[PATCH RESEND v4 00/18] arm64: dts: imx8: architecture improvement and adding imx8qm support

[Aisheng Dong]

Hi Shawn,

Could you please help take a look at this patch series? It's been without comments for months.
Please let me know if you want me to resend now or I can resend later with new comments addressed if any.

> v4-resend:
>  * no change except put three module binding patches first which are used
>    by this patchset.
> v3->v4:
>  * mainly rebase to latest kernel except a few very minor changes like change
> to use
>    new scu protocol binding which was not supported in last version
> v2->v3:
>  * use clock-indices property instead of bit-offset property suggested by
> Shawn Guo
>  * rebase to latest shawn/for-next
> v1->v2:
>  * change to the new two cells scu clock binding, so original adding scu clocks
>    patches were removed.
>  * Move scu pd node above clk node
