PCIe allows for MSI-X BAR to be either dedicated, or MSI-X Table may
be co-located in some functional BAR. In the later case xhci(4) is
unable to allocate active resource for the table because BAR is
already activated.
Handle it by checking for this special case, and not try to alloc
resource if MSI-X BAR is IO.

At least on Orange Pi PC Plus even the host mode does not work without
enabling the phy and setting it to the host mode.
The driver will now parse dr_mode property and will try to configure
itself and the phy accordingly.
OTG mode is not supported yet, so it is treated as the device / peripheral
mode.
The phy is enabled -- powered on -- only for the host mode.
The device mode requires support from a phy driver, e.g., aw_usbphy on
Allwinner platform.
aw_usbphy does not support the device mode, so it cannnot work yet.

The "Intel Sunrise Point-LP USB 3.0 controller" doesn't update the wMaxPacket
field in the control endpoint context automatically causing a BABBLE error code
on the initial first USB device descriptor read, when the bMaxPacketSize is not
8 bytes.

The AMD's Ryzen 3 3200g XHCI controllers apparently need the evaluate
control endpoint context command, but we don't need to issue this
command when the bMaxPacketSize is received after the read of the USB
device descriptor, because this part should be handled automatically.

The XHCI specification says that the XHCI controller should detect
reception of the USB device descriptors, and automatically update
the max packet size in the control endpoint context.

The newer hardware revisions of the Raspberry Pi 4 removed the ability of
the VIA VL805 xhci controller to load its own firmware. Instead the
firmware must be installed at the appropriate time by the VideoCore
coprocessor.

Create an acpi attachment for the DWC USB OTG device. This is present in
the Raspberry Pi 4 in the USB-C port normally used to power the board. Some
firmware presents the kernel with ACPI tables rather than FDT so we need
an ACPI attachment.

Name each ehci driver uniquely.
This remove the warning printed at each arm boot :
module_register: cannot register simplebus/ehci from kernel; already loaded from kernel
A similar fix was done in r333074 but imx_ehci wasn't renamed and generic_ehci wasn't
present at that time.
because it clobbers the super speed link status when a device is in super
speed mode. Currently the power bit is not needed for anything in the USB
hub driver.
This fixes USB warm reset for super speed devices.

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked). Use it in
preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and

The newer versions of RPi FDT flipped the order of the interrupts
specification and added an 'interrupt-names' property for driver aide in
finding the correct interrupt, rather than assuming the positions. Use it if
it's available, or fallback to the old method if there is no interrupt-names
property with a usb value.
This has been tested with both old RPi3B FDT and new RPi3B FDT, USB again
works on the latter.

Do not configure any endpoint twice, but instead keep track of which
endpoints are configured on a per device basis, and use an evaluate
endpoint context command instead. When changing the configuration make
sure all endpoints get deconfigured and the configured endpoint mask
is reset.
This fixes an issue where an endpoint might stop working if there is
an error and the endpoint needs to be reconfigured as a part of the
error recovery mechanism in the FreeBSD USB stack.

above 1Kbyte. It might look like some XHCI(4) controllers do not
support when the USB control transfer is split using a link TRB. The
next NORMAL TRB after the link TRB is simply failing with XHCI error
code 4. The quirk ensures we allocate a 64Kbyte buffer so that the
data stage TRB is not broken with a link TRB.

Marvell XHCI is in fact generic-xhci, so move the driver and
add the compatible string.
While here, get and enable the phy if the dtb provide one.
The xhci bindings state that phys should be in a 'phys' property but
Marvell DTS uses 'usb-phy', only add support for 'usb-phy' for now.
