There are couple of places where INTA interrupt controller
lacks #interrupt-cells property. This leads to warnings of
the type:

Add the sub-mailbox nodes that are used to communicate between MPU and
various remote processors present in the J7200 SoCs to the J7200 common
processor board. These include the R5F remote processors in the dual-R5F
clusters in the MCU domain (MCU_R5FSS0) and the MAIN domain (MAIN_R5FSS0).
These sub-mailbox nodes utilize the System Mailbox clusters 0 and 1. All
the remaining mailbox clusters are currently not used on A72 core, and
so are disabled. The nodes are added in the k3-j7200-som-p0.dtsi file
to co-locate these alongside future reserved-memory nodes required for
remoteprocs.
The sub-mailbox nodes added match the hard-coded mailbox configuration
used within the TI RTOS IPC software packages. A sub-mailbox node is added
for each of the R5F cores to accommodate the R5F processor sub-systems
running in Split mode. Only the sub-mailbox node for the first R5F core in
each cluster is used in case of Lockstep mode for that R5F cluster.
NOTE:
The GIC_SPI interrupts to be used are dynamically allocated and managed
by the System Firmware through the ti-sci-intr irqchip driver. So, only
valid interrupts that are used by the sub-mailbox devices (each cluster's
User 0 IRQ output) are enabled. This is done to minimize the number of
NavSS Interrupt Router outputs utilized.

The J7200 Main NavSS block contains a Mailbox IP instance with
multiple clusters, and follows the same integration style as on
J721E SoCs.
Add all the Mailbox clusters as their own nodes under the MAIN
NavSS interconnect node instead of creating an almost empty parent
node for the new K3 mailbox IP and the clusters as its child nodes.
All these nodes are enabled by default in the base dtsi file, but
any cluster that does not define any child sub-mailbox nodes
should be disabled in the corresponding board dts files.
NOTE:
The NavSS only has a limited number of interrupts, so none of the
interrupts generated by a Mailbox IP are added by default. Only
the needed interrupts that are targeted towards the A72 GIC will
have to be added later on in the board dts files alongside the
corresponding sub-mailbox child nodes.

The device tree standard states that when the status property is
not present under a node, the okay value is assumed. There are many
reasons for doing the same, the number of strings in the device
tree, default power management functionality, etc. are a few of the
reasons.
In general, after a few rounds of discussions [1] there are few
options one could take when dealing with SoC dtsi and board dts
a. SoC dtsi provide nodes as a super-set default (aka enabled) state and
to prevent messy board files, when more boards are added per SoC, we
optimize and disable commonly un-used nodes in board-common.dtsi
b. SoC dtsi disables all hardware dependent nodes by default and board
dts files enable nodes based on a need basis.
c. Subjectively pick and choose which nodes we will disable by default
in SoC dtsi and over the years we can optimize things and change
default state depending on the need.
While there are pros and cons on each of these approaches, the right
thing to do will be to stick with device tree default standards and
work within those established rules. So, we choose to go with option
(a).
Lets cleanup defaults of j721e SoC dtsi before this gets more harder
to cleanup later on and new SoCs are added.
The only functional difference between the dtb generated is
status='okay' is no longer necessary for mcasp10 and depends on the
default state.
NOTE: There is a known risk of omission that new board dts developers
might miss reviewing both the board schematics in addition to all the
DT nodes of the SoC when setting appropriate nodes status to disable
or reserved in the board dts. This can expose issues in drivers that
may not anticipate an incomplete node (example: missing appropriate
board properties) being in an "okay" state. These cases are considered
bugs and need to be fixed in the drivers as and when identified.

Two carveout reserved memory nodes each have been added for each of the
R5F remote processor devices within both the MCU and MAIN domains for the
TI J721E EVM boards. These nodes are assigned to the respective rproc
device nodes as well. The first region will be used as the DMA pool for
the rproc device, and the second region will furnish the static carveout
regions for the firmware memory.
The current carveout addresses and sizes are defined statically for each
device. The R5F processors do not have an MMU, and as such require the
exact memory used by the firmwares to be set-aside. The firmware images
do not require any RSC_CARVEOUT entries in their resource tables either
to allocate the memory for firmware memory segments.
Note that the R5F1 carveouts are needed only if the R5F cluster is running
in Split (non-LockStep) mode. The reserved memory nodes can be disabled
later on if there is no use-case defined to use the corresponding
remote processor.

an Asymmetric Multi Processing (AMP) fashion in Split-mode. These
subsystems have 64 KB each Tightly-Coupled Memory (TCM) internal
memories for each core split between two banks - ATCM and BTCM
(further interleaved into two banks). There are some IP integration
differences from standard Arm R5 clusters such as the absence of
an ACP port, presence of an additional TI-specific Region Address
Translater (RAT) module for translating 32-bit CPU addresses into
larger system bus addresses etc.

the two R5F cores are each added as child nodes to the corresponding

location of the kernel git tree.
If GIT_DIR is unset, keep using the current ".git" default.

Pull more parisc updates from Helge Deller:
- During this merge window O_NONBLOCK was changed to become 000200000,
but we missed that the syscalls timerfd_create(), signalfd4(),
eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict
bit-wise check of the flags parameter.
To provide backward compatibility with existing userspace we
introduce parisc specific wrappers for those syscalls which filter
out the old O_NONBLOCK value and replaces it with the new one.
- Prevent HIL bus driver to get stuck when keyboard or mouse isn't
attached
- Improve error return codes when setting rtc time

Pull random32 updates from Willy Tarreau:
"Make prandom_u32() less predictable.
This is the cleanup of the latest series of prandom_u32
experimentations consisting in using SipHash instead of Tausworthe to
produce the randoms used by the network stack.
The changes to the files were kept minimal, and the controversial
commit that used to take noise from the fast_pool (f227e3ec3b5c) was
reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is
fed from various sources of activities (networking, scheduling) to
perturb the SipHash state using fast, non-trivially predictable data,
instead of keeping it fully deterministic. The goal is essentially to
make any occasional memory leakage or brute-force attempt useless.
The resulting code was verified to be very slightly faster on x86_64
than what is was with the controversial commit above, though this
remains barely above measurement noise. It was also tested on i386 and
arm, and build- tested only on arm64"

registering the ACPI i2c devs
Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().
But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().
Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.
This fixes the Microsoft Surface Go 2 hanging at boot.

Given that this code is new, let's add a selftest for it as well.
It doesn't rely on fixed sets, instead it picks 1024 numbers and
verifies that they're not more correlated than desired.
