Subject: [PATCH v7 0/4] Add IOMMU driver for rk356x

This series adds the IOMMU driver for rk356x SoC.
Since a new compatible is needed to distinguish this second version of 
IOMMU hardware block from the first one, it is an opportunity to convert
the binding to DT schema.

version 7:
 - Set DMA mask
 - Fix rk_iommu_enable()
 - rebased on v5.13-rc3 tag

version 6:
 - Remove #include <module.h>
 - Remove pt_address_mask field
 - Only use once of_device_get_match_data
 - Return an error if ops don't match

version 5:
 - Add internal ops inside the driver to be able to add variants.
 - Add support of v2 variant.
 - Stop using 'version' field
 - Use GENMASK macro

version 4:
 - Add description for reg items
 - Remove useless interrupt-names properties
 - Add description for interrupts items
 - Remove interrupt-names properties from DST files

version 3:
 - Rename compatible with soc prefix
 - Rebase on v5.12 tag

version 2:
 - Fix iommu-cells typo in rk322x.dtsi
 - Change maintainer
 - Change reg maxItems
 - Add power-domains property
 
Benjamin Gaignard (4):
  dt-bindings: iommu: rockchip: Convert IOMMU to DT schema
  dt-bindings: iommu: rockchip: Add compatible for v2
  iommu: rockchip: Add internal ops to handle variants
  iommu: rockchip: Add support for iommu v2
