I thought '186' and '194' got interchanged in your previous comment because it is 194+title: NVIDIA Tegra GPC DMA Controller Device Tree Bindings

Still not how 'compatible' works nor what I wrote out for you.
which is the superset of 186 and have got more features than 186.
Or probably I did not understand the idea correctly yet.
Hi Rob, this is the way around that we want it. Tegra194 is backward compatible with Tegra186. The above does align with what you mentioned before, so I am also not clear what the issue is with the above?
