cd845dfd46 RISC-V SoC drivers for v6.8
There's only one set of changes here, the addition of "Auto Update"
 support for PolarFire SoC. Auto Update is one of the ways that the FPGA
 bitstream can be updated, and the only one suitable for use from Linux
 as it does not immediately initiate a reboot when started.
 The driver was not accepted in the FPGA manager subsystem as the update
 only occurs after a reboot and makes no use of the FPGA manager
 framework.

0e034aec5b soc: fsl: cpm1: qmc: Extend the API to provide Rx status
In HDLC mode, some status flags related to the data read transfer can be
set by the hardware and need to be known by a QMC consumer for further
analysis.

Extend the API in order to provide these transfer status flags at the
read complete() call.

In TRANSPARENT mode, these flags have no meaning. Keep only one read
complete() API and update the consumers working in transparent mode.
In this case, the newly introduced flags parameter is simply unused.

fe3b082a6e memory: tegra: Add SID override programming for MC clients
For some devices the bootloader/firmware may set up the device in
bypass. Memory clients like display needs kernel to program SID after
resume because bootloader/firmware programs the SID of display device to
bypass. In order to make sure that kernel IOMMU mappings for these
devices work after resume, add SID override programming support for all
memory clients on memory controller resume.

This partially reverts 'commit ef86b2c280 ("memory: tegra: Remove
clients SID override programming")'

babe393974 The number of commits for documentation is not huge this time around, but
there are some significant changes nonetheless:
 
 - Some more Spanish-language and Chinese translations.
 
 - The much-discussed documentation of the confidential-computing threat
   model.
 
 - Powerpc and RISCV documentation move under Documentation/arch - these
   complete this particular bit of documentation churn.
 
 - A large traditional-Chinese documentation update.
 
 - A new document on backporting and conflict resolution.
 
 - Some kernel-doc and Sphinx fixes.
 
 Plus the usual smattering of smaller updates and typo fixes.

385903a7ec SoC driver updates for 6.7
The highlights for the driver support this time are
 
  - Qualcomm platforms gain support for the Qualcomm Secure Execution
    Environment firmware interface to access EFI variables on certain
    devices, and new features for multiple platform and firmware drivers.
 
  - Arm FF-A firmware support gains support for v1.1 specification features,
    in particular notification and memory transaction descriptor changes.
 
  - SCMI firmware support now support v3.2 features for clock and DVFS
    configuration and a new transport for Qualcomm platforms.
 
  - Minor cleanups and bugfixes are added to pretty much all the active
    platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
    atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
    In particular, this contains portions of the treewide conversion to
    use __counted_by annotations and the device_get_match_data helper.

The DFI is a unit which is suitable for measuring DDR utilization, but
so far it could only be used as an event driver for the DDR frequency
scaling driver. This adds perf support to the DFI driver.

Usage with the 'perf' tool can look like:

perf stat -a -e rockchip_ddr/cycles/,\
		rockchip_ddr/read-bytes/,\
		rockchip_ddr/write-bytes/,\
		rockchip_ddr/bytes/ sleep 1

           3595.90 MB   rockchip_ddr/bytes/

       1.014369709 seconds time elapsed

perf support has been tested on a RK3568 and a RK3399, the latter with
dual channel DDR.

ea608a01d4 firmware: tegra: Add suspend hook and reset BPMP IPC early on resume
Add suspend hook and a 'suspended' field in the 'struct tegra_bpmp'
to mark if BPMP is suspended. Also, add a 'flags' field in the
'struct tegra_bpmp_message' whose 'TEGRA_BPMP_MESSAGE_RESET' bit can be
set from the Tegra MC driver to signal that the reset of BPMP IPC
channels is required before sending MRQ to the BPMP FW. Together both
the fields allow us to handle any requests that might be sent too soon
as they can cause hang during system resume.

One case where we see BPMP requests being sent before the BPMP driver
has resumed is the memory bandwidth requests which are triggered by
onlining the CPUs during system resume. The CPUs are onlined before the
BPMP has resumed and we need to reset the BPMP IPC channels to handle
these requests.

The additional check for 'flags' is done to avoid any un-intended BPMP
IPC reset if the tegra_bpmp_transfer*() API gets called during suspend
sequence after the BPMP driver is suspended.

c462944901 iommu/tegra-gart: Remove tegra-gart
Thierry says this is not used anymore, and doesn't think it makes sense as
an iommu driver. The HW it supports is about 10 years old now and newer HW
uses different IOMMU drivers.

As this is the only driver with a GART approach, and it doesn't really
meet the driver expectations from the IOMMU core, let's just remove it
so we don't have to think about how to make it fit in.

It has a number of identified problems:
 - The assignment of iommu_groups doesn't match the HW behavior

 - It claims to have an UNMANAGED domain but it is really an IDENTITY
   domain with a translation aperture. This is inconsistent with the core
   expectation for security sensitive operations

 - It doesn't implement a SW page table under struct iommu_domain so
   * It can't accept a map until the domain is attached
   * It forgets about all maps after the domain is detached
   * It doesn't clear the HW of maps once the domain is detached
     (made worse by having the wrong groups)

f8fd5c2483 This pull request is full of clk driver changes. In fact, there aren't any
changes to the clk framework this time around. That's probably because everyone
 was on vacation (yours truly included). We did lose a couple clk drivers this
 time around because nobody was using those devices. That skews the diffstat a
 bit, but either way, nothing looks out of the ordinary here. The usual suspects
 are chugging along adding support for more SoCs and fixing bugs.
 
 If I had to choose, I'd say the theme for the past few months has been
 "polish". There's quite a few patches that migrate to
 devm_platform_ioremap_resource() in here. And there's more than a handful of
 patches that move the NR_CLKS define from the DT binding header to the driver.
 There's even patches that migrate drivers to use clk_parent_data and clk_hw to
 describe clk tree topology. It seems that the spring (summer?) cleaning bug got
 some folks, or the semiconductor shortage finally hit the software side.
 
 New Drivers:
  - StarFive JH7110 SoC clock drivers
  - Qualcomm IPQ5018 Global Clock Controller driver
  - Versa3 clk generator to support 48KHz playback/record with audio codec on
    RZ/G2L SMARC EVK
 
 Removed Drivers:
  - Remove non-OF mmp clk drivers
  - Remove OXNAS clk driver
 
 Updates:
  - Add __counted_by to struct clk_hw_onecell_data and struct spmi_pmic_div_clk_cc
  - Move defines for numbers of clks (NR_CLKS) from DT headers to drivers
  - Introduce kstrdup_and_replace() and use it
  - Add PLL rates for Rockchip rk3568
  - Add the display clock tree for Rockchip rv1126
  - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and RZ/G2 SoCs
  - Convert sun9i-mmc clock to use devm_platform_get_and_ioremap_resource()
  - Fix function name in a comment in ccu_mmc_timing.c
  - Parameter name correction for ccu_nkm_round_rate()
  - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e. consider alternative
    parent rates when determining clock rates
  - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
  - Support finding closest (as opposed to closest but not higher) clock rate
    for NM, NKM, mux and div type clocks, as use it for Allwinner A64 pll-video0
  - Prefer current parent rate if able to generate ideal clock rate for Allwinner NKM clocks
  - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks moved out to
    the interconnect drivers
  - Fix various PM runtime bugs across many Qualcomm clk drivers
  - Migrate Qualcomm MDM9615 is to parent_hw and parent_data
  - Add network related resets on Qualcomm IPQ4019
  - Add a couple missing USB related clocks to Qualcomm IPQ9574
  - Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock controller
  - In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs, and GPLL1 are
    added, while PCIe pipe clock, SDCC rcg ops are corrected

Pull clk subsystem updates from Stephen Boyd:
 "This pull request is full of clk driver changes. In fact, there aren't
  any changes to the clk framework this time around. That's probably
  because everyone was on vacation (yours truly included). We did lose a
  couple clk drivers this time around because nobody was using those
  devices. That skews the diffstat a bit, but either way, nothing looks
  out of the ordinary here. The usual suspects are chugging along adding
  support for more SoCs and fixing bugs.

  If I had to choose, I'd say the theme for the past few months has been
  "polish". There's quite a few patches that migrate to
  devm_platform_ioremap_resource() in here. And there's more than a
  handful of patches that move the NR_CLKS define from the DT binding
  header to the driver. There's even patches that migrate drivers to use
  clk_parent_data and clk_hw to describe clk tree topology. It seems
  that the spring (summer?) cleaning bug got some folks, or the
  semiconductor shortage finally hit the software side.

  New Drivers:
   - StarFive JH7110 SoC clock drivers
   - Qualcomm IPQ5018 Global Clock Controller driver
   - Versa3 clk generator to support 48KHz playback/record with audio
     codec on RZ/G2L SMARC EVK

  Removed Drivers:
   - Remove non-OF mmp clk drivers
   - Remove OXNAS clk driver

  Updates:
   - Add __counted_by to struct clk_hw_onecell_data and struct
     spmi_pmic_div_clk_cc
   - Move defines for numbers of clks (NR_CLKS) from DT headers to
     drivers
   - Introduce kstrdup_and_replace() and use it
   - Add PLL rates for Rockchip rk3568
   - Add the display clock tree for Rockchip rv1126
   - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and
     RZ/G2 SoCs
   - Convert sun9i-mmc clock to use
     devm_platform_get_and_ioremap_resource()
   - Fix function name in a comment in ccu_mmc_timing.c
   - Parameter name correction for ccu_nkm_round_rate()
   - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e.
     consider alternative parent rates when determining clock rates
   - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
   - Support finding closest (as opposed to closest but not higher)
     clock rate for NM, NKM, mux and div type clocks, as use it for
     Allwinner A64 pll-video0
   - Prefer current parent rate if able to generate ideal clock rate for
     Allwinner NKM clocks
   - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks
     moved out to the interconnect drivers
   - Fix various PM runtime bugs across many Qualcomm clk drivers
   - Migrate Qualcomm MDM9615 is to parent_hw and parent_data
   - Add network related resets on Qualcomm IPQ4019
   - Add a couple missing USB related clocks to Qualcomm IPQ9574
   - Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock
     controller
   - In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs,
     and GPLL1 are added, while PCIe pipe clock, SDCC rcg ops are
     corrected
   - Add missing GDSCs to and correct GDSCs for the SC8280XP global
     clock controller driver
   - Support retention for the Qualcomm SC8280XP display clock
     controller GDSCs.
   - Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE
     to fix issues with missing parent clocks across sc7180, sm7150,

d1478aea64 memory: tegra: Add dummy implementation on Tegra194
With the introduction of commit 9365bf006f ("PCI: tegra194: Add
interconnect support in Tegra234"), the PCI driver on Tegra194 and later
requires an interconnect provider. However, a provider is currently only
exposed on Tegra234 and this causes PCI on Tegra194 to defer probe
indefinitely.

Fix this by adding a dummy implementation on Tegra194. This allows nodes
to be provided to interconnect consumers, but doesn't do any bandwidth
accounting or frequency scaling.

Fixes: 9365bf006f ("PCI: tegra194: Add interconnect support in Tegra234")

c60819149b net: dsa: felix: make vsc9959_tas_guard_bands_update() visible to ocelot->ops
In a future change we will need to make
ocelot_port_update_active_preemptible_tcs() call
vsc9959_tas_guard_bands_update(), but that is currently not possible,
since the ocelot switch lib does not have access to functions private to
the DSA wrapper.

Move the pointer to vsc9959_tas_guard_bands_update() from felix->info
(which is private to the DSA driver) to ocelot->ops (which is also
visible to the ocelot switch lib).

009d30f1a7 net: mscc: ocelot: extend ocelot->fwd_domain_lock to cover ocelot->tas_lock
In a future commit we will have to call vsc9959_tas_guard_bands_update()
from ocelot_port_update_active_preemptible_tcs(), and that will be
impossible due to the AB/BA locking dependencies between
ocelot->tas_lock and ocelot->fwd_domain_lock.

Just like we did in commit 3ff468ef98 ("net: mscc: ocelot: remove
struct ocelot_mm_state :: lock"), the only solution is to expand the
scope of ocelot->fwd_domain_lock for it to also serialize changes made
to the Time-Aware Shaper, because those will have to result in a
recalculation of cut-through TCs, which is something that depends on the
forwarding domain.

45d0fcb5bc net: mscc: ocelot: don't keep PTP configuration of all ports in single structure
In a future change, the driver will need to determine whether PTP RX
timestamping is enabled on a port (including whether traps were set up
on that port in particular) and that is currently not possible.

The driver supports different RX filters (L2, L4) and kinds of TX
timestamping (one-step, two-step) on its ports, but it saves all
configuration in a single struct hwtstamp_config that is global to the
switch. So, the latest timestamping configuration on one port
(including a request to disable timestamping) affects what gets reported
for all ports, even though the configuration itself is still individual
to each port.

The port timestamping configurations are only coupled because of the
common structure, so replace the hwtstamp_config with a mask of trapped
protocols saved per port. We also have the ptp_cmd to distinguish
between one-step and two-step PTP timestamping, so with those 2 bits of
information we can fully reconstruct a descriptive struct
hwtstamp_config for each port, during the SIOCGHWTSTAMP ioctl.

Make CPU cluster's bandwidth (BW) request a multiple of MC channels.
CPU OPP tables have BW info per MC channel. But, the actual BW depends
on the number of MC channels which can change as per the boot config.
Get the number of MC channels which are actually enabled in current
boot configuration and multiply the BW request from a CPU cluster with
the number of enabled MC channels. This is not required to be done for
other MC clients.

Add Interconnect framework support to dynamically set the DRAM
bandwidth from different clients. Both the MC and EMC drivers are
added as ICC providers. The path for any request is:
 MC-Client[1-n] -> MC -> EMC -> EMEM/DRAM

MC client's request for bandwidth will go to the MC driver which
passes the client request info like BPMP Client ID, Client type
and the Bandwidth to the BPMP-FW. The final DRAM freq to achieve
the requested bandwidth is set by the BPMP-FW based on the passed
parameters.

e81507acdc Nothing looks out of the ordinary in this batch of clk driver updates. There
are a couple patches to the core clk framework, but they're all basically
 cleanups or debugging aids. The driver updates and new additions are dominated
 in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of
 new drivers for various SoCs, and MediaTek gained a bunch of drivers for
 MT8188. The MediaTek drivers are being modernized as well, so there are
 updates all over that vendor's clk drivers. There's also a couple other new clk
 drivers in here, for example the Starfive JH7110 SoC support is added.
 
 Outside of the two major SoC vendors though, we have the usual collection of
 non-critical fixes and cleanups to various clk drivers. It's good to see that
 we're getting more cleanups and modernization patches. Maybe one day we'll be
 able to properly split clk providers from clk consumers.
 
 Core:
  - Print an informational message before disabling unused clks
 
 New Drivers:
  - BCM63268 timer clock and reset controller
  - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
    MT8195 SoCs
  - Mediatek MT8188 SoC clk drivers
  - Clock driver for Sunplus SP7021 SoC
  - Clk driver support for Loongson-2 SoCs
  - Clock driver for Skyworks Si521xx I2C PCIe clock generators
  - Initial Starfive JH7110 clk/reset support
  - Global clock controller drivers for Qualcomm SM7150, IPQ9574, MSM8917 and IPQ5332 SoCs
  - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P SoCs
 
 Updates:
  - Shrink size of clk_fractional_divider a little
  - Convert various clk drivers to devm_of_clk_add_hw_provider()
  - Convert platform clk drivers to remove_new()
  - Converted most Mediatek clock drivers to struct platform_driver
  - MediaTek clock drivers can be built as modules
  - Reimplement Loongson-1 clk driver with DT support
  - Migrate socfpga clk driver to of_clk_add_hw_provider()
  - Support for i3c clks on Aspeed ast2600 SoCs
  - Add clock generic devm_clk_hw_register_gate_parent_data
  - Add audiomix block control for i.MX8MP
  - Add support for determine_rate to i.MX composite-8m
  - Let the LCDIF Pixel clock of i.MX8MM and i.MX8MN set parent rate
  - Provide clock name in error message for clk-gpr-mux on get parent failure
  - Drop duplicate imx_clk_mux_flags macro
  - Register the i.MX8MP Media Disp2 Pix clock as bus clock
  - Add Media LDB root clock to i.MX8MP
  - Make i.MX8MP nand_usdhc_bus clock as non-critical
  - Fix the rate table for i.MX fracn-gppll
  - Disable HW control for the fracn-gppll in order to be controlled by

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "Nothing looks out of the ordinary in this batch of clk driver updates.

  There are a couple patches to the core clk framework, but they're all
  basically cleanups or debugging aids. The driver updates and new
  additions are dominated in the diffstat by Qualcomm and MediaTek
  drivers. Qualcomm gained a handful of new drivers for various SoCs,
  and MediaTek gained a bunch of drivers for MT8188. The MediaTek
  drivers are being modernized as well, so there are updates all over
  that vendor's clk drivers. There's also a couple other new clk drivers
  in here, for example the Starfive JH7110 SoC support is added.

  Outside of the two major SoC vendors though, we have the usual
  collection of non-critical fixes and cleanups to various clk drivers.
  It's good to see that we're getting more cleanups and modernization
  patches. Maybe one day we'll be able to properly split clk providers
  from clk consumers.

  Core:
   - Print an informational message before disabling unused clks

  New Drivers:
   - BCM63268 timer clock and reset controller
   - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
     MT8195 SoCs
   - Mediatek MT8188 SoC clk drivers
   - Clock driver for Sunplus SP7021 SoC
   - Clk driver support for Loongson-2 SoCs
   - Clock driver for Skyworks Si521xx I2C PCIe clock generators
   - Initial Starfive JH7110 clk/reset support
   - Global clock controller drivers for Qualcomm SM7150, IPQ9574,
     MSM8917 and IPQ5332 SoCs
   - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P
     SoCs

  Updates:
   - Shrink size of clk_fractional_divider a little
   - Convert various clk drivers to devm_of_clk_add_hw_provider()
   - Convert platform clk drivers to remove_new()
   - Converted most Mediatek clock drivers to struct platform_driver
   - MediaTek clock drivers can be built as modules
   - Reimplement Loongson-1 clk driver with DT support
   - Migrate socfpga clk driver to of_clk_add_hw_provider()

   - Add clock generic devm_clk_hw_register_gate_parent_data
   - Add audiomix block control for i.MX8MP
   - Add support for determine_rate to i.MX composite-8m
   - Let the LCDIF Pixel clock of i.MX8MM and i.MX8MN set parent rate
   - Provide clock name in error message for clk-gpr-mux on get parent
     failure
   - Drop duplicate imx_clk_mux_flags macro
   - Register the i.MX8MP Media Disp2 Pix clock as bus clock
   - Add Media LDB root clock to i.MX8MP
   - Make i.MX8MP nand_usdhc_bus clock as non-critical
   - Fix the rate table for i.MX fracn-gppll

1c15ca4e4e sound updates for 6.4-rc1
At this time, it's an interesting mixture of changes for both old and
 new stuff.  Majority of changes are about ASoC (lots of systematic
 changes for converting remove callbacks to void, and cleanups), while
 we got the fixes and the enhancements of very old PCI cards, too.
 
 Here are some highlights:
 
 ALSA/ASoC Core:
 - Continued effort of more ASoC core cleanups
 - Minor improvements for XRUN handling in indirect PCM helpers
 - Code refactoring of PCM core code
 
 ASoC:
 - Continued feature and simplification work on SOF, including addition
   of a no-DSP mode for bringup, HDA MLink and extensions to the IPC4
   protocol
 - Hibernation support for CS35L45
 - More DT binding conversions
 - Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363,
   nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas R-Car
   Gen4, Rockchip RK3588 and TI TAS5733
 
 ALSA:
 - Lots of works for legacy emu10k1 and ymfpci PCI drivers
 - PCM kselftest fixes and enhancements

Linus Torvalds
6e98b09da9 Networking changes for 6.4.
Core
 ----
 
  - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
    default value allows for better BIG TCP performances.
 
  - Reduce compound page head access for zero-copy data transfers.
 
  - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
 
  - Threaded NAPI improvements, adding defer skb free support and unneeded
    softirq avoidance.
 
  - Address dst_entry reference count scalability issues, via false
    sharing avoidance and optimize refcount tracking.
 
  - Add lockless accesses annotation to sk_err[_soft].
 
  - Optimize again the skb struct layout.
 
  - Extends the skb drop reasons to make it usable by multiple
    subsystems.
 
  - Better const qualifier awareness for socket casts.
 
 BPF
 ---
 
  - Add skb and XDP typed dynptrs which allow BPF programs for more
    ergonomic and less brittle iteration through data and variable-sized
    accesses.
 
  - Add a new BPF netfilter program type and minimal support to hook
    BPF programs to netfilter hooks such as prerouting or forward.
 
  - Add more precise memory usage reporting for all BPF map types.
 
  - Adds support for using {FOU,GUE} encap with an ipip device operating
    in collect_md mode and add a set of BPF kfuncs for controlling encap
    params.
 
  - Allow BPF programs to detect at load time whether a particular kfunc
    exists or not, and also add support for this in light skeleton.
 
  - Bigger batch of BPF verifier improvements to prepare for upcoming BPF
    open-coded iterators allowing for less restrictive looping capabilities.
 
  - Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
    programs to NULL-check before passing such pointers into kfunc.
 
  - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
    local storage maps.
 
  - Enable RCU semantics for task BPF kptrs and allow referenced kptr
    tasks to be stored in BPF maps.
 
  - Add support for refcounted local kptrs to the verifier for allowing
    shared ownership, useful for adding a node to both the BPF list and
    rbtree.
 
  - Add BPF verifier support for ST instructions in convert_ctx_access()
    which will help new -mcpu=v4 clang flag to start emitting them.
 
  - Add ARM32 USDT support to libbpf.
 
  - Improve bpftool's visual program dump which produces the control
    flow graph in a DOT format by adding C source inline annotations.
 
 Protocols
 ---------
 
  - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
    indicates the provenance of the IP address.
 
  - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
 
  - Add the handshake upcall mechanism, allowing the user-space
    to implement generic TLS handshake on kernel's behalf.
 
  - Bridge: support per-{Port, VLAN} neighbor suppression, increasing
    resilience to nodes failures.
 
  - SCTP: add support for Fair Capacity and Weighted Fair Queueing
    schedulers.
 
  - MPTCP: delay first subflow allocation up to its first usage. This
    will allow for later better LSM interaction.
 
  - xfrm: Remove inner/outer modes from input/output path. These are
    not needed anymore.
 
  - WiFi:
    - reduced neighbor report (RNR) handling for AP mode
    - HW timestamping support
    - support for randomized auth/deauth TA for PASN privacy
    - per-link debugfs for multi-link
    - TC offload support for mac80211 drivers
    - mac80211 mesh fast-xmit and fast-rx support
    - enable Wi-Fi 7 (EHT) mesh support
 
 Netfilter
 ---------
 
  - Add nf_tables 'brouting' support, to force a packet to be routed
    instead of being bridged.
 
  - Update bridge netfilter and ovs conntrack helpers to handle
    IPv6 Jumbo packets properly, i.e. fetch the packet length
    from hop-by-hop extension header. This is needed for BIT TCP
    support.
 
  - The iptables 32bit compat interface isn't compiled in by default
    anymore.
 
  - Move ip(6)tables builtin icmp matches to the udptcp one.
    This has the advantage that icmp/icmpv6 match doesn't load the
    iptables/ip6tables modules anymore when iptables-nft is used.
 
  - Extended netlink error report for netdevice in flowtables and
    netdev/chains. Allow for incrementally add/delete devices to netdev
    basechain. Allow to create netdev chain without device.
 
 Driver API
 ----------
 
  - Remove redundant Device Control Error Reporting Enable, as PCI core
    has already error reporting enabled at enumeration time.
 
  - Move Multicast DB netlink handlers to core, allowing devices other
    then bridge to use them.
 
  - Allow the page_pool to directly recycle the pages from safely
    localized NAPI.
 
  - Implement lockless TX queue stop/wake combo macros, allowing for
    further code de-duplication and sanitization.
 
  - Add YNL support for user headers and struct attrs.
 
  - Add partial YNL specification for devlink.
 
  - Add partial YNL specification for ethtool.
 
  - Add tc-mqprio and tc-taprio support for preemptible traffic classes.
 
  - Add tx push buf len param to ethtool, specifies the maximum number
    of bytes of a transmitted packet a driver can push directly to the
    underlying device.
 
  - Add basic LED support for switch/phy.
 
  - Add NAPI documentation, stop relaying on external links.
 
  - Convert dsa_master_ioctl() to netdev notifier. This is a preparatory
    work to make the hardware timestamping layer selectable by user
    space.
 
  - Add transceiver support and improve the error messages for CAN-FD
    controllers.
 
 New hardware / drivers

  - Ethernet:
    - AMD/Pensando core device support
    - MediaTek MT7981 SoC

Merge tag 'net-next-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
 "Core:

   - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
     default value allows for better BIG TCP performances

   - Reduce compound page head access for zero-copy data transfers

   - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
     possible

   - Threaded NAPI improvements, adding defer skb free support and
     unneeded softirq avoidance

   - Address dst_entry reference count scalability issues, via false
     sharing avoidance and optimize refcount tracking

   - Add lockless accesses annotation to sk_err[_soft]

   - Optimize again the skb struct layout

   - Extends the skb drop reasons to make it usable by multiple
     subsystems

   - Better const qualifier awareness for socket casts

  BPF:

   - Add skb and XDP typed dynptrs which allow BPF programs for more
     ergonomic and less brittle iteration through data and
     variable-sized accesses

   - Add a new BPF netfilter program type and minimal support to hook
     BPF programs to netfilter hooks such as prerouting or forward

   - Add more precise memory usage reporting for all BPF map types

   - Adds support for using {FOU,GUE} encap with an ipip device
     operating in collect_md mode and add a set of BPF kfuncs for
     controlling encap params

   - Allow BPF programs to detect at load time whether a particular
     kfunc exists or not, and also add support for this in light
     skeleton

   - Bigger batch of BPF verifier improvements to prepare for upcoming
     BPF open-coded iterators allowing for less restrictive looping
     capabilities

   - Rework RCU enforcement in the verifier, add kptr_rcu and enforce
     BPF programs to NULL-check before passing such pointers into kfunc

   - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
     in local storage maps

   - Enable RCU semantics for task BPF kptrs and allow referenced kptr
     tasks to be stored in BPF maps

   - Add support for refcounted local kptrs to the verifier for allowing
     shared ownership, useful for adding a node to both the BPF list and
     rbtree

   - Add BPF verifier support for ST instructions in
     convert_ctx_access() which will help new -mcpu=v4 clang flag to
     start emitting them

   - Add ARM32 USDT support to libbpf

   - Improve bpftool's visual program dump which produces the control
     flow graph in a DOT format by adding C source inline annotations

  Protocols:

   - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
     indicates the provenance of the IP address

   - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition

   - Add the handshake upcall mechanism, allowing the user-space to
     implement generic TLS handshake on kernel's behalf

   - Bridge: support per-{Port, VLAN} neighbor suppression, increasing
     resilience to nodes failures

   - SCTP: add support for Fair Capacity and Weighted Fair Queueing
     schedulers

   - MPTCP: delay first subflow allocation up to its first usage. This
     will allow for later better LSM interaction

   - xfrm: Remove inner/outer modes from input/output path. These are
     not needed anymore

   - WiFi:
      - reduced neighbor report (RNR) handling for AP mode
      - HW timestamping support
      - support for randomized auth/deauth TA for PASN privacy
      - per-link debugfs for multi-link
      - TC offload support for mac80211 drivers
      - mac80211 mesh fast-xmit and fast-rx support
      - enable Wi-Fi 7 (EHT) mesh support

  Netfilter:

   - Add nf_tables 'brouting' support, to force a packet to be routed
     instead of being bridged

   - Update bridge netfilter and ovs conntrack helpers to handle IPv6
     Jumbo packets properly, i.e. fetch the packet length from
     hop-by-hop extension header. This is needed for BIT TCP support

   - The iptables 32bit compat interface isn't compiled in by default
     anymore

   - Move ip(6)tables builtin icmp matches to the udptcp one. This has
     the advantage that icmp/icmpv6 match doesn't load the
     iptables/ip6tables modules anymore when iptables-nft is used

   - Extended netlink error report for netdevice in flowtables and
     netdev/chains. Allow for incrementally add/delete devices to netdev
     basechain. Allow to create netdev chain without device

  Driver API:

   - Remove redundant Device Control Error Reporting Enable, as PCI core
     has already error reporting enabled at enumeration time

   - Move Multicast DB netlink handlers to core, allowing devices other
     then bridge to use them

   - Allow the page_pool to directly recycle the pages from safely
     localized NAPI

   - Implement lockless TX queue stop/wake combo macros, allowing for
     further code de-duplication and sanitization

   - Add YNL support for user headers and struct attrs

   - Add partial YNL specification for devlink

   - Add partial YNL specification for ethtool

   - Add tc-mqprio and tc-taprio support for preemptible traffic classes

   - Add tx push buf len param to ethtool, specifies the maximum number
     of bytes of a transmitted packet a driver can push directly to the
     underlying device

   - Add basic LED support for switch/phy

   - Add NAPI documentation, stop relaying on external links

   - Convert dsa_master_ioctl() to netdev notifier. This is a
     preparatory work to make the hardware timestamping layer selectable
     by user space

   - Add transceiver support and improve the error messages for CAN-FD
     controllers

f68a40ee47 clocksource/drivers/timer-imx-gpt: Remove non-DT function
mxc_timer_init() was originally only used by non-DT i.MX platforms.

i.MX has already been converted to be a DT-only platform.

Remove the unused mxc_timer_init() function.

403ffc2c34 net: mscc: ocelot: add support for preemptible traffic classes
In order to not transmit (preemptible) frames which will be received by
the link partner as corrupted (because it doesn't support FP), the
hardware requires the driver to program the QSYS_PREEMPTION_CFG_P_QUEUES
register only after the MAC Merge layer becomes active (verification
succeeds, or was disabled).

There are some cases when FP is known (through experimentation) to be
broken. Give priority to FP over cut-through switching, and disable FP
for known broken link modes.

aac80140dc net: mscc: ocelot: add support for mqprio offload
This doesn't apply anything to hardware and in general doesn't do
anything that the software variant doesn't do, except for checking that
there isn't more than 1 TXQ per TC (TXQs for a DSA switch are a dubious
concept anyway). The reason we add this is to be able to parse one more
field added to struct tc_mqprio_qopt_offload, namely preemptible_tcs.

7bf4a5b071 net: mscc: ocelot: optimize ocelot_mm_irq()
The MAC Merge IRQ of all ports is shared with the PTP TX timestamp IRQ
of all ports, which means that currently, when a PTP TX timestamp is
generated, felix_irq_handler() also polls for the MAC Merge layer status
of all ports, looking for changes. This makes the kernel do more work,
and under certain circumstances may make ptp4l require a
tx_timestamp_timeout argument higher than before.

Changes to the MAC Merge layer status are only to be expected under
certain conditions - its TX direction needs to be enabled - so we can
check early if that is the case, and omit register access otherwise.

Make ocelot_mm_update_port_status() skip register access if
mm->tx_enabled is unset, and also call it once more, outside IRQ
context, from ocelot_port_set_mm(), when mm->tx_enabled transitions from
true to false, because an IRQ is also expected in that case.

Also, a port may have its MAC Merge layer enabled but it may not have
generated the interrupt. In that case, there's no point in writing to
DEV_MM_STATUS to acknowledge that IRQ. We can reduce the number of
register writes per port with MM enabled by keeping an "ack" variable
which writes the "write-one-to-clear" bits. Those are 3 in number:
PRMPT_ACTIVE_STICKY, UNEXP_RX_PFRM_STICKY and UNEXP_TX_PFRM_STICKY.
The other fields in DEV_MM_STATUS are read-only and it doesn't matter
what is written to them, so writing zero is just fine.
