Re: [PATCH 0/5] Digital Devices PCIe bridge update to 0.9.15a

That patchset is simply far away from merge. Tons of issues to be fixed. 
It is huge amount of work to get that all in. I could estimate one month 
full time work even my experience is not enough. And I simply don't want 
to waste that much money from my pockets, it is many thousand euros. So 
I do it, if I do, on my schedule.

There is many separate issues which needs to be done. It is not 
something one people should do all. For example mainlining that 
DVB-T/T2/C/C2 demod driver. Another thing is DVB-C2 API, which is not 
much coding, but a lot of specification. You need to read and 
*understand* DVB-C2 spec and on some level other specs (mostly DVB-T2) 
in order to add missing pieces correctly to DVB API. If you are not 
coder, start here.
