I will modify it in next version.

Place all the MMIO peripherals under one or more simple-bus nodes.

Do you mean need to add simple-bus like this?
Yes.
We remove soc because Matthias suggested it in former MTK SoC maybe in
2015 year.

We will add it back by your comment.

Thank you.

Erin
Hi, Matthias,
Do you have any comment here?
Although I wasn't able to find it in the documentation my understanding is, that
all devices on-chip should be under soc "bus".

I'm sorry if I created confusion with comments in the past.

Regards,
Matthias
OK! we will add soc "bus" back in next version.
Thank you for your comment.
