I have some other work pending which relies on this too since I don't
want to get stuck I want to get forward asap.
The reason why I redid it back than was I tried to find a better
solution and in case of that I'm fine with that solution now since it
works flawlessly with the saa7134 and cx88 too.
The last discussion before this one was to get the patches ready for
merging with the upstream code, I exported it again and now again it's
having a hard time. I just one more time spent another full day with
doing and testing all that.
This is not acceptable for me anymore, and I'm very sure that this
time wasting mentality will go on with other projects too which join
the current linuxtv project.
I seriously discussed this way in private with some developers,
surprisingly some of them had nearly the same idea as I wrote already.
There are many ways devices can be built, there will never be one way
which will cover all board designs, Manu listed some possibilities,
maybe he should also have written what about devices which do not have
a tuner either and are directly fed with input data. My current work
is based on what is available now on the market.
All the tuners which are written as dvb tuner modules at the moment
are i2c tuners, using dvb_attach it's still possible to override the
structs with completly different callbacks.
I will not go back anymore, instead a fork off seems to be a good
solution if the linuxtv project wants to stay stuck where it is at the
moment it should do so.
I'm very sure almost noone even had a look at the code. Since around 1
1/2 years there hasn't been any solution, linuxtv can go for another
10 years I don't mind but then without em28xx(analogue/digital)
support which is very popular at the moment, and also lacking support
for the xc3028 hybrid devices.
