In zynqmp platforms where firmware supports dynamic SGMII configuration
but has other non-SGMII ethernet devices, it fails them with no packets
received at the RX interface.
To fix this behaviour perform SGMII dynamic configuration only
for the SGMII phy interface.

When vdosys1 was initially added, it was incorrectly assumed to be
compatible with vdosys0, and thus both had the same mt8195-mmsys
compatible attached.
This has since been corrected in commit b237efd47d ("dt-bindings:
arm: mediatek: mmsys: change compatible for MT8195") and commit
82219cfbef ("dt-bindings: arm: mediatek: mmsys: add vdosys1 compatible
for MT8195"). The device tree needs to be fixed as well, otherwise
the vdosys1 block fails to work, and causes its dependent power domain
controller to not work either.
Change the compatible string of vdosys1 to "mediatek,mt8195-vdosys1".
While at it, also add the new "mediatek,mt8195-vdosys0" compatible to
vdosys0.

After calling fwnode_phy_find_device(), the phy device refcount is
incremented. Then, when the phy device is attached to a netdev with
phy_attach_direct(), the refcount is also incremented but only
decremented in the caller if phy_attach_direct() fails. Move
phy_device_free() before the "if" to always release it correctly.
Indeed, either phy_attach_direct() failed and we don't want to keep a
reference to the phydev or it succeeded and a reference has been taken
internally.

Commit 7a8b64d17e ("of/address: use range parser for of_dma_get_range")
converted the parsing of dma-range properties to use code shared with the
PCI range parser. The intent was to introduce no functional changes however
in the case where we fail to translate the first resource instead of
returning -EINVAL the new code we return 0. Restore the previous behaviour
by returning an error if we find no valid ranges, the original code only
handled the first range but subsequently support for parsing all supplied
ranges was added.
This avoids confusing code using the parsed ranges which doesn't expect to
successfully parse ranges but have only a list terminator returned, this
fixes breakage with so far as I can tell all DMA for on SoC devices on the
Socionext Synquacer platform which has a firmware supplied DT. A bisect
identified the original conversion as triggering the issues there.

This is because multiple devices with the same name 'of-display' are

for the displays.
Also, fix a node refcounting issue when exiting the boot display loop.

poll() and select() on per_cpu trace_pipe and trace_pipe_raw do not work
since kernel 6.1-rc6. This issue is seen after the commit
42fb0a1e84 ("tracing/ring-buffer: Have
polling block on watermark").
This issue is firstly detected and reported, when testing the CXL error
events in the rasdaemon and also erified using the test application for poll()
and select().
This issue occurs for the per_cpu case, when calling the ring_buffer_poll_wait(),
in kernel/trace/ring_buffer.c, with the buffer_percent > 0 and then wait until the
percentage of pages are available. The default value set for the buffer_percent is 50
in the kernel/trace/trace.c.
As a fix, allow userspace application could set buffer_percent as 0 through
the buffer_percent_fops, so that the task will wake up as soon as data is added
to any of the specific cpu buffer.

The majority of bugfixes is once more for the NXP i.MX platform,
addressing issue with i.MX8M (UART, watchdog and ethernet) as well as
imx8dxl power button and the USB modem on an imx7 board. The reason that
i.MX always shows up here is obviously not that they are more buggy than
the others, but they have the most boards and are good about getting
fixes in quickly.
The other DT fixes are for the Nuvoton wpcm450 flash controller and
the i2c mux on an ASpeed board.
Lastly, there are updates to the MAINTAINERS entries for Mediatek,
AMD/Seattle and NXP SoCs, as well as a lone code fix for error
handling in the allwinner "rsb" bus driver.

- With CONFIG_VMAP_STACK enabled it is not possible to load the s390
specific diag288_wdt watchdog module. Reason is that a pointer to a
string is passed to an inline assembly; this string however is located on
the stack, while the instruction within the inline assembly expects a
physicial address. Fix this by copying the string to a kmalloc'ed buffer.
- The diag288_wdt watchdog module does not indicate that it accesses memory
from an inline assembly, which it does. Add "memory" to the clobber list
to prevent the compiler from optimizing code incorrectly away.
- Pass size of the uncompressed kernel image to __decompress() call.

Currently there is no IRQ handling (even the SGMII supports it).
Enable polling to support SFP ports.

The code expect the PHY to be in power down which is only true after reset.
Allow changes of the SGMII parameters more than once.
Only power down when reconfiguring to avoid bouncing the link when there's
no reason to - based on code from Russell King.
There are cases when the SGMII_PHYA_PWD register contains 0x9 which
prevents SGMII from working. The SGMII still shows link but no traffic
can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was
taken from a good working state of the SGMII interface.

The first patch is by Ziyang Xuan and removes a errant WARN_ON_ONCE()
in the CAN J1939 protocol.
The next 3 patches are by Oliver Hartkopp. The first 2 target the CAN
ISO-TP protocol and fix the state machine with respect to signals and
a regression found by the syzbot.
The last patch is by me an missing assignment during the ethtool ring
configuration callback.

the interrupts are generated which causes spurious interrupts unhandled.

When received corrupted snap trace we don't know what exactly has
happened in MDS side. And we shouldn't continue IOs and metadatas
access to MDS, which may corrupt or get incorrect contents.
This patch will just block all the further IO/MDS requests
immediately and then evict the kclient itself.
The reason why we still need to evict the kclient just after
blocking all the further IOs is that the MDS could revoke the caps
faster.

The test tool can check that the zerocopy number of completions value is
valid taking into consideration the number of datagram send calls. This can
catch the system into a state where the datagrams are still in the system
(for example in a qdisk, waiting for the network interface to return a
completion notification, etc).
This change adds a retry logic of computing the number of completions up to
a configurable (via CLI) timeout (default: 2 seconds).
