From: Allen-kh Cheng <[e-mail]>

MT8186 is a SoC based on 64bit ARMv8 architecture. It contains 6 CA55 and
2 CA76 cores. MT8186 share many HW IP with MT65xx series. This patchset was 
tested on MT8186 evaluation board to shell.

This series is based on tag: next-20220728, linux-next/master
Since we have a another dts series of mt8195 [1] which is waiting for review from
maintainers. I remove power domains controller node from this series.

There are some corrections in mt8186 hardware bindings. We need to apply the below patches.
