Hi Joerg,

Please pull these Arm SMMU updates for 6.7. Usual summary in the tag,
but the bulk of this is refactoring to the way in which the SMMUv3
driver handles context descriptors in preparation for implementing the
'->set_dev_pasid()' operation for non-SVA domains. And of course there's
the obligatory DT updates for Qualcomm platforms.

Cheers,

Will
