In preparation for MT7988 and RSS/LRO allow the interrupt-names
property.
In this way driver can request the interrupts by name which is much
more readable in the driver code and SoC's dtsi than relying on a
specific order.
Frame-engine-IRQs (fe0..3):
MT7621, MT7628: 1 FE-IRQ
MT7622, MT7623: 3 FE-IRQs (only two used by the driver for now)
MT7981, MT7986: 4 FE-IRQs (only two used by the driver for now)
RSS/LRO IRQs (pdma0..3) additional only on Filogic (MT798x) with
count of 4. So all IRQ-names (8) for Filogic.
Set boundaries for all compatibles same as irq count.

Increase the maximum IRQ count to 8 (4 FE + 4 RSS/LRO).
Frame-engine-IRQs (max 4):
MT7621, MT7628: 1 FE-IRQ
MT7622, MT7623: 3 FE-IRQs (only two used by the driver for now)
MT7981, MT7986, MT7988: 4 FE-IRQs (only two used by the driver for now)
Mediatek Filogic SoCs (mt798x) have 4 additional IRQs for RSS and/or
LRO. So MT798x have 8 IRQs in total.
MT7981 does not have a ethernet-node yet.
MT7986 Ethernet node is updated with RSS/LRO IRQs in this series.
MT7988 Ethernet node is added in this series.

This patch provides a setsockopt method to let applications leverage to
adjust how many descs to be handled at most in one send syscall. It
mitigates the situation where the default value (32) that is too small
leads to higher frequency of triggering send syscall.
Considering the prosperity/complexity the applications have, there is no
absolutely ideal suggestion fitting all cases. So keep 32 as its default
value like before.
The patch does the following things:
- Add XDP_MAX_TX_SKB_BUDGET socket option.
- Set max_tx_budget to 32 by default in the initialization phase as a
per-socket granular control.
- Set the range of max_tx_budget as [32, xs->tx->nentries].
The idea behind this comes out of real workloads in production. We use a
user-level stack with xsk support to accelerate sending packets and
minimize triggering syscalls. When the packets are aggregated, it's not
hard to hit the upper bound (namely, 32). The moment user-space stack
fetches the -EAGAIN error number passed from sendto(), it will loop to try
again until all the expected descs from tx ring are sent out to the driver.
Enlarging the XDP_MAX_TX_SKB_BUDGET value contributes to less frequency of
sendto() and higher throughput/PPS.
Here is what I did in production, along with some numbers as follows:
For one application I saw lately, I suggested using 128 as max_tx_budget
because I saw two limitations without changing any default configuration:
1) XDP_MAX_TX_SKB_BUDGET, 2) socket sndbuf which is 212992 decided by
net.core.wmem_default. As to XDP_MAX_TX_SKB_BUDGET, the scenario behind
this was I counted how many descs are transmitted to the driver at one
time of sendto() based on [1] patch and then I calculated the
possibility of hitting the upper bound. Finally I chose 128 as a
suitable value because 1) it covers most of the cases, 2) a higher
number would not bring evident results. After twisting the parameters,
a stable improvement of around 4% for both PPS and throughput and less
resources consumption were found to be observed by strace -c -p xxx:
1) %time was decreased by 7.8%
2) error counter was decreased from 18367 to 572

On some platforms, device dependencies are not properly represented by
device links, which can cause issues when asynchronous power management
is enabled. While it is possible to disable this via sysfs, doing so
at runtime can race with the first system suspend event.
This patch introduces a kernel command-line parameter, "pm_async", which
can be set to "off" to globally disable asynchronous suspend and resume
operations from early boot. It effectively provides a way to set the
initial value of the existing pm_async sysfs knob at boot time. This
offers a robust method to fall back to synchronous (sequential)
operation, which can stabilize platforms with problematic dependencies
and also serve as a useful debugging tool.
The default behavior remains unchanged (asynchronous enabled). To
disable it, boot the kernel with the "pm_async=off" parameter.

The AM62D2 SoC, part of the K3 architecture, is built for high-performance
DSP tasks in automotive audio, pro audio, radar, sonar, and medical
imaging. It features up to four Cortex-A53 cores (1.4GHz), two Cortex-R5F
cores, and a C7x DSP with 2 TOPS MMA. Key interfaces include multi-channel
McASP audio, TSN-capable Gigabit Ethernet, and a range of peripherals
(UART, SPI, I2C, CAN, USB, eMMC/SD, OSPI, CSI). It supports LPDDR4/DDR4,
secure boot with hardware security, and low-power modes with
CAN/GPIO/UART wakeup.
This SoC is of part K3 AM62x family, which includes the AM62A and AM62P
variants. A key distinction is that the AM62D does not include multimedia
components such as the video encoder/decoder, MJPEG encoder, Vision
Processing Accelerator (VPAC) for image signal processing, or the display
subsystem. Additionally, the AM62D has a different pin configuration
compared to the AM62A, which impacts embedded software development.
This adds dt bindings for TI's AM62D2 family of devices.
More details about the SoCs can be found in the Technical Reference Manual:

This reverts commit ad6b26b6a0a79166b53209df2ca1cf8636296382.
This commit introduces per-memcg/task NUMA balance statistics, but
unfortunately it introduced a NULL pointer exception due to the following
race condition: After a swap task candidate was chosen, its mm_struct
pointer was set to NULL due to task exit. Later, when performing the
actual task swapping, the p->mm caused the problem.
CPU0 CPU1
:
...
task_numa_migrate
task_numa_find_cpu
task_numa_compare
# a normal task p is chosen
env->best_task = p
# p exit:
exit_signals(p);
p->flags |= PF_EXITING
exit_mm
p->mm = NULL;
migrate_swap_stop
__migrate_swap_task((arg->src_task, arg->dst_cpu)
count_memcg_event_mm(p->mm, NUMA_TASK_SWAP)# p->mm is NULL
task_lock() should be held and the PF_EXITING flag needs to be checked to
prevent this from happening. After discussion, the conclusion was that
adding a lock is not worthwhile for some statistics calculations. Revert
the change and rely on the tracepoint for this purpose.

Some Broadcom PHYs are capable to operate in simplified MII mode,
without TXER, RXER, CRS and COL signals as defined for the MII.
The MII-Lite mode can be used on most Ethernet controllers with full
MII interface by just leaving the input signals (RXER, CRS, COL)
inactive. The absence of COL signal makes half-duplex link modes
impossible but does not interfere with BroadR-Reach link modes on
Broadcom PHYs, because they are all full-duplex only.
Add new interface type "mii-lite" to phy-connection-type enum.

Microchip Azurite ZL3073x represents chip family providing DPLL
and optionally PHC (PTP) functionality. The chips can be connected
be connected over I2C or SPI bus.
They have the following characteristics:
* up to 5 separate DPLL units (channels)
* 5 synthesizers
* 10 input pins (references)
* 10 outputs
* 20 output pins (output pin pair shares one output)
* Each reference and output can operate in either differential or
single-ended mode (differential mode uses 2 pins)
* Each output is connected to one of the synthesizers
* Each synthesizer is driven by one of the DPLL unit
The device uses 7-bit addresses and 8-bits values. It exposes 8-, 16-,
32- and 48-bits registers in address range <0x000,0x77F>. Due to 7bit
addressing, the range is organized into pages of 128 bytes, with each
page containing a page selector register at address 0x7F.
For reading/writing multi-byte registers, the device supports bulk
transfers.
Add basic functionality to access device registers, probe functionality
both I2C and SPI cases and add devlink support to provide info and
to set clock ID parameter.

Add a common DT schema for DPLL device and its associated pins.
The DPLL (device phase-locked loop) is a device used for precise clock
synchronization in networking and telecom hardware.
The device includes one or more DPLLs (channels) and one or more
physical input/output pins.
Each DPLL channel is used either to provide a pulse-per-clock signal or
to drive an Ethernet equipment clock.
The input and output pins have the following properties:
* label: specifies board label
* connection type: specifies its usage depending on wiring
* list of supported or allowed frequencies: depending on how the pin
is connected and where)
* embedded sync capability: indicates whether the pin supports this

Allow a guest to read the physical IA32_APERF and IA32_MPERF MSRs
without interception.
The IA32_APERF and IA32_MPERF MSRs are not virtualized. Writes are not
handled at all. The MSR values are not zeroed on vCPU creation, saved
on suspend, or restored on resume. No accommodation is made for
processor migration or for sharing a logical processor with other
tasks. No adjustments are made for non-unit TSC multipliers. The MSRs
do not account for time the same way as the comparable PMU events,
whether the PMU is virtualized by the traditional emulation method or
the new mediated pass-through approach.
Nonetheless, in a properly constrained environment, this capability
can be combined with a guest CPUID table that advertises support for
CPUID.6:ECX.APERFMPERF[bit 0] to induce a Linux guest to report the
effective physical CPU frequency in /proc/cpuinfo. Moreover, there is
no performance cost for this capability.

The common style in all bindings for enumerating similar variants is to
use 'enum', not 'oneOf', so all boards of same variant or using same SoM
should be grouped under enum. It is more readable, more compact and
makes easier to find actual devices from the same family/type. Also
there is completely no point to repeat the compatible in the description
(incircuit,icnova-a20-adb4006 implies this is "ICnova A20 ADB4006" and
pine64,pinephone-1.2 implies "Pine64 PinePhone (1.2)").
Combine two easily visible cases: ICnova A20 and Pine64 PinePhone.

Update the RSCI binding to support an optional secondary clock input on
the RZ/T2H SoC. At boot, the RSCI operates using the default synchronous
clock (PCLKM core clock), which is enabled by the bootloader. However, to
support a wider range of baud rates, the hardware also requires an
asynchronous external clock input. Clock selection is controlled
internally by the CCR3 register in the RSCI block.
Due to an incomplete understanding of the hardware, the original binding
defined only a single clock ("fck"), which is insufficient to describe the
full capabilities of the RSCI on RZ/T2H. This update corrects the binding
by allowing up to three clocks and defining the `clock-names` as
"operation", "bus", and optionally "sck" for the asynchronous clock input.
This is an ABI change, as it modifies the expected number and names of
clocks. However, since there are no in-kernel consumers of this binding
yet, the change is considered safe and non-disruptive.
Also remove the unneeded `serial0` alias from the DTS example and use
the R9A09G077_CLK_PCLKM macro for core clock.

The CMA heap's name in devtmpfs can vary depending on how the heap is
defined. Its name defaults to "reserved", but if a CMA area is defined
in the devicetree, the heap takes on the devicetree node's name, such as
"default-pool" or "linux,cma". To simplify naming, unconditionally name
it "default_cma_region", but keep a legacy node in place backed by the
same underlying allocator for backwards compatibility.

The PLPKS enabled PowerVM LPAR sysfs exposes all of the secure boot
secvars irrespective of the key management mode.
The PowerVM LPAR supports static and dynamic key management for secure
boot. The key management option can be updated in the management
console. The secvars PK, trustedcadb, and moduledb can be consumed both
in the static and dynamic key management modes for the loading of signed
third-party kernel modules. However, other secvars i.e. KEK, grubdb,
grubdbx, sbat, db and dbx, which are used to verify the grub and kernel
images, are consumed only in the dynamic key management mode.
Expose only PK, trustedcadb, and moduledb in the static key management
mode.

On a PLPKS enabled PowerVM LPAR, the secvar format property for static
key management is misrepresented as "ibm,plpks-sb-unknown", creating
reason for confusion.
Static key management mode uses fixed, built-in keys. Dynamic key
management mode allows keys to be updated in production to handle
security updates without firmware rebuilds.
Define a function named plpks_get_sb_keymgmt_mode() to retrieve the
key management mode based on the existence of the SB_VERSION property
in the firmware.
Set the secvar format property to either "ibm,plpks-sb-v<version>" or
"ibm,plpks-sb-v0" based on the key management mode, and return the
length of the secvar format property.
