Hi Angus, There are still lots of SAI patches that need to be upstream.

Aren't > the registers at a different offset from "fsl,imx6sx-sai". Yes, you are right on this. We are trying to slowly push all our internal-tree patches to mainline. Obviously, with started with low hanging fruits, DTS nodes and small SAI fixes. Soon, we will start to send patches for SAI IP ipgrade for imx8. > > How is this supposed to work ? > For the moment it won't work unless we will upstream all our SAI internal patches. But we will get there hopefully this summer.
