2022-12-07dt-bindings: media: s5c73m3: Fix reset-gpio descriptorMaíra Canal
The reset-gpios is described as xshutdown-gpios on the required properties, as it is on the driver. Despite that, the device tree example set the property 'reset-gpios' instead of the property 'xshutdown-gpios'. Therefore, this patch updates the example to match the property specified on the driver.

2022-12-07media: dt-bindings: allwinner: h6-vpu-g2: Add IOMMU reference propertyChen-Yu Tsai
The Hantro G2 video decoder block sits behind an IOMMU. The device tree binding needs a property to reference it. Without a reference for the implementation to properly configure the IOMMU, it will fault and cause the video decoder to fail. Add an "iommus" property for referring to the IOMMU port. The master ID in the example is taken from the IOMMU fault error message on Linux, and the number seems to match the order in the user manual's IOMMU diagram.

2022-12-07io_uring: skip spinlocking for ->task_completePavel Begunkov
->task_complete was added to serialised CQE posting by doing it from the task context only (or fallback wq when the task is dead), and now we can use that to avoid taking ->completion_lock while filling CQ entries. The patch skips spinlocking only in two spots, __io_submit_flush_completions() and flushing in io_aux_cqe, it's safer and covers all cases we care about. Extra care is taken to force taking the lock while queueing overflow entries. It fundamentally relies on SINGLE_ISSUER to have only one task posting events. It also need to take into account overflowed CQEs, flushing of which happens in the cq wait path, and so this implementation also needs DEFER_TASKRUN to limit waiters. For the same reason we disable it for SQPOLL, and for IOPOLL as it won't benefit from it in any case. DEFER_TASKRUN, SQPOLL and IOPOLL requirement may be relaxed in the future.

2022-12-07net: dsa: mv88e6xxx: accept phy-mode = "internal" for internal PHY portsVladimir Oltean
The ethernet-controller dt-schema, mostly pushed forward by Linux, has the "internal" PHY mode for denoting MAC connections to an internal PHY. U-Boot may provide device tree blobs where this phy-mode is specified, so make the Linux driver accept them. It appears that the current behavior with phy-mode = "internal" was introduced when mv88e6xxx started reporting supported_interfaces to phylink. Prior to that, I don't think it would have any issues accepting this phy-mode.

2022-12-07bpf: do not rely on ALLOW_ERROR_INJECTION for fmod_retBenjamin Tissoires
The current way of expressing that a non-bpf kernel component is willing to accept that bpf programs can be attached to it and that they can change the return value is to abuse ALLOW_ERROR_INJECTION. This is debated in the link below, and the result is that it is not a reasonable thing to do. Reuse the kfunc declaration structure to also tag the kernel functions we want to be fmodret. This way we can control from any subsystem which functions are being modified by bpf without touching the verifier.

2022-12-07platform/x86/amd: pmc: Add a workaround for an s0i3 issue on CezanneMario Limonciello
Cezanne platforms under the right circumstances have a synchronization problem where attempting to enter s2idle may fail if the x86 cores are put into HLT before hardware resume from the previous attempt has completed. To avoid this issue add a 10-20ms delay before entering s2idle another time. This workaround will only be applied on interrupts that wake the hardware but don't break the s2idle loop.

2022-12-07spi: spi-mtk-nor: Add recovery mechanism for dma read timeoutbayi cheng
The state machine of MTK spi nor controller may be disturbed by some glitch signals from the relevant BUS during dma read, Although the possibility of causing the dma read to fail is next to nothing, However, if error-handling is not implemented, which makes the feature somewhat risky. Add an error-handling mechanism here, reset the state machine and re-read the data when an error occurs.
