Subject: [GIT PULL] iommu/arm-smmu: Updates for 6.6

Hi Joerg,

Please pull these Arm SMMU updates for 6.6. It's almost exclusively
Qualcomm-related SMMUv2 changes but there are some SMMUv3 changes in the
pipeline for next time.

Summary in the tag.

Cheers,

Will

Qualc^WArm SMMU updates for 6.6

- Device-tree binding updates:
  * Add additional compatible strings for Qualcomm SoCs
  * Allow ASIDs to be configured in the DT to work around Qualcomm's
    broken hypervisor
  * Fix clocks for Qualcomm's MSM8998 SoC

- SMMUv2:
  * Support for Qualcomm's legacy firmware implementation featured on
    at least MSM8956 and MSM8976.
  * Match compatible strings for Qualcomm SM6350 and SM6375 SoC variants

- SMMUv3:
  * Use 'ida' instead of a bitmap for VMID allocation
