Subject: [PATCH v3 0/7] Add IOMMU support to MT8365 SoC

This commits are based on the Fabien Parent <fparent@...libre.com> work.

The purpose of this series is to add the following HWs / IPs support for
the MT8365 SoC:
- System Power Manager
- MultiMedia Memory Management Unit "M4U" (IOMMU)
  - Smart Multimedia Interface "SMI"
    - Local arbiter "LARB"

This series depends to 3 others which:
- improve mt8365 support [1]
- add power support for MT8365 SoC [2]
- add smi driver support and bindings for MT8365 SoC [3]

Regards,
Alex

Changes in v3:
- SMI driver support and bindings patches have been removed from
  this series and sent it in another one which should be merged before
  this one.
  - "dt-bindings: memory-controllers: mediatek,smi-larb: add mt8365"
  - "dt-bindings: memory-controllers: mediatek,smi-common: add mt8365"
  - "memory: mtk-smi: mt8365: Add SMI Support"
- Link to v2: https://lore.kernel.org/r/20230207-iommu-support-v2-0-60d5fa00e4e5@baylibre.com

Changes in v2:
- Split power domain patch (3) in 4 patches to explain in the commit
  messages the added subsystems.
- Add an independent "mediatek,mt8365-smi-common" compatible to have
  its own LARB bus select.
- Link to v1: https://lore.kernel.org/r/20230207-iommu-support-v1-0-4f0c81fd52c1@baylibre.com
