    android display hal has refined the logic to use block commit when
    there is overlay but without android out fence. This android out
    fence patch can be reverted now.

    Revert "MA-14133 Enable android out fence and normal out fence simultaneously"

    This reverts commit d5d94e0e13b5bdf8b3ab4f60341e00898bbaf3c2.

    Add android out-fence support for DRM, enable android out fence and
    normal out fence simultaneously. Android present fence depends on
    normal out fence which represents current frame on screen. Layer
    release fence depends on android out fence which should be signaled
    when it is off screen.

    Key changes:
    Add DRIVER_ATOMIC_ANDROID_FENCE feature to declare android out-fence support.
    Add ANDROID_OUT_FENCE_PTR property to transfer fence fd.
    Android fence is created when drm_atomic_commit called.
    Add drm_crtc_arm_fence_event to insert fence to queue.
    Add drm_crtc_handle_fence to signal buffer fence off screen.
    Add drm android out-fence to dcss crtc.

    This patch cherry-pick below four patches from L4.19 kernel and do
    some update based on L5.4 kernel changes.

    Add ANDROID_OUT_FENCE_PTR property to transfer fence fd.

    It is not possible to create cross-references for duplicated

    generates warnings like this:

    .../Documentation/gpu/drm-kms-helpers:326: ../drivers/gpu/drm/drm_edid.c:1626: WARNING: Duplicate C declaration, also defined in 'gpu/drm-kms-helpers'.
    Declaration is 'bool drm_edid_are_equal (const struct edid *edid1, const struct edid *edid2)'.

    So, get rid of the duplicated kernel-doc markup.

    - Minor driver fixes and cleanups (octal permissions, error

    - Secure Nested Paging Support for AMD IOMMU. The IOMMU will fault when
    a device tries DMA on memory owned by a guest. This needs new
    fault-types as well as a rewrite of the IOMMU memory semaphore for
    command completions.

    - Allow broken Intel IOMMUs (wrong address widths reported) to still be
    used for interrupt remapping.

    - IOMMU UAPI updates for supporting vSVA, where the IOMMU can access
    address spaces of processes running in a VM.

    - Support for the MT8167 IOMMU in the Mediatek IOMMU driver.

    - Device-tree updates for the Renesas driver to support r8a7742.

    ASoC: Updates for v5.10

    Not a huge amount going on in the core for ASoC this time but quite a
    lot of driver activity, especially for the Intel platforms:

    - Replacement of the DSP driver for some older x86 systems with a new
    one which was written with closer reference to the DSP firmware so
    should hopefully be more robust and maintainable.
    - A big batch of static checker and other fixes for the rest of the x86
    DSP drivers.
    - Cleanup of the error unwinding code from Morimoto-san, hopefully
    making it more robust.
    - Helpers for parsing auxiluary devices from the device tree from
    Stephan Gerhold.
    - New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359
    Microchip S/PDIF TX and RX controllers, Realtek RT1015P, and Texas
    Instruments J721E, TAS2110, TAS2564 and TAS2764

    Current hdac_i915 uses a static completion instance to wait
    for i915 driver to complete the component bind.

    This design is not safe if multiple HDA controllers are active and
    communicating with different i915 instances, and can lead to list
    corruption and failed audio driver probe.

    Fix the design by moving completion mechanism to common acomp
    code and remove the related code from hdac_i915.
