Linus Torvalds d076a8d3b9 IOMMU Updates for Linux v7.2
Including:
 
 Core Code:
 
   - Fix dma-iommu scatterlist length handling in the P2PDMA path.
 
   - Extend the generic IOMMU page-table code with detailed gather
     support for more precise invalidations.
 
   - Add pending-gather tracking to generic page-table invalidation
     handling.
 
   - Add support for smaller virtual address sizes in the generic AMDv1
     page-table format, including KUnit coverage.
 
   - Fix page-size bitmap calculation for smaller VA configurations.
 
   - Rework Arm io-pgtable allocation/freeing to consistently use the
     iommu-pages API and address-conversion helpers.

     always-on ATS handling for pre-CXL devices.
 
 AMD IOMMU:
 
   - Fix several IOTLB invalidation details, including PDE handling,
     flush-all behavior, and command address encoding.
 
   - Honor IVINFO[VASIZE] when deriving address limits.
 
   - Fix premature loop termination in init_iommu_one().
 
   - Add Hygon family 18h model 4h IOAPIC support.

   - SMMUv2:
     - Device-tree binding updates for Qualcomm Hawi, Nord and Shikra
       SoCs.
     - Constain the clocks which can be specified for recent Qualcomm
       SoCs.

       configuration an add new entry for the Glymur MDSS.
     - Ensure SMMU is powered-up when writing context bank for Adreno
       client.
 
   - SMMUv3:
     - Fix off-by-one in queue allocation retry loop.
     - Enable hardware update of access/dirty bits from the SMMU.
     - Re-jig command construction to use separate inline helpers for
       each command type.
 
 Intel VT-d:
 
   - Add the PCI segment number to DMA fault messages.
 
   - Improve support for non-PRI mode SVA.
 
   - Ensure atomicity during context entry teardown.
 
   - Fix RB-tree corruption in the probe error path.
 
 RISC-V IOMMU:
 
   - Add NAPOT range invalidation support.
 
   - Use detailed gather information for invalidation decisions.
 
   - Compute the best stride for single invalidations.
 
   - Advertise Svpbmt support to the generic page-table code.
 
   - Add capability definitions and clean up command macro encoding.
 
 VeriSilicon IOMMU:
 
   - Add a new VeriSilicon IOMMU driver.
 
   - Add devicetree binding documentation and MAINTAINERS coverage.
 
   - Add the RK3588 VeriSilicon IOMMU node.
 
   - Apply small cleanups and warning fixes in the new driver.
 
 Rockchip IOMMU:
 
   - Disable the fetch DTE time limit.
 
 Apple DART:
 
   - Correct a stale CONFIG_PCIE_APPLE macro name in a comment.
