Tegra20 requires a slightly different interrupt handler than Tegra30 and
later, so parameterize the handler, so that each SoC implementation can
provide its own.

The current per-SoC setup code runs at a fairly arbitrary point during
probe, thereby making it less flexible for other SoC generations. Move
the call around slightly (after only the very basic, common setup that
applies to all SoC generations has been performed), which will allow
it to be used for other implementations.

Continuing the scheme of unification, push suspend/resume callbacks into
per-SoC driver so that they can be properly parameterized.

Subsequent patches will introduce further callbacks, so create a new
struct tegra_mc_ops to collect all of them in a single place. Move the
existing ->init() callback into the new structure.

As another step towards unifying both the Tegra210 (and earlier) and
Tegra186 (and later) memory controller drivers, unify the structures
that are used to represent them.
Note that this comes at a slight space penalty since some fields are
not used on all generations, but the benefits of unifying the driver
outweigh the downsides.

Subsequent patches will add more register fields to the tegra_mc_client

Arm Firmware Framework for ARMv8-A(FFA) interface driver
The Arm FFA specification describes a software architecture to
leverages the virtualization extension to isolate software images
provided by an ecosystem of vendors from each other and describes
interfaces that standardize communication between the various software
images including communication between images in the Secure world and
Normal world. Any Hypervisor could use the FFA interfaces to enable
communication between VMs it manages.
The Hypervisor a.k.a Partition managers in FFA terminology can assign
system resources(Memory regions, Devices, CPU cycles) to the partitions
and manage isolation amongst them.
This is the initial and minimal support for the FFA interface to enable
communication between secure partitions and the normal world OS.

Most of the MEM_* APIs share the same parameters, so they can be
generalised. Currently only MEM_SHARE is implemented and the user space
interface for that is not added yet.

Parse the FFA nodes from the device-tree and register all the partitions
whose services will be used in the kernel.
In order to also enable in-kernel users of FFA interface, let us add
simple set of operations for such devices.
The in-kernel users are registered without the character device interface.

The Arm FF for Armv8-A specification has concept of endpoints or
partitions. In the Normal world, a partition could be a VM when
the Virtualization extension is enabled or the kernel itself.
In order to handle multiple partitions, we can create a FFA device for
each such partition on a dedicated FFA bus. Similarly, different drivers
requiring FFA transport can be registered on the same bus. We can match
the device and drivers using UUID. This is mostly for the in-kernel
users with FFA drivers.

Pull ARM devicetree updates from Olof Johansson:
"Like always, the DT branch is sizable. There are numerous additions
and fixes to existing platforms, but also a handful of new ones
introduced. Less than some other releases, but there's been
significant work on cleanups, refactorings and device enabling on
existing platforms.
A non-exhaustive list of new material:
- Refactoring of BCM2711 dtsi structure to add support for the
Raspberry Pi 400
- Rockchip: RK3568 SoC and EVB, video codecs for
rk3036/3066/3188/322x
- Qualcomm: SA8155p Automotive platform (SM8150 derivative),
SM8150/8250 enhancements and support for Sony Xperia 1/1II and
5/5II
- TI K3: PCI/USB3 support on AM64-sk boards, R5 remoteproc
definitions
- TI OMAP: Various cleanups
- Tegra: Audio support for Jetson Xavier NX, SMMU support on Tegra194
- Qualcomm: lots of additions for peripherals across several SoCs,
and new support for Microsoft Surface Duo (SM8150-based), Huawei
Ascend G7.
- i.MX: Numerous additions of features across SoCs and boards.
- Allwinner: More device bindings for V3s, Forlinx OKA40i-C and
NanoPi R1S H5 boards
- MediaTek: More device bindings for mt8167, new Chromebook system
variants for mt8183
- Renesas: RZ/G2L SoC and EVK added
- Amlogic: BananaPi BPI-M5 board added"

Pull ARM SoC updates from Olof Johansson:
"A few SoC (code) changes have queued up this cycle, mostly for minor
changes and some refactoring and cleanup of legacy platforms. This
branch also contains a few of the fixes that weren't sent in by the
end of the release (all fairly minor).
- Adding an additional maintainer for the TEE subsystem (Sumit Garg)
- Quite a significant modernization of the IXP4xx platforms by Linus
Walleij, revisiting with a new PCI host driver/binding, removing
legacy mach/* include dependencies and moving platform
detection/config to drivers/soc. Also some updates/cleanup of
platform data.
- Core power domain support for Tegra platforms, and some
improvements in build test coverage by adding stubs for compile
test targets.
- A handful of updates to i.MX platforms, adding legacy (non-PSCI)
SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform
data and board fixups for iMX6/7.
... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
Rockchip"

This is a major chunk of IXP4xx modernization:
- Fist we move some registers around to make room for
the predetermined PCI I/O space.
- Then we add some Kconfig options to make it possible
to use the old PCI driver in parallell with the new
shiny one.
- Then we add the new PCI driver and some bindings for
it.
- On top of this we add an (ages old) patch from Arnd
that centralize the CPU/SoC detection in drivers/soc
and make the header a standard Linux header to avoid
the <mach/*> business in drivers.
- Then we split out and modernize some platform data
headers for pata, and hwrandom, and top it up with
DT bindings and support for hwrandom.

Generic drivers are unable to use the feature macros from mach/cpu.h
or the feature bits from mach/hardware.h, so move these into a global
header file along with some dummy helpers that list these features as
disabled elsewhere.

soc/tegra: Changes for v5.14-rc1
These changes implement the core power domain for the PMC, and fix a
couple of minor issues as well as add stubs to help some drivers be
compile tested more easily.

Add driver state syncing that is invoked once all PMC consumers are
attached and ready. The consumers are the power domain clients.
The synchronization callback is invoked once all client drivers are
probed, the driver core handles this for us. This callback informs
PMC driver that all voltage votes are initialized by each PD client
and it's safe to begin voltage scaling of the core power domain.

Problem:
On reconfigure of device, there is no way to defend if the backend
storage is matching with the initial backend storage.
Say, if an initial connect request for backend "pool1/image1" got
mapped to /dev/nbd0 and the userspace process is terminated. A next
reconfigure request within NBD_ATTR_DEAD_CONN_TIMEOUT is allowed to
use /dev/nbd0 for a different backend "pool1/image2"
For example, an operation like below could be dangerous:
$ sudo rbd-nbd map --try-netlink rbd-pool/ext4-image
/dev/nbd0
$ sudo blkid /dev/nbd0
/dev/nbd0: UUID="bfc444b4-64b1-418f-8b36-6e0d170cfc04" TYPE="ext4"
$ sudo pkill -9 rbd-nbd
$ sudo rbd-nbd attach --try-netlink --device /dev/nbd0 rbd-pool/xfs-image
/dev/nbd0
$ sudo blkid /dev/nbd0
/dev/nbd0: UUID="d29bf343-6570-4069-a9ea-2fa156ced908" TYPE="xfs"
Solution:
Provide a way for userspace processes to keep some metadata to identify
between the device and the backend, so that when a reconfigure request is
made, we can compare and avoid such dangerous operations.
With this solution, as part of the initial connect request, backend
path can be stored in the sysfs per device config, so that on a reconfigure
request it's easy to check if the backend path matches with the initial
connect backend path.
Please note, ioctl interface to nbd will not have these changes, as there
won't be any reconfigure.

This patch extends the vdpa_vq_state to support packed virtqueue
state which is basically the device/driver ring wrap counters and the
avail and used index. This will be used for the virito-vdpa support
for the packed virtqueue and the future vhost/vhost-vdpa support for
the packed virtqueue.

Currently all resources must be created with uid != 0 which is essential
when userspace processes are allocating virtquueue resources. Since this
is a kernel implementation, it is perfectly legal to open resources with
uid == 0.
In case firmware supports, avoid allocating user context.
