The first reg region in this binding is not exclusively for clocks, as
evidenced by the dual role of this device as a reset controller at
present. The first region is however better described by a simple-mfd
syscon, but this would have require a significant re-write of the
devicetree for the platform, so the easy way out was chosen when reset
support was first introduced. The region doesn't just contain clock and
reset registers, it also contains pinctrl and interrupt controller
functionality, so drop the region from the clock binding so that it can
be described instead by a simple-mfd syscon rather than propagate this
incorrect description of the hardware to the new pic64gx SoC.

Phase-adjust values are currently limited by a min-max range. Some
hardware requires, for certain pin types, that values be multiples of
a specific granularity, as in the zl3073x driver.
Add a `phase-adjust-gran` pin attribute and an appropriate field in
dpll_pin_properties. If set by the driver, use its value to validate
user-provided phase-adjust values.

Add the TPS23881B I2C power sourcing equipment controller to the list of
supported devices.
Falling back to the TPS23881 predecessor device is not suitable as firmware
loading needs to handled differently by the driver. The TPS23881 and
TPS23881B devices require different firmware. Trying to load the TPS23881
firmware on a TPS23881B device fails and must therefore be omitted.

Add 'reg' and 'clocks' properties to enable QoS configuration. These
properties enable access to QoS registers and necessary clocks for
configuration.
QoS configuration is essential for ensuring that latency sensitive
components such as CPUs and multimedia engines receive prioritized
access to memory and interconnect resources. This helps to manage
bandwidth and latency across subsystems, improving system responsiveness
and performance in concurrent workloads.
Both 'reg' and 'clocks' properties are optional. If either is missing,
QoS configuration will be skipped. This behavior is controlled by the
'qos_requires_clocks' flag in the driver, which ensures that QoS
configuration is bypassed when required clocks are not defined.

Add a sysfs attribute `/sys/power/hibernate_compression_threads` to
allow runtime configuration of the number of threads used for
compressing and decompressing hibernation images.
The new sysfs interface enables dynamic adjustment at runtime:
# cat /sys/power/hibernate_compression_threads
3
# echo 4 > /sys/power/hibernate_compression_threads
This change provides greater flexibility for debugging and performance
tuning of hibernation without requiring a reboot.

The number of compression/decompression threads has a direct impact on
hibernate image generation and resume latency. Using more threads can
reduce overall resume time, but on systems with fewer CPU cores it may
also introduce contention and reduce efficiency.
Performance was evaluated on an 8-core ARM system, averaged over 10 runs:
Threads Hibernate(s) Resume(s)
--------------------------------
3 12.14 18.86
4 12.28 17.48
5 11.09 16.77
6 11.08 16.44
With 5–6 threads, resume latency improves by approximately 12% compared
to the default 3-thread configuration, with negligible impact on
hibernate time.
Introduce a new kernel parameter `hibernate_compression_threads=` that
allows users and integrators to tune the number of
compression/decompression threads at boot. This provides a way to
balance performance and CPU utilization across a wide range of hardware
without recompiling the kernel.

Currently if a -ENOMEM from smc_wr_alloc_link_mem() is handled by
giving up and going the way of a TCP fallback. This was reasonable
before the sizes of the allocations there were compile time constants
and reasonably small. But now those are actually configurable.
So instead of giving up, keep retrying with half of the requested size
unless we dip below the old static sizes -- then give up! In terms of
numbers that means we give up when it is certain that we at best would
end up allocating less than 16 send WR buffers or less than 48 recv WR
buffers. This is to avoid regressions due to having fewer buffers
compared the static values of the past.
Please note that SMC-R is supposed to be an optimisation over TCP, and
falling back to TCP is superior to establishing an SMC connection that
is going to perform worse. If the memory allocation fails (and we
propagate -ENOMEM), we fall back to TCP.
Preserve (modulo truncation) the ratio of send/recv WR buffer counts.

Think SMC_WR_BUF_CNT_SEND := SMC_WR_BUF_CNT used in send context and
SMC_WR_BUF_CNT_RECV := 3 * SMC_WR_BUF_CNT used in recv context. Those
get replaced with lgr->max_send_wr and lgr->max_recv_wr respective.
Please note that although with the default sysctl values
qp_attr.cap.max_send_wr == qp_attr.cap.max_recv_wr is maintained but
can not be assumed to be generally true any more. I see no downside to
that, but my confidence level is rather modest.

The ENETC with pseudo MAC is used to connect to the CPU port of the NETC
switch. This ENETC has a different PCI device ID, so add a standard PCI
device compatible string to it.

Add the ability to append the incoming IP interface information to
ICMPv6 error messages in accordance with RFC 5837 and RFC 4884. This is
required for more meaningful traceroute results in unnumbered networks.
The feature is disabled by default and controlled via a new sysctl
("net.ipv6.icmp.errors_extension_mask") which accepts a bitmask of ICMP
extensions to append to ICMP error messages. Currently, only a single
value is supported, but the interface and the implementation should be
able to support more extensions, if needed.
Clone the skb and copy the relevant data portions before modifying the
skb as the caller of icmp6_send() still owns the skb after the function
returns. This should be fine since by default ICMP error messages are
rate limited to 1000 per second and no more than 1 per second per
specific host.
Trim or pad the packet to 128 bytes before appending the ICMP extension
structure in order to be compatible with legacy applications that assume
that the ICMP extension structure always starts at this offset (the
minimum length specified by RFC 4884).
Since commit 20e1954fe238 ("ipv6: RFC 4884 partial support for SIT/GRE
tunnels") it is possible for icmp6_send() to be called with an skb that
already contains ICMP extensions. This can happen when we receive an
ICMPv4 message with extensions from a tunnel and translate it to an
ICMPv6 message towards an IPv6 host in the overlay network. I could not
find an RFC that supports this behavior, but it makes sense to not
overwrite the original extensions that were appended to the packet.
Therefore, avoid appending extensions if the length field in the
provided ICMPv6 header is already filled.
Export netdev_copy_name() using EXPORT_IPV6_MOD_GPL() to make it
available to IPv6 when it is built as a module.

http://www.uwsg.iu.edu/ doesn't seem to exist anymore.
I managed to find backups on archive.org, which helped me find
the right links on https://lore.kernel.org/.
http://freecode.com/projects/afio was also down, so I figured
it could be replaced with https://linux.die.net/man/1/afio.
Replace broken links to mailing list and aifo tool.

Document the Synaptics TDDI (Touch/Display Integration) panel hardware.
Along with the MIPI-DSI panel, these devices also have an in-built LED
backlight device and a touchscreen, all packed together in a single chip.
Also, add compatibles for supported panels - TD4101 and TD4300. Both
have the '-panel' suffix so as to remove any ambiguity between the panel
and touchscreen chips.
