This commits are based on the Fabien Parent <[email protected]> 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 serie depends to another one which add power support for MT8365
SoC [1].
Regards,
Alex

Local arbiter (LARB) is a component of Smart Multimedia Interface (SMI),
used to help the memory management (IOMMU).
This patch add 4 LARBs and 2 clocks for the larb1 and larb3 support.

2.25.1
Camera System (CamSys) incorporates an enhanced feature based image
signal processor to connect a variety of image sensor components. This
processor consists of timing generated unit (TG), lens/sensor
compensation unit and image process unit.
For more detail, ask Mediatek for the MT8365 IoT application processor
functional specification.
