2025-07-24s390/ism: fix concurrency management in ism_cmd()Halil Pasic
The s390x ISM device data sheet clearly states that only one request-response sequence is allowable per ISM function at any point in time. Unfortunately as of today the s390/ism driver in Linux does not honor that requirement. This patch aims to rectify that. This problem was discovered based on Aliaksei's bug report which states that for certain workloads the ISM functions end up entering error state (with PEC 2 as seen from the logs) after a while and as a consequence connections handled by the respective function break, and for future connection requests the ISM device is not considered -- given it is in a dysfunctional state. During further debugging PEC 3A was observed as well. A kernel message like [ 1211.244319] zpci: 061a:00:00.0: Event 0x2 reports an error for PCI function 0x61a is a reliable indicator of the stated function entering error state with PEC 2. Let me also point out that a kernel message like [ 1211.244325] zpci: 061a:00:00.0: The ism driver bound to the device does not support error recovery is a reliable indicator that the ISM function won't be auto-recovered because the ISM driver currently lacks support for it. On a technical level, without this synchronization, commands (inputs to the FW) may be partially or fully overwritten (corrupted) by another CPU trying to issue commands on the same function. There is hard evidence that this can lead to DMB token values being used as DMB IOVAs, leading to PEC 2 PCI events indicating invalid DMA. But this is only one of the failure modes imaginable. In theory even completely losing one command and executing another one twice and then trying to interpret the outputs as if the command we intended to execute was actually executed and not the other one is also possible. Frankly, I don't feel confident about providing an exhaustive list of possible consequences.

2025-07-24gpio: Add new gpio-macsmc driver for Apple MacsHector Martin
This driver implements the GPIO service on top of the SMC framework on Apple Mac machines. In particular, these are the GPIOs present in the PMU IC which are used to control power to certain on-board devices. Although the underlying hardware supports various pin config settings (input/output, open drain, etc.), this driver does not implement that functionality and leaves it up to the firmware to configure things properly. We also don't yet support interrupts/events. This is sufficient for device power control, which is the only thing we need to support at this point. More features will be implemented when needed. To our knowledge, only Apple Silicon Macs implement this SMC feature.

2025-07-24mfd: Add Apple Silicon System Management ControllerSven Peter
The System Management Controller (SMC) on Apple Silicon machines is a piece of hardware that exposes various functionalities such as temperature sensors, voltage/power meters, shutdown/reboot handling, GPIOs and more. Communication happens via a shared mailbox using the RTKit protocol which is also used for other co-processors. The SMC protocol then allows reading and writing many different keys which implement the various features. The MFD core device handles this protocol and exposes it to the sub-devices. Some of the sub-devices are potentially also useful on pre-M1 Apple machines and support for SMCs on these machines can be added at a later time.

2025-07-24i2c: qup: jump out of the loop in case of timeoutYang Xiwen
Original logic only sets the return value but doesn't jump out of the loop if the bus is kept active by a client. This is not expected. A malicious or buggy i2c client can hang the kernel in this case and should be avoided. This is observed during a long time test with a PCA953x GPIO extender. Fix it by changing the logic to not only sets the return value, but also jumps out of the loop and return to the caller with -ETIMEDOUT.

into soc/dt RISC-V Devicetrees for v6.17 Sophgo: For CV18xx serials: There are three major changes. The first is to add the RTCSYS MFD node, which provides rich control registers for soc power management and other rich control functions; the second is to add the reset controller node and add related reset properties for other peripherals; the third is to add ethernet controller related nodes to the soc and enable ethernet device control for HuashanPi. For SG2042: There are three major changes. The first is to add ISA extensions such as xtheadvector/ziccrse/zfh for cpu cores; the second is add ethernet controller support; the third is add two new boards EVB_V1 & EVB_V2 which use SG2042 SoC. For SG2044: There are many changes. The first is to add pmu configuration; the second is to add ISA extensions ziccrse and add missing riscv,cbop-block-size property for cpu cores; the third is to add more peripherals nodes for SoC after clock controller is ready, such as MSI/PCIe/pwm/SPI-NOR etc. This PR also add HWMON MCU device for the sophgo-srd3-10 board and reserve uart0 node for sophgo-srd3-10 board because uart0 is already occupied by the firmware. This PR also moves sophgo.yaml from the riscv directory to soc/sophgo for sharing between riscv and arm. CV18xx SoC contains a RISC-V big core and an ARM64 big core. Moving sophgo.yaml to a shared location will help us add support for ARM cores to the CV18xx chip in the future.

2025-07-23drm/i915/display: Fix dma_fence_wait_timeout() return value handlingAakash Deep Sarkar
dma_fence_wait_timeout returns a long type but the driver is only using the lower 32 bits of the retval and discarding the upper 32 bits. This is particularly problematic if there are already signalled or stub fences on some of the hw planes. In this case the dma_fence_wait_timeout function will immediately return with timeout value MAX_SCHEDULE_TIMEOUT (0x7fffffffffffffff) since the fence is already signalled. If the driver only uses the lower 32 bits of this return value then it'll interpret it as an error code (0xFFFFFFFF or (-1)) and skip the wait on the remaining fences. This issue was first observed in the xe driver with the Android compositor where the GPU composited layer was not properly waited on when there were stub fences in other overlay planes resulting in visual artifacts.

2025-07-23block: fix lbmd_guard_tag_type assignment in FS_IOC_GETLBMD_CAPAnuj Gupta
The blk_get_meta_cap() implementation directly assigns bi->csum_type to the UAPI field lbmd_guard_tag_type. This is not right as the kernel enum blk_integrity_checksum values are not guaranteed to match the UAPI defined values. Fix this by explicitly mapping internal checksum types to UAPI-defined constants to ensure compatibility and correctness, especially for the devices using CRC64 PI.

2025-07-23spi: spi-qpic-snand: simplify bad block marker duplicationGabor Juhos
Due to the expectations of the SPINAND code, the driver duplicates the bad block markers during raw OOB reads. It has been implemented by using two if statements, and due to the opposite conditions one of conditional codepaths always runs. Since the effect of both codepaths is the same, remove the if statements and use a single line solution instead. Also add a note about why the duplication is required. No functional changes intended.
