Subject: [GIT PULL] iommu/arm-smmu: Updates for 6.9

Hi Joerg,

Please pull these Arm SMMU updates for 6.9. There's the usual crop of
device-tree changes, but the meat of the work is part one of the SMMUv3
IOMMUFD-enabling work from Jason.

The branch is based on the fixes tag I sent you before and there's the
usual brief summary in the tag.

Cheers,

Will

  iommu/arm-smmu-v3: Convert to domain_alloc_paging() (2024-02-29 15:12:23 +0000)

----------------------------------------------------------------
Arm SMMU updates for 6.9

- Device-tree binding updates for a bunch of Qualcomm SoCs

- SMMUv2:
  * Support for Qualcomm X1E80100 MDSS

- SMMUv3:
  * Significant rework of the driver's STE manipulation and domain
    handling code. This is the initial part of a larger scale rework
    aiming to improve the driver's implementation of the IOMMU API
    in preparation for hooking up IOMMUFD support.

----------------------------------------------------------------
Abel Vesa (1):
      iommu/arm-smmu-qcom: Add X1E80100 MDSS compatible
