Current binding document enforces presence of either port@0 (DSI in) or port@1 (DPI IN/OUT), with port@2 (DP out) being optional. This bridge is capable of DSI->DP, DPI->DP and DPI->DP, it is therefore perfectly valid to have both port@0 and port@1 described in the DT, because this is fairy standard DPI->DP configuration of this bridge.

However, this patch modifies the schema to conditionally apply the correct pinctrl schema based on the compatible property. Specifically: - If compatible contains "xlnx,zynqmp-pinctrl", reference xlnx,zynqmp-pinctrl.yaml. - If compatible contains "xlnx,versal-pinctrl", reference xlnx,versal-pinctrl.yaml.

2026-02-03workqueue: add CONFIG_BOOTPARAM_WQ_STALL_PANIC optionBreno Leitao
Add a kernel config option to set the default value of workqueue.panic_on_stall, similar to CONFIG_BOOTPARAM_SOFTLOCKUP_PANIC, CONFIG_BOOTPARAM_HARDLOCKUP_PANIC and CONFIG_BOOTPARAM_HUNG_TASK_PANIC. This allows setting the number of workqueue stalls before triggering a kernel panic at build time, which is useful for high-availability systems that need consistent panic-on-stall, in other words, those servers which run with CONFIG_BOOTPARAM_*_PANIC=y already. The default remains 0 (disabled). Setting it to 1 will panic on the first stall, and higher values will panic after that many stall warnings. The value can still be overridden at runtime via the workqueue.panic_on_stall boot parameter or sysfs. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Tejun Heo <tj@kernel.org>

2026-02-03panic: add panic_force_cpu= parameter to redirect panic to a specific CPUPnina Feder
Some platforms require panic handling to execute on a specific CPU for crash dump to work reliably. This can be due to firmware limitations, interrupt routing constraints, or platform-specific requirements where only a single CPU is able to safely enter the crash kernel. Add the panic_force_cpu= kernel command-line parameter to redirect panic execution to a designated CPU. When the parameter is provided, the CPU that initially triggers panic forwards the panic context to the target CPU via IPI, which then proceeds with the normal panic and kexec flow. The IPI delivery is implemented as a weak function (panic_smp_redirect_cpu) so architectures with NMI support can override it for more reliable delivery. If the specified CPU is invalid, offline, or a panic is already in progress on another CPU, the redirection is skipped and panic continues on the current CPU.

2026-02-03sched/arm64: Move fallback task cpumask to HK_TYPE_DOMAINFrederic Weisbecker
When none of the allowed CPUs of a task are online, it gets migrated to the fallback cpumask which is all the non nohz_full CPUs. However just like nohz_full CPUs, domain isolated CPUs don't want to be disturbed by tasks that have lost their CPU affinities. And since nohz_full rely on domain isolation to work correctly, the housekeeping mask of domain isolated CPUs should always be a subset of the housekeeping mask of nohz_full CPUs (there can be CPUs that are domain isolated but not nohz_full, OTOH there shouldn't be nohz_full CPUs that are not domain isolated): HK_TYPE_DOMAIN & HK_TYPE_KERNEL_NOISE == HK_TYPE_DOMAIN Therefore use HK_TYPE_DOMAIN as the appropriate fallback target for tasks. Note that cpuset isolated partitions are not supported on those systems and may result in undefined behaviour.

Detect spurious retransmission of a previously sent ACK carrying the AccECN option after the second retransmission. Since this might be caused by the middlebox dropping ACK with options it does not recognize, disable the sending of the AccECN option in all subsequent ACKs. This patch follows Section 3.2.3.2.2 of AccECN spec (RFC9768), and a new field (accecn_opt_sent_w_dsack) is added to indicate that an AccECN option was sent with duplicate SACK info. Also, a new AccECN option sending mode is added to tcp_ecn_option sysctl: (TCP_ECN_OPTION_PERSIST), which ignores the AccECN fallback policy and persistently sends AccECN option once it fits into TCP option space.

2026-02-02dt-bindings: net: renesas,rzv2h-gbeth: Document Renesas RZ/G3L SoCBiju Das
Add device tree binding support for the Gigabit Ethernet (GBETH) IP on Renesas RZ/G3L SoC. This SoC uses different Synopsys DesignWare MAC version 5.30 compared to RZ/G3E. RZ/G3L requires an extra clock compared to RZ/G3E and has pps interrupts. Add a new compatible string "renesas,r9a08g046-gbeth" for RZ/G3L SoC and update the schema to handle hardware differences between SoC variants. Extend the base snps,dwmac.yaml schema to accommodate the PPS interrupts.

2026-02-03erofs: separate plain and compressed filesystems formallyGao Xiang
The EROFS on-disk format uses a tiny, plain metadata design that prioritizes performance and minimizes complex inconsistencies against common writable disk filesystems (almost all serious metadata inconsistency cannot happen in well-designed immutable filesystems like EROFS). EROFS deliberately avoids artificial design flaws to eliminate serious security risks from untrusted remote sources by design, although human-made implementation bugs can still happen sometimes. Currently, there is no strict check to prevent compressed inodes, especially LZ4-compressed inodes, from being read in plain filesystems. Starting with erofs-utils 1.0 and Linux 5.3, LZ4_0PADDING sb feature is automatically enabled for LZ4-compressed EROFS images to support in-place decompression. Furthermore, since Linux 5.4 LTS is no longer supported, we no longer need to handle ancient LZ4-compressed EROFS images generated by erofs-utils prior to 1.0. To formally distinguish different filesystem types for improved security: - Use the presence of LZ4_0PADDING or a non-zero `dsb->u1.lz4_max_distance` as a marker for compressed filesystems containing LZ4-compressed inodes only; - For other algorithms, use `dsb->u1.available_compr_algs` bitmap. Note: LZ4_0PADDING has been supported since Linux 5.4 (the first formal kernel version), so exposing it via sysfs is no longer necessary and is now deprecated (but remain it for five more years until 2031): `dsb->u1` has been strictly non-zero for all EROFS images containing compressed inodes starting with erofs-utils v1.3 and it is actually a much better marker for compressed filesystems.

2026-02-02Anbernic RG-DS AW87391 Speaker AmpsMark Brown
Merge series from Chris Morgan <macroalpha82@gmail.com>: Add support for the Anbernic RG-DS Speaker Amplifiers. The Anbernic RG-DS uses two AW87391 ICs at 0x58 and 0x5B on i2c2. However, the manufacturer did not provide a firmware file, only a sequence of register writes to each device to enable and disable them. Add support for this *specific* configuration in the AW87390 driver. Since we are relying on a device specific sequence I am using a device specific compatible string. This driver does not currently support the aw87391 for any other device as I have none to test with valid firmware. Attempts to create firmware with the AwinicSCPv4 have not been successful.
