d57ee99831 net: ethernet: mtk_wed: annotate RCU release in attach() 
There are some sparse warnings in wifi, and it seems that
it's actually possible to annotate a function pointer with
__releases(), making the sparse warnings go away. In a way
that also serves as documentation that rcu_read_unlock()
must be called in the attach method, so add that annotation.

14d0e1a09f soc: driver updates for 6.12 
Nothing particular important in the SoC driver updates, just the usual
 improvements to for drivers/soc and a couple of subsystems that don't
 fit anywhere else:
 
  - The largest set of updates is for Qualcomm SoC drivers, extending the
    set of supported features for additional SoCs in the QSEECOM, LLCC
    and socinfo drivers.a
 
  - The ti_sci firmware driver gains support for power managment
 
  - The drivers/reset subsystem sees a rework of the microchip
    sparx5 and amlogic reset drivers to support additional chips,
    plus a few minor updates on other platforms
 
  - The SCMI firmware interface driver gains support for two protocol
    extensions, allowing more flexible use of the shared memory area
    and new DT binding properties for configurability.
 
  - Mediatek SoC drivers gain support for power managment on the MT8188
    SoC and a new driver for DVFS.
 
  - The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
    and a few bugfixes
 
  - The Hisilicon Kunpeng HCCS driver gains support for configuring
    lanes through sysfs
 
 Finally, there are cleanups and minor fixes for drivers/soc, drivers/bus,
 and drivers/memory, including changing back the .remove_new callback
 to .remove, as well as a few other updates for freescale (powerpc)
 soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory
 controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers

soc: mediatek: Add MediaTek DVFS Resource Collector (DVFSRC) driver 
The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a
Hardware module used to collect all the requests from both software and the
various remote processors embedded into the SoC and decide about a minimum
operating voltage and a minimum DRAM frequency to fulfill those requests in
an effort to provide the best achievable performance per watt.

This hardware IP is capable of transparently performing direct register R/W
on all of the DVFSRC-controlled regulators and SoC bandwidth knobs.

This driver includes support for MT8183, MT8192 and MT8195.

soc: mediatek: mtk-cmdq: Add cmdq_pkt_acquire_event() function 
Add cmdq_pkt_acquire_event() function to support CMDQ user making
an instruction for acquiring event.

CMDQ users can use cmdq_pkt_acquire_event() as `mutex_lock`
and cmdq_pkt_clear_event() as `mutex_unlock` to protect the global
resource modified instructions between them.

cmdq_pkt_acquire_event() would wait for event to be cleared.
After event is cleared by cmdq_pkt_clear_event() in other GCE threads,
cmdq_pkt_acquire_event() would set event and keep executing next
instruction. So the mutex would work like this:

    cmdq_pkt_acquire_event() /* mutex lock */

    /* critical secton instructions that modified global resource */

    cmdq_pkt_clear_event() /* mutex unlock */

Prevent the critical section instructions from being affected by other
GCE threads.

Add cmdq_pkt_poll_addr function to support CMDQ user making
an instruction for polling a specific address of hardware rigster
to check the value with or without mask.

POLL is a legacy operation in GCE, so it does not support SPR and
CMDQ_CODE_LOGIC. To support polling the register address which doesn't
have the subsys id, CMDQ users need to make an instruction with GPR and
CMDQ_CODE_MASK operation to move the register address to be poll into GPR.
Then users can make an POLL instruction with GPR to poll the register
address assigned in previous instruction.

ff0ea57fa3 net: ethernet: mtk_wed: introduce mtk_wed_buf structure 
Introduce mtk_wed_buf structure to store both virtual and physical
addresses allocated in mtk_wed_tx_buffer_alloc() routine. This is a
preliminary patch to add WED support for MT7988 SoC since it relies on a
different dma descriptor layout not storing page dma addresses.

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.

05f3ab7780 net: ethernet: mtk_eth_soc: add code for offloading flows from wlan devices 
WED version 2 (on MT7986 and later) can offload flows originating from
wireless devices.
In order to make that work, ndo_setup_tc needs to be implemented on the
netdevs. This adds the required code to offload flows coming in from WED,
while keeping track of the incoming wed index used for selecting the
correct PPE device.

As usual, there are lots of minor driver changes across SoC platforms
 from  NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
 These usually add support for additional chip variations in existing
 drivers, but also add features or bugfixes.
 
 The SCMI firmware subsystem gains a unified raw userspace interface
 through debugfs, which can be used for validation purposes.
 
 Newly added drivers include:
 
  - New power management drivers for StarFive JH7110, Allwinner D1 and
    Renesas RZ/V2M
 
  - A driver for Qualcomm battery and power supply status
 
  - A SoC device driver for identifying Nuvoton WPCM450 chips

8af1f6b5bc soc: mediatek: add cmdq support of mtk-mmsys config API for mt8195 vdosys1 
Add cmdq support for mtk-mmsys config API.
The mmsys config register settings need to take effect with the other
HW settings(like OVL_ADAPTOR...) at the same vblanking time.

If we use CPU to write the mmsys reg, we can't guarantee all the
settings can be written in the same vblanking time.
Cmdq is used for this purpose. We prepare all the related HW settings
in one cmdq packet. The first command in the packet is "wait stream done",
and then following with all the HW settings. After the cmdq packet is
flush to GCE HW. The GCE waits for the "stream done event" to coming
and then starts flushing all the HW settings. This can guarantee all
the settings flush in the same vblanking.

First set of patches for v6.3. The most important change here is that

 Wi-Fi 7 devices at all. We also added a warning if anyone with modern
 drivers (ie. cfg80211 and mac80211 drivers) tries to use Wireless
 Extensions, everyone should switch to using nl80211 interface instead.
 
 Static WEP support is removed, there wasn't any driver using that
 anyway so there's no user impact. Otherwise it's smaller features and
 fixes as usual.
 
 Note: As mt76 had tricky conflicts due to the fixes in wireless tree,
 we decided to merge wireless into wireless-next to solve them easily.
 There should not be any merge problems anymore.
 
 Major changes:
 
 cfg80211
 
 * remove never used static WEP support
 
 * warn if Wireless Extention interface is used with cfg80211/mac80211 drivers
 
 * stop supporting Wireless Extensions with Wi-Fi 7 devices
 
 * support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting

Linus Torvalds
7e68dd7d07 Networking changes for 6.2. 
Core
 ----
  - Allow live renaming when an interface is up
 
  - Add retpoline wrappers for tc, improving considerably the
    performances of complex queue discipline configurations.
 
  - Add inet drop monitor support.
 
  - A few GRO performance improvements.
 
  - Add infrastructure for atomic dev stats, addressing long standing
    data races.
 
  - De-duplicate common code between OVS and conntrack offloading
    infrastructure.
 
  - A bunch of UBSAN_BOUNDS/FORTIFY_SOURCE improvements.
 
  - Netfilter: introduce packet parser for tunneled packets
 
  - Replace IPVS timer-based estimators with kthreads to scale up
    the workload with the number of available CPUs.
 
  - Add the helper support for connection-tracking OVS offload.
 
 BPF
 ---
  - Support for user defined BPF objects: the use case is to allocate
    own objects, build own object hierarchies and use the building
    blocks to build own data structures flexibly, for example, linked
    lists in BPF.
 
  - Make cgroup local storage available to non-cgroup attached BPF
    programs.
 
  - Avoid unnecessary deadlock detection and failures wrt BPF task
    storage helpers.
 
  - A relevant bunch of BPF verifier fixes and improvements.
 
  - Veristat tool improvements to support custom filtering, sorting,
    and replay of results.
 
  - Add LLVM disassembler as default library for dumping JITed code.
 
  - Lots of new BPF documentation for various BPF maps.
 
  - Add bpf_rcu_read_{,un}lock() support for sleepable programs.
 
  - Add RCU grace period chaining to BPF to wait for the completion
    of access from both sleepable and non-sleepable BPF programs.
 
  - Add support storing struct task_struct objects as kptrs in maps.
 
  - Improve helper UAPI by explicitly defining BPF_FUNC_xxx integer
    values.
 
  - Add libbpf *_opts API-variants for bpf_*_get_fd_by_id() functions.
 
 Protocols
 ---------
  - TCP: implement Protective Load Balancing across switch links.
 
  - TCP: allow dynamically disabling TCP-MD5 static key, reverting
    back to fast[er]-path.
 
  - UDP: Introduce optional per-netns hash lookup table.
 
  - IPv6: simplify and cleanup sockets disposal.
 
  - Netlink: support different type policies for each generic
    netlink operation.
 
  - MPTCP: add MSG_FASTOPEN and FastOpen listener side support.
 
  - MPTCP: add netlink notification support for listener sockets
    events.
 
  - SCTP: add VRF support, allowing sctp sockets binding to VRF
    devices.
 
  - Add bridging MAC Authentication Bypass (MAB) support.
 
  - Extensions for Ethernet VPN bridging implementation to better
    support multicast scenarios.
 
  - More work for Wi-Fi 7 support, comprising conversion of all
    the existing drivers to internal TX queue usage.
 
  - IPSec: introduce a new offload type (packet offload) allowing
    complete header processing and crypto offloading.
 
  - IPSec: extended ack support for more descriptive XFRM error
    reporting.
 
  - RXRPC: increase SACK table size and move processing into a
    per-local endpoint kernel thread, reducing considerably the
    required locking.
 
  - IEEE 802154: synchronous send frame and extended filtering

e6c7e6216d soc: mediatek: Add all settings to mtk_mmsys_ddp_dpi_fmt_config func 
The difference between MT8186 and other ICs is that when modifying the
output format, we need to modify the mmsys_base+0x400 register to take
effect. So when setting the dpi output format, we need to call
mtk_mmsys_ddp_dpi_fmt_config to set it to MT8186 synchronously.

Commit a071e52f75d1 ("soc: mediatek: Add mmsys func to adapt to dpi
output for MT8186") lacked some of the possible output formats and also
had a wrong bitmask.

Add the missing output formats and fix the bitmask.

While at it, also update mtk_mmsys_ddp_dpi_fmt_config() to use generic
formats, so that it is slightly easier to extend for other platforms.

ff6862c23d ARM: driver updates for 6.1 
The drivers branch for 6.1 is a bit larger than for most releases.  Most
 of the changes come from SoC maintainers for the drivers/soc subsystem:
 
  - A new driver for error handling on the NVIDIA Tegra
    'control backbone' bus.
 
  - A new driver for Qualcomm LLCC/DDR bandwidth measurement
 
  - New Rockchip rv1126 and rk3588 power domain drivers
 
  - DT binding updates for memory controllers, older Rockchip
    SoCs, various Mediatek devices, Qualcomm SCM firmware
 
  - Minor updates to Hisilicon LPC bus, the Allwinner SRAM
    driver, the Apple rtkit firmware driver, Tegra firmware
 
  - Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
    Tegra, Qualcomm, Broadcom, NXP, ...)
 
 There are also some separate subsystem with downstream maintainers that
 merge updates this way:
 
  - Various updates and new drivers in the memory controller
    subsystem for Mediatek and Broadcom SoCs
 
  - Small set of changes in preparation to add support for FF-A
    v1.1 specification later, in the Arm FF-A firmware subsystem
 
  - debugfs support in the PSCI firmware subsystem

Merge tag 'arm-drivers-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM driver updates from Arnd Bergmann:
 "The drivers branch for 6.1 is a bit larger than for most releases.

  Most of the changes come from SoC maintainers for the drivers/soc
  subsystem:

   - A new driver for error handling on the NVIDIA Tegra 'control
     backbone' bus.

   - A new driver for Qualcomm LLCC/DDR bandwidth measurement

   - New Rockchip rv1126 and rk3588 power domain drivers

   - DT binding updates for memory controllers, older Rockchip SoCs,
     various Mediatek devices, Qualcomm SCM firmware

   - Minor updates to Hisilicon LPC bus, the Allwinner SRAM driver, the
     Apple rtkit firmware driver, Tegra firmware

   - Minor updates for SoC drivers (Samsung, Mediatek, Renesas, Tegra,
     Qualcomm, Broadcom, NXP, ...)

  There are also some separate subsystem with downstream maintainers
  that merge updates this way:

   - Various updates and new drivers in the memory controller subsystem
     for Mediatek and Broadcom SoCs

   - Small set of changes in preparation to add support for FF-A v1.1
     specification later, in the Arm FF-A firmware subsystem

   - debugfs support in the PSCI firmware subsystem"
