Hi Tino! Hi List!

as you know I already did some work regarding zl10036 and mt312/zl10313.
I did manage to let the whole thing run. Just it got back to crashing my 
machine so I cannot provide a patch-series yet.

So I need to check where my memory-access bug lies. Then I can provide a 
working zl10036 driver (largely rewritten from your version). But still 
bandwidth handling is not good - just good enough to get a lock :)

Second I have a patch-series to change mt312 driver to support zl10313 as 
zl10313 is almost identical mt312 (from driver perspective).

Maybe this will be done in 1 or 2 weeks (I hope so).

Regards
Matthias
