[PATCH v6 0/4] Add IOMMU driver for rk356x

From: Benjamin Gaignard
Date: Fri May 21 2021 - 09:40:40 EST


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 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
