If the device is running older pcode firmware, it is possible that newer
mailbox commands are not supported by it. The sysfs attributes aren't
useful in that case, but we shouldn't fail driver probe because of it.
As of now, it is unknown if we can distinguish unsupported commands before
attempting them. But until we figure out a way to do that, fix the
regressions.

Before commit df6d7277e552 ("i2c: core: Do not dereference fwnode in struct
device"), i2c_unregister_device() only called fwnode_handle_put() on
of_node-s in the form of calling of_node_put(client->dev.of_node).
But after this commit the i2c_client's fwnode now unconditionally gets
fwnode_handle_put() on it.
When the i2c_client has no primary (ACPI / OF) fwnode but it does have
a software fwnode, the software-node will be the primary node and
fwnode_handle_put() will put() it.
But for the software fwnode device_remove_software_node() will also put()
it leading to a double free:

Add support for the Texas Instruments INA228 Ultra-Precise
Power/Energy/Charge Monitor.
The INA228 is very similar to the INA238 but offers four bits of extra
precision in the temperature, voltage and current measurement fields.
It also supports energy and charge monitoring, the latter of which is
not supported through this patch.
While it seems in the datasheet that some constants such as LSB values
differ between the 228 and the 238, they differ only for those registers
where four bits of precision have been added and they differ by a factor
of 16 (VBUS, VSHUNT, DIETEMP, CURRENT).
Therefore, the INA238 constants are still applicable with regard
to the bit of the same significance.

QAT devices perform an additional integrity check during compression by
decompressing the output. Starting from QAT GEN4, this verification is
done in-line by the hardware. However, on GEN2 devices, the hardware
reads back the compressed output from the destination buffer and performs
a decompression operation using it as the source.
In the current QAT driver, destination buffers are always marked as
write-only. This is incorrect for QAT GEN2 compression, where the buffer
is also read during verification. Since commit 6f5dc7658094
("iommu/vt-d: Restore WO permissions on second-level paging entries"),
merged in v6.16-rc1, write-only permissions are strictly enforced, leading
to DMAR errors when using QAT GEN2 devices for compression, if VT-d is
enabled.
Mark the destination buffers as DMA_BIDIRECTIONAL. This ensures
compatibility with GEN2 devices, even though it is not required for
QAT GEN4 and later.

A few drivers that use the legacy GPIOLIB interfaces can be enabled
even when GPIOLIB is disabled entirely. With my previous patch this
now causes build failures like:
drivers/nfc/s3fwrn5/uart.c: In function 's3fwrn82_uart_parse_dt':
drivers/nfc/s3fwrn5/uart.c:100:14: error: implicit declaration of function 'gpio_is_valid'; did you mean 'uuid_is_valid'? [-Werror=implicit-function-declaration]
These did not show up in my randconfig tests because randconfig almost
always has GPIOLIB selected by some other driver, and I did most
of the testing with follow-up patches that address the failures
properly.
Move the symbol outside of the 'if CONFIG_GPIOLIB' block for the moment
to avoid the build failures. It can be moved back and turned off by
default once all the driver specific changes are merged.

There is no break time in the while() loop, so every time at the end of
igb_xmit_zc(), negative overflow of nb_pkts will occur, which renders
the return value always false. But theoretically, the result should be
set after calling xsk_tx_peek_release_desc_batch(). We can take
i40e_xmit_zc() as a good example.
Returning false means we're not done with transmission and we need one
more poll, which is exactly what igb_xmit_zc() always did before this
patch. After this patch, the return value depends on the nb_pkts value.
Two cases might happen then:
1. if (nb_pkts < budget), it means we process all the possible data, so
return true and no more necessary poll will be triggered because of
this.
2. if (nb_pkts == budget), it means we might have more data, so return
false to let another poll run again.

A negative overflow can happen when the budget number of descs are
consumed. as long as the budget is decreased to zero, it will again go
into while (budget-- > 0) statement and get decreased by one, so the
overflow issue can happen. It will lead to returning true whereas the
expected value should be false.
In this case where all the budget is used up, it means zc function
should return false to let the poll run again because normally we
might have more data to process. Without this patch, zc function would
return true instead.

way of storing timestamp directly in a reserved field inside the PTP
message header is not suitable for use with the current Linux PTP stack
implementation. It is necessary to disable the PTP function to not
interfere the normal operation of the MAC.
Note the PTP driver for KSZ switches does not work for KSZ8463 and is not

KSZ8463 switch is a 3-port switch based from KSZ8863. Its major
difference from other KSZ SPI switches is its register access is not a
simple continual 8-bit transfer with automatic address increase but uses
a byte-enable mechanism specifying 8-bit, 16-bit, or 32-bit access. Its
registers are also defined in 16-bit format because it shares a design
with a MAC controller using 16-bit access. As a result some common
register accesses need to be re-arranged.
This patch adds the basic structure for using KSZ8463. It cannot use the
same regmap table for other KSZ switches as it interprets the 16-bit
value as little-endian and its SPI commands are different.
KSZ8463 uses a byte-enable mechanism to specify 8-bit, 16-bit, and 32-bit
access. The register is first shifted right by 2 then left by 4. Extra
4 bits are added. If the access is 8-bit one of the 4 bits is set. If
the access is 16-bit two of the 4 bits are set. If the access is 32-bit
all 4 bits are set. The SPI command for read or write is then added.
Because of this register transformation separate SPI read and write
functions are provided for KSZ8463.
KSZ8463's internal PHYs use standard PHY register definitions so there is
no need to remap things. However, the hardware has a bug that the high
word and low word of the PHY id are swapped. In addition the port
registers are arranged differently so KSZ8463 has its own mapping for
port registers and PHY registers. Therefore the PORT_CTRL_ADDR macro is
replaced with the get_port_addr helper function.

libie: commonize adminq structure
Michal Swiatkowski says:
It is a prework to allow reusing some specific Intel code (eq. fwlog).
Move common *_aq_desc structure to libie header and changing
it in ice, ixgbe, i40e and iavf.
Only generic adminq commands can be easily moved to common header, as
rest is slightly different. Format remains the same. It will be better
to correctly move it when it will be needed to commonize other part of
the code.
Move *_aq_str() to new libie module (libie_adminq) and use it across
drivers. The functions are exactly the same in each driver. Some more
adminq helpers/functions can be moved to libie_adminq when needed.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
i40e: use libie_aq_str
iavf: use libie_aq_str
ice: use libie_aq_str
libie: add adminq helper for converting err to str
iavf: use libie adminq descriptors
i40e: use libie adminq descriptors
ixgbe: use libie adminq descriptors
ice, libie: move generic adminq descriptors to lib

As part of the removal of the variably-sized sockaddr for kernel
internals, replace struct sockaddr with sockaddr_inet in the endpoint
union.
No binary changes; the union size remains unchanged due to sockaddr_inet
matching the size of sockaddr_in6.

Remote IPsec tunnel endpoint may refer to a network segment that is
not directly connected to the host. In such a case, IPsec tunnel
endpoints are connected to a router and reachable via a routing path.
In IPsec packet offload mode, HW is initialized with the MAC address
of both IPsec tunnel endpoints.
Extend the current IPsec init MACs procedure to resolve nexthop for
routed networks. Direct neighbour lookup and probe is still used
for directly connected networks and as a fallback mechanism if fib
lookup fails.

Rework the read and write code paths in the driver to support operation
in atomic contexts. To achieve this, the driver must not rely on IRQs
or perform any scheduling, e.g., via a sleep or schedule routine.
Implement atomic, sleep-free, and IRQ-less operation. This increases
complexity but is necessary for atomic I2C transfers required by some
hardware configurations, e.g., to trigger reboots on an external PMIC chip.

Commit 21b688dabecb ("net: phy: micrel: Cable Diag feature for lan8814
phy") introduced cable_test support for the LAN8814 that reuses parts of
the KSZ886x logic and introduced the cable_diag_reg and pair_mask
parameters to account for differences between those chips.
However, it did not update the ksz8081_type struct, so those members are
now 0, causing no pairs to be tested in ksz886x_cable_test_get_status
and ksz886x_cable_test_wait_for_completion to poll the wrong register
for the affected PHYs (Basic Control/Reset, which is 0 in normal
operation) and exit immediately.
Fix this by setting both struct members accordingly.
