Personally, I would split that addition in a different commit, explaining what mmsys, camsys and apu clocks are ;-) Regards, Angelo

This commits are based on the Fabien Parent <fparent@baylibre.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 two others which add power support for MT8365 SoC [1] [2].
