Pull ARM SoC boardfile updates from Arnd Bergmann
"Unused boardfile removal for 6.3
This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate
subsystem trees, but the majority is in the same branch, in order to
better handle dependencies between the patches and avoid breaking
bisection.
Unfortunately that leads to merge conflicts against other changes in
the subsystem trees, but they should all be trivial to resolve by
removing the files.
See commit 7d0d3fa733 ("Merge tag 'arm-boardfiles-6.0' of
git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
description of which machines were marked unused and are now removed.
The only removals that got postponed are Terastation WXL (mv78xx0) and
Jornada720 (StrongARM1100), which turned out to still have potential
users"

xHC supports several interrupters, each with its own mmio register set,
event ring and MSI/MSI-X vector. Transfers can be assigned different
interrupters when queued. See xhci 4.17 for details.
Current driver only supports one interrupter.
Create a xhci_interrupter structure containing an event ring, pointer to
mmio registers for this interrupter, variables to store registers over s3
suspend, erst, etc. Add functions to create and free an interrupter, and
pass an interrupter pointer to functions that deal with events.
Secondary interrupters are also useful without having an interrupt vector.
One use case is the xHCI audio sideband offloading where a DSP can take
care of specific audio endpoints.
When all transfer events of an offloaded endpoint can be mapped to a
separate interrupter event ring the DSP can poll this ring, and we can mask
these events preventing waking up the CPU.
Only minor functional changes such as clearing some of the interrupter
registers when freeing the interrupter.
Still create only one primary interrupter.

xHC controller can supports up to 1024 interrupters.
To fit these change the max_interrupters varable from u8 to u16.
Add a separate mask for the reserve and preserve bits [5:0] in the erst
base register and use it instead of the ERST_PRT_MASK.
ERSR_PTR_MASK [3:0] is intended for masking bits in the
event ring dequeue pointer register.

The USB_XHCI_RZV2M and USB_RENESAS_USB3 select other drivers

ERROR: modpost: "rzv2m_usb3drd_reset" [drivers/usb/host/xhci-plat-hcd.ko] undefined!
The xhci-rcar driver has a reverse dependency with the xhci core, and it
depends on the UDC driver in turn. To untangle this, make the xhci-rcar.ko
driver a standalone module that just calls into the xhci-plat.ko module
like other drivers do.
This allows handling the dependency on the USB_RZV2M_USB3DRD driver to
only affect the xhci-rcar module and simplify the xhci-plat module.
It also allows leaving out the hacks for broken dma mask and nested
devices from the rcar side and keep that only in the generic xhci driver.
As a future cleanup, the marvell and dwc3 specific bits of xhci-plat.c
could be moved out as well, but that is not required for this bugfix.

A USB peripheral can respond with a NAK if it is not yet ready to
send/receive data. In this case, the transaction should be retried. The
MAX3421 driver did do this, and switched to a different type of retry
after a number of 'fast' retries. On at least some USB flash devices,
this second type of retry never succeeds. This patch changes the
behaviour so that 'fast' retries continue.

xhci: Detect lpm incapable xHC USB3 roothub ports from ACPI tables
...
USB3 ports on xHC hosts may have retimers that cause too long
exit latency to work with native USB3 U1/U2 link power management states.
For now only use usb_acpi_port_lpm_incapable() to evaluate if port lpm
should be disabled while setting up the USB3 roothub.
Other ways to identify lpm incapable ports can be added here later if
ACPI _DSM does not exist.
Limit this to Intel hosts for now, this is to my knowledge only
an Intel issue.

One USB3 roothub port may support link power management, while another
root port on the same xHC can't due to different retimers used for
the ports.
This is the case with Intel Alder Lake, and possible future platforms
where retimers used for USB4 ports cause too long exit latecy to
enable native USB3 lpm U1 and U2 states.
Add a flag in the xhci port structure to indicate if the port is
lpm_incapable, and check it while calculating exit latency.

Allow PCI hosts to check and tune roothub and port settings
before the hub is up and running.
This override is needed to turn off U1 and U2 LPM for some ports
based on per port ACPI _DSM, _UPC, or possibly vendor specific mmio
values for Intel xHC hosts.
Usb core calls the host update_hub_device once it creates a hub.
Entering U1 or U2 link power save state on ports with this limitation
will cause link to fail, turning the usb device unusable in that setup.

Make sure xhci_free_dev() and xhci_kill_endpoint_urbs() do not race
and cause null pointer dereference when host suddenly dies.
Usb core may call xhci_free_dev() which frees the xhci->devs[slot_id]
virt device at the same time that xhci_kill_endpoint_urbs() tries to
loop through all the device's endpoints, checking if there are any
cancelled urbs left to give back.

When the host controller is not responding, all URBs queued to all
endpoints need to be killed. This can cause a kernel panic if we
dereference an invalid endpoint.
Fix this by using xhci_get_virt_ep() helper to find the endpoint and
checking if the endpoint is valid before dereferencing it.
