected to the hub are
innocent, it's the hub itself is to blame. The hub needs extra delay
time after it resets its port.

Hence wait for extra delay, if the device is connected to this quirky
hub.

add such methods for usb_serial_driver, provide tty_operations
-&gt;[sg]et_serial() calling those.  For now the lack of methods
in driver means ENOIOCTLCMD from usb-serial -&gt;[sg]et_serial(),
making tty_ioctl() fall back to calling -&gt;ioctl().  Once all
drivers are converted, we'll be returning -ENOTTY instead,
completing the switchover.

<content type='text'>
The driver_info field that is used for describing each of the usb-net
drivers using the usbnet.c core all declare their information as const
and the usbnet.c itself does not try and modify the struct.

It is therefore a good idea to make this const in the usbnet.c structure
in case anyone tries to modify it.

<content type='text'>
Some hardware implementations require to configure pins differently
according to the USB role (host/device), this can be an update of the
pins routing or a simple GPIO value change.

This patch introduces new optional "host" and "device" pinctrls.
If these pinctrls are defined by the device, they are respectively
selected on host/device role start.

If a default pinctrl exist, it is restored on host/device role stop.

Thee USB Audio Class 3 (UAC3) introduces Power Domains as a new
feature to let a host turn individual parts of an audio function
to different power states via USB requests. This lets the device
get to know a bit amore about what the host is up to in order to
optimize power consumption efficiently.

The Power Domains are optional for UAC3 configuration but all
UAC3 devices shall include at least one BADD configuration where
the support for Power Domains is compulsory.

This patch adds a set of features/helpers to parse these power
domains and change their status.

<content type='text'>
This patch adds support for the Processig Units defined in
the UAC3 spec. The main difference with the previous specs
is the lack of on/off switches in the controls for these
units and the addiction of the new Multi Function Processing
Unit.

The current version of the UAC3 spec doesn't define any
useful controls for the new Multi Function Processing Unit
so no control will get created once this unit is parsed.
