The arg_count parameter to syscon_regmap_lookup_by_phandle_args()

Set FLAG_WWAN instead of FLAG_ETHERNET for RNDIS interfaces on Mobile
Broadband Modems, as opposed to regular Ethernet adapters.
Otherwise NetworkManager gets confused, misjudges the device type,
and wouldn't know it should connect a modem to get the device to work.
What would be the result depends on ModemManager version -- older
ModemManager would end up disconnecting a device after an unsuccessful
probe attempt (if it connected without needing to unlock a SIM), while
a newer one might spawn a separate PPP connection over a tty interface
instead, resulting in a general confusion and no end of chaos.
The only way to get this work reliably is to fix the device type
and have good enough version ModemManager (or equivalent).

This is mainly set of cleanups of asm-generic/io.h, resolving problems
with inconsistent semantics of ioread64/iowrite64 that were causing
runtime and build issues.
The "GENERIC_IOMAP" version that switches between inb()/outb() and
readb()/writeb() style accessors is now only used on architectures that
have PC-style ISA devices that are not memory mapped (x86, uml, m68k-q40
and powerpc-powernv), while alpha and parisc use a more complicated
variant and everything else just maps the ioread interfaces to plan MMIO
(readb/writeb etc).
In addition there are two small changes from Raag Jadav to simplify
the asm-generic/io.h indirect inclusions and from Jann Horn to fix
a corner case with read_word_at_a_time.

There is new support for additional on-chip devices on Apple, Mediatek,
Renesas, Rockchip, Samsung, Google, TI, ST, Nvidia and Amlogic devices.
The Arm Morello reference platform gets a devicetree for booting in
normal aarch64 mode. The hardware supports experimental CHERI support,
which requires a modified kernel.
The AMD (formerly Xilinx) Versal NET SoC gets added, this is a combined
FPGA with Cortex-A78 CPUs in a SoC.
Six new ST STM32MP2 SoC variants are added. Like the earlier STM32MP25,
the MP211, MP213, MP215, MP231, MP233 and MP235 models are based on one
or two Cortex-A35 cores but each feature a different set of I/O devices.
Mediatek MT8370 is a minor variation of MT8390 with fewer CPU and
GPU cores
Apple T2 is the baseboard management controller on earlier Intel CPU
based Macs, with 16 models now gaining initial support.
All the above come with dts files for the reference boards. In
addition, these boards are added for the SoCs that are already supported.
- The Milk-V Jupiter board based on SpacemiT K1/M1
- NetCube Systems Kumquat board based on the 32-bit Allwinner V3s SoC
- Three boards based on 32-bit stm32mp1
- 11 distinct board variants from Toradex and one from Variscite,
all based on i.MX6

Lazy flushing of TPM auth sessions can interact badly with IMA + kexec,
resulting in loaded session handles being leaked across the kexec and
not cleaned up. Fix by ensuring any active auth session is ended before
the TPM is told about the shutdown, matching what is done when
suspending.

Some Infineon devices have a issue where the status register will get
stuck with a quick REQUEST_USE / COMMAND_READY sequence. This is not
simply a matter of requiring a longer timeout; the work around is to
retry the command submission. Add appropriate logic to do this in the
send path.
This is fixed in later firmware revisions, but those are not always
available, and cannot generally be easily updated from outside a
firmware environment.
Testing has been performed with a simple repeated loop of doing a
TPM2_CC_GET_CAPABILITY for TPM_CAP_PROP_MANUFACTURER using the Go code
at:
https://the.earth.li/~noodles/tpm-stuff/timeout-reproducer-simple.go

The change to only use interrupts to handle supported status changes
introduced an issue when it is necessary to poll for the status. Rather
than checking for the status after sleeping the code now sleeps after
the check. This means a correct, but slower, status change on the part
of the TPM can be missed, resulting in a spurious timeout error,
especially on a more loaded system. Switch back to sleeping *then*
checking. An up front check of the status has been done at the start of
the function, so this does not cause an additional delay when the status
is already what we're looking for.

TPM2 sessions have been flushed lazily since commit df745e2509 ("tpm:
Lazily flush the auth session"). If /dev/tpm{rm}0 is not accessed
in-between two in-kernel calls, it is possible that a TPM2 session is
re-started before the previous one has been completed.
This causes a spurios warning in a legit run-time condition, which is also
correctly addressed with a fast return path:

Lazy flushing of TPM auth sessions was introduced to speed up IMA
measurments into the TPM. Make use of it in tpm2_get_random as well,
which has the added benefit of not needlessly cleaning up the session
that IMA is using when there are no userspace accesses taking place.

Change the scope of the migrate subsystem to be dev managed instead of
drm managed.
The parent pci struct &device, that the xe struct &drm_device is a part
of, gets removed when a hot unplug is triggered, which causes the
underlying iommu group to get destroyed as well.
The migrate subsystem, which handles the lifetime of the page-table tree
(pt) BO, doesn't get a chance to keep the BO back during the hot unplug,
as all the references to DRM haven't been put back.
When all the references to DRM are indeed put back later, the migrate
subsystem tries to put back the pt BO. Since the underlying iommu group
has been already destroyed, a kernel NULL ptr dereference takes place
while attempting to keep back the pt BO.
