2026-03-25media: staging: imx: configure src_mux in csi_startMichael Tretter
After media_pipeline_start() was called, the media graph is assumed to be validated. It won't be validated again if a second stream starts. The imx-media-csi driver, however, changes hardware configuration in the link_validate() callback. This can result in started streams with misconfigured hardware. In the concrete example, the ipu2_csi1 is driven by a parallel video input. After the media pipeline has been started with this configuration, a second stream is configured to use ipu1_csi0 with MIPI-CSI input from imx6-mipi-csi2. This may require the reconfiguration of ipu1_csi0 with ipu_set_csi_src_mux(). Since the media pipeline is already running, link_validate won't be called, and the ipu1_csi0 won't be reconfigured. The resulting video is broken, because the ipu1_csi0 is misconfigured, but no error is reported. Move ipu_set_csi_src_mux from csi_link_validate to csi_start to ensure that input to ipu1_csi0 is configured correctly when starting the stream. This is a local reconfiguration in ipu1_csi0 and is possible while the media pipeline is running. Since csi_start() is called with priv->lock already locked, csi_set_src() must not lock priv->lock again. Thus, the mutex_lock() is dropped.

2026-03-25PCI: hv: Set default NUMA node to 0 for devices without affinity infoLong Li
When hv_pci_assign_numa_node() processes a device that does not have HV_PCI_DEVICE_FLAG_NUMA_AFFINITY set or has an out-of-range virtual_numa_node, the device NUMA node is left unset. On x86_64, the uninitialized default happens to be 0, but on ARM64 it is NUMA_NO_NODE (-1). Tests show that when no NUMA information is available from the Hyper-V host, devices perform best when assigned to node 0. With NUMA_NO_NODE the kernel may spread work across NUMA nodes, which degrades performance on Hyper-V, particularly for high-throughput devices like MANA. Always set the device NUMA node to 0 before the conditional NUMA affinity check, so that devices get a performant default when the host provides no NUMA information, and behavior is consistent on both x86_64 and ARM64.

2026-03-25clk: renesas: r9a06g032: Enable watchdog reset sourcesHerve Codina (Schneider Electric)
The watchdog timeout is signaled using an interrupt and, on this interrupt, a software initiated reset is performed. This software initiated reset performs, in the end, a hardware system reset using SWRST_REQ of RSTCTRL register. The watchdog itself is able to control directly the hardware system reset without any operation done by the interrupt handler. This feature allows the watchdog to not depend on the software to reset the system when a watchdog timeout occurs. Indeed, when the watchdog timeout occurs, the watchdog requests a system reset using its own hardware dedicated line but this reset source is disabled at the reset controller level. To benefit of this feature and be robust against software issues, enable watchdogs reset sources.

2026-03-25mtd: rawnand: sunxi: change error prone variable nameRichard Genoud
In sunxi_nand_hw_ecc_ctrl_init(), i is used as a loop index variable and at the same time as the value used to set ECC mode in ECC control register. To prevent it from being re-used as a loop variable, let's change the naming to ecc_mode. No functional change.
