I'm very happy to hear that you're working on getting SimpleDRM ready
for merging into the mainline, I actually wanted to discuss this with
you at XDC and/or Plumbers, but I see that you're already on it, which
is great.

As for the whole discussion about adding resource management /
"real hw support" to the simplefb bindings (which I assume SimpleDRM
will support too), I too am fine with doing a new set of bindings for
this under a different compatible string if that is what people want.

Hans
