dt-bindings: dp83867: add binding for io_impedance_ctrl nvmem cell
We have a board where measurements indicate that the current three
options - leaving IO_IMPEDANCE_CTRL at the reset value (which is
factory calibrated to a value corresponding to approximately 50 ohms)
or using one of the two boolean properties to set it to the min/max
value - are too coarse.
There is no fixed mapping from register values to values in the range
35-70 ohms; it varies from chip to chip, and even that target range is
approximate. So add a DT binding for an nvmem cell which can be
populated during production with a value suitable for each specific
board.

Problems observed:
======================================================================
1) Using ssh/sshfs. The remote sshd daemon can abort with the message:
"message authentication code incorrect"
This happens because the tcp message sent is corrupted during the
USB "Bulk out". The device calculate the tcp checksum and send a
valid tcp message to the remote sshd. Then the encryption detects
the error and aborts.
2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out
3) Stop normal work without any log message.
The "Bulk in" continue receiving packets normally.
The host sends "Bulk out" and the device responds with -ECONNRESET.
(The netusb.c code tx_complete ignore -ECONNRESET)
Under normal conditions these errors take days to happen and in
intense usage take hours.
A test with ping gives packet loss, showing that something is wrong:
ping -4 -s 462 {destination} # 462 = 512 - 42 - 8
Not all packets fail.
My guess is that the device tries to find another packet starting
at the extra byte and will fail or not depending on the next
bytes (old buffer content).

A board may have no independent reset-line, so reset cannot be used

E.g. on Bananapi-R2 Pro switch and gmac are connected to same reset-line.
Resets should be acquired only to 1 device/driver. This prevents reset to
be bound to switch-driver if reset is already used for gmac. If reset is
only used by switch driver it resets the switch *and* the gmac after the
mdio bus comes up resulting in mdio bus goes down. It takes some time
until all is up again, switch driver tries to read from mdio, will fail
and defer the probe. On next try the reset does the same again.

====================
mlxsw: Remove XM support
The XM was supposed to be an external device connected to the
Spectrum-{2,3} ASICs using dedicated Ethernet ports. Its purpose was to
increase the number of routes that can be offloaded to hardware. This was
achieved by having the ASIC act as a cache that refers cache misses to the
XM where the FIB is stored and LPM lookup is performed.
Testing was done over an emulator and dedicated setups in the lab, but
the product was discontinued before shipping to customers.
Therefore, in order to remove dead code and reduce complexity of the
code base, revert the three patchsets that added XM support.
====================
1) Updated HW bits and definitions for upcoming features
1.1) vport debug counters
1.2) flow meter
1.3) Execute ASO action for flow entry
1.4) enhanced CQE compression
2) Add ICM header-modify-pattern RDMA API
Leon Says
=========
SW steering manipulates packet's header using "modifying header" actions.
Many of these actions do the same operation, but use different data each time.
Currently we create and keep every one of these actions, which use expensive
and limited resources.
Now we introduce a new mechanism - pattern and argument, which splits
a modifying action into two parts:
1. action pattern: contains the operations to be applied on packet's header,
mainly set/add/copy of fields in the packet
2. action data/argument: contains the data to be used by each operation
in the pattern.
This way we reuse same patterns with different arguments to create new
modifying actions, and since many actions share the same operations, we end
up creating a small number of patterns that we keep in a dedicated cache.
These modify header patterns are implemented as new type of ICM memory,
so the following kernel patch series add the support for this new ICM type.

mlxsw: spectrum_cnt: Reorder counter pools
Both RIF and ACL flow counters use a 24-bit SW-managed counter address to
communicate which counter they want to bind.
In a number of Spectrum FW releases, binding a RIF counter is broken and
slices the counter index to 16 bits. As a result, on Spectrum-2 and above,
no more than about 410 RIF counters can be effectively used. This
translates to 205 netdevices for which L3 HW stats can be enabled. (This
does not happen on Spectrum-1, because there are fewer counters available
overall and the counter index never exceeds 16 bits.)
Binding counters to ACLs does not have this issue. Therefore reorder the
counter allocation scheme so that RIF counters come first and therefore get
lower indices that are below the 16-bit barrier.
When calling setattr_prepare() to determine the validity of the
attributes the ia_{g,u}id fields contain the value that will be written
to inode->i_{g,u}id. This is exactly the same for idmapped and
non-idmapped mounts and allows callers to pass in the values they want
to see written to inode->i_{g,u}id.
When group ownership is changed a caller whose fsuid owns the inode can
change the group of the inode to any group they are a member of. When
searching through the caller's groups we need to use the gid mapped
according to the idmapped mount otherwise we will fail to change
ownership for unprivileged users.
Consider a caller running with fsuid and fsgid 1000 using an idmapped
mount that maps id 65534 to 1000 and 65535 to 1001. Consequently, a file
owned by 65534:65535 in the filesystem will be owned by 1000:1001 in the
idmapped mount.
The caller now requests the gid of the file to be changed to 1000 going
through the idmapped mount. In the vfs we will immediately map the
requested gid to the value that will need to be written to inode->i_gid
and place it in attr->ia_gid. Since this idmapped mount maps 65534 to
1000 we place 65534 in attr->ia_gid.
When we check whether the caller is allowed to change group ownership we
first validate that their fsuid matches the inode's uid. The
inode->i_uid is 65534 which is mapped to uid 1000 in the idmapped mount.
Since the caller's fsuid is 1000 we pass the check.
We now check whether the caller is allowed to change inode->i_gid to the
requested gid by calling in_group_p(). This will compare the passed in
gid to the caller's fsgid and search the caller's additional groups.
Since we're dealing with an idmapped mount we need to pass in the gid
mapped according to the idmapped mount. This is akin to checking whether
a caller is privileged over the future group the inode is owned by. And
that needs to take the idmapped mount into account. Note, all helpers
are nops without idmapped mounts.
The AMD XGbE driver currently counts the number of interrupts assigned
to the device by inspecting the pdev->resource array. Since commit 55098b87fc23 ("of/platform: Drop static setup of IRQ resource from DT

interrupts from 1 to -1U and gives up probing once it reaches an invalid
interrupt index.

64-bit RISC-V machines. The errors indicated that the DMA had fetched a
null descriptor and we found that the reason for this is that AXI DMA had
unexpectedly processed a partially updated tail descriptor pointer. To
fix it, we suggest that the driver should use one 64-bit write instead
of two 32-bit writes to perform such update if possible. For those
archectures where double-word load/stores are unavailable, e.g. 32-bit

net: axienet: Use iowrite64 to write all 64b descriptor pointers
According to commit d75c3557c289 ("net: axienet: Autodetect 64-bit DMA
capability") and AXI-DMA spec (pg021), on 64-bit capable dma, only
writing MSB part of tail descriptor pointer causes DMA engine to start
fetching descriptors. However, we found that it is true only if dma is in
idle state. In other words, dma would use a tailp even if it only has LSB
updated, when the dma is running.
The non-atomicity of this behavior could be problematic if enough
delay were introduced in between the 2 writes. For example, if an
interrupt comes right after the LSB write and the cpu spends long
enough time in the handler for the dma to get back into idle state by
completing descriptors, then the seconcd write to MSB would treat dma
to start fetching descriptors again. Since the descriptor next to the
one pointed by current tail pointer is not filled by the kernel yet,
fetching a null descriptor here causes a dma internal error and halt
the dma engine down.
We suggest that the dma engine should start process a 64-bit MMIO write
to the descriptor pointer only if ONE 32-bit part of it is written on all
states. Or we should restrict the use of 64-bit addressable dma on 32-bit
platforms, since those devices have no instruction to guarantee the write
to LSB and MSB part of tail pointer occurs atomically to the dma.
