The CANFD block on the RZ/Five SoC is identical to one found on the
RZ/G2UL SoC. "renesas,r9a07g043-canfd" compatible string will be used
on the RZ/Five SoC so to make this clear, update the comment to include
RZ/Five SoC.
No driver changes are required as generic compatible string
"renesas,rzg2l-canfd" will be used as a fallback on RZ/Five SoC.

Add an option to initialize SOF_TIMESTAMPING_OPT_ID for TCP from
write_seq sockets instead of snd_una.
This should have been the behavior from the start. Because processes
may now exist that rely on the established behavior, do not change
behavior of the existing option, but add the right behavior with a new
flag. It is encouraged to always set SOF_TIMESTAMPING_OPT_ID_TCP on
stream sockets along with the existing SOF_TIMESTAMPING_OPT_ID.
Intuitively the contract is that the counter is zero after the
setsockopt, so that the next write N results in a notification for
the last byte N - 1.
On idle sockets snd_una == write_seq and this holds for both. But on
sockets with data in transmission, snd_una records the unacked offset
in the stream. This depends on the ACK response from the peer. A
process cannot learn this in a race free manner (ioctl SIOCOUTQ is one
racy approach).
write_seq records the offset at the last byte written by the process.
This is a better starting point. It matches the intuitive contract in
all circumstances, unaffected by external behavior.
The new timestamp flag necessitates increasing sk_tsflags to 32 bits.
Move the field in struct sock to avoid growing the socket (for some
common CONFIG variants). The UAPI interface so_timestamping.flags is
already int, so 32 bits wide.

Expose port function commands to enable / disable migratable
capability, this is used to set the port function as migratable.
Live migration is the process of transferring a live virtual machine
from one physical host to another without disrupting its normal
operation.
In order for a VM to be able to perform LM, all the VM components must
be able to perform migration. e.g.: to be migratable.
In order for VF to be migratable, VF must be bound to VFIO driver with
migration support.
When migratable capability is enabled for a function of the port, the
device is making the necessary preparations for the function to be
migratable, which might include disabling features which cannot be
migrated.
Example of LM with migratable function configuration:
Set migratable of the VF's port function.
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0
vfnum 1
function:
hw_addr 00:00:00:00:00:00 migratable disable
$ devlink port function set pci/0000:06:00.0/2 migratable enable
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0
vfnum 1
function:
hw_addr 00:00:00:00:00:00 migratable enable
Bind VF to VFIO driver with migration support:
$ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/unbind
$ echo mlx5_vfio_pci > /sys/bus/pci/devices/0000:08:00.0/driver_override
$ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/bind
Attach VF to the VM.
Start the VM.

Expose port function commands to enable / disable RoCE, this is used to

dpaa2_mac_is_type_fixed() is a header with no implementation and no

On the other hand, it would be useful to reuse the code between
dpaa2_eth_is_type_phy() and dpaa2_switch_port_is_type_phy(). That common
code should be called dpaa2_mac_is_type_phy(), so let's create that.
The removal and the addition are merged into the same patch because,
in fact, is_type_phy() is the logical opposite of is_type_fixed().

To read from a region, user space must currently request a new snapshot of
the region and then read from that snapshot. This can sometimes be overkill
if user space only reads a tiny portion. They first create the snapshot,
then request a read, then destroy the snapshot.
For regions which have a single underlying "contents", it makes sense to
allow supporting direct reading of the region data.
Extend the DEVLINK_CMD_REGION_READ to allow direct reading from a region if
requested via the new DEVLINK_ATTR_REGION_DIRECT. If this attribute is set,
then perform a direct read instead of using a snapshot. Direct read is
mutually exclusive with DEVLINK_ATTR_REGION_SNAPSHOT_ID, and care is taken
to ensure that we reject commands which provide incorrect attributes.
Regions must enable support for direct read by implementing the .read()
callback function. If a region does not support such direct reads, a
suitable extended error message is reported.

This reverts commit 40acc05271abc2852c32622edbebd75698736b9b.
marvell,prestera.txt is an old file describing the old Alleycat3
standalone switches. The commit mentioned above actually hacked these
bindings to add support for a device tree property for a more modern
version of the IP connected over PCI, using only the generic compatible
in order to retrieve the device node from the prestera driver to read
one static property.
The problematic property discussed here is "base-mac-provider". The
original intent was to point to a nvmem device which could produce the
relevant nvmem-cell. This property has never been acked by DT
maintainers and fails all the layering that has been brought with the nvmem
bindings by pointing at a nvmem producer, bypassing the existing nvmem
bindings, rather than a nvmem cell directly. Furthermore, the property
cannot even be used upstream because it expected the ONIE tlv driver to
produce a specific cell, driver which used nacked bindings and thus was
never merged, replaced by a more integrated concept: the nvmem-layout.
So let's forget about this temporary addition, safely avoiding the need
for any backward compatibility handling. A new (yaml) binding file will
be brought with the prestera bindings, and there we will actually
include a description of the modern IP over PCI, including the right way
to point to a nvmem cell.

Pull power management fixes from Rafael Wysocki:
"These revert a recent change in the schedutil cpufreq governor that
had not been expected to make any functional difference, but turned
out to introduce a performance regression, fix an initialization issue
in the amd-pstate driver and make it actually replace the venerable
ACPI cpufreq driver on the supported systems by default.
Specifics:
- Revert a recent schedutil cpufreq governor change that introduced a
performace regression on Pixel 6 (Sam Wu)
- Fix amd-pstate driver initialization after running the kernel via
kexec (Wyes Karny)
- Turn amd-pstate into a built-in driver which allows it to take
precedence over acpi-cpufreq by default on supported systems and
amend it with a mechanism to disable this behavior (Perry Yuan)
- Update amd-pstate documentation in accordance with the other
changes made to it (Perry Yuan)"

Pull ARM SoC fixes from Arnd Bergmann:
"There are a bunch of late fixes that just came in, in particular a
longer series for Rockchips devicetree files, but most of those just
address cosmetic errors that were found during the binding validation.
There are a couple of code changes:
- A regression fix to the IXP42x PCI bus
- A fix for a memory leak on optee, and another one for mach-mxs
- Two fixes for the sunxi rsb bus driver, to address problems with
the shutdown logic
The rest are small but important devicetree fixes for a number of
individual boards, addressing issues across all platforms:
- arm global timer on older rockchip SoCs is unstable and needs to be
disabled in favor of a more reliable clocksource
- Corrections to fix bluetooth, mmc, and networking on a few Rockchip
boards
- at91/sam9g20ek UDC needs a pin controller config change
- an omap board runs into mmc probe errors because of regulator nodes
in the wrong place
- imx8mp-evk has a minor inaccuracy with its pin config, but without
user visible impact
- The Allwinner H6 Hantro G2 video decoder needs an IOMMU reference
to prevent the driver from crashing"

Sphinx version >=3.1 warns about duplicate function declarations in the
DEVMAP documentation. This is because the function name is the same for
kernel and user space BPF progs but the parameters and return types
they take is what differs. This patch moves from using the ``c:function::``
directive to using the ``code-block:: c`` directive. The patches also fix
the indentation for the text associated with the "new" code block delcarations.
The missing support of c:namespace-push:: and c:namespace-pop:: directives by
helper scripts for kernel documentation prevents using the ``c:function::``
directive with proper namespacing.

Port documentation
kernel test robot reported indentation warnings:
Documentation/networking/devlink/devlink-port.rst:220: WARNING: Unexpected indentation.
Documentation/networking/devlink/devlink-port.rst:222: WARNING: Block quote ends without a blank line; unexpected unindent.
These warnings cause lists (arbitration flow for which the warnings blame to
and 3-step subfunction setup) to be rendered inline instead. Also, for the
former list, automatic list numbering is messed up.
Fix these warnings by adding missing blank line padding.

Add a new amd pstate driver command line option to enable driver passive
working mode via MSR and shared memory interface to request desired
performance within abstract scale and the power management firmware
(SMU) convert the perf requests into actual hardware pstates.
Also the `disable` parameter can disable the pstate driver loading by
adding `amd_pstate=disable` to kernel command line.
