Subject: Re: [PATCH 3/3] imx8mq.dtsi: add the sdma nodes

Hi Angus,

What is the status of this patch? Most likely this should go through
Shwan's tree.

I noticed that I have also sent a similar patch to Shawn:
https://www.spinics.net/lists/arm-kernel/msg708424.html

So, lets coordinate and work better on this.

I am now preparing another series where I add SAI nodes and enable WM
codec on imx8MQ.

If you don't mind I will pick your relevant changes from this patch
and add them to my series, then send them to Shawn.

thanks,
Daniel.
