Re: Re: Re: Mystique SaTiX-S2 Sky Xpress DUAL card

Hello, do you exactly read the codes?
Both of you refer to the codes from Montage Technology. That is why the identical in ds3000 code.
in m88ds3103.c, it support the new demodulator m88ds3103 and new tuner ts2022, also backward to support ds3000 and ts2020.
The firmware for ds3103 is not compatible with ds3000. and the tuning control is also different too.
So does tuner ts2022.

It design the new initilase logic. 
In your ds3000.c file, it will download firmware every time when the application tunes the transponders.
Downloading firmware needs lock the firmware file and do many i2c transactions. It will slow down the channel tuning.
It is unnecessary. You maybe refer to conexant cx24116 code to do that.
But it is different between Montage chips and cx24116 chip. It is the right thing in cx24116, it is not for Montage chips.
In m88ds3103.c, it is only one time to download the firmware not every time.

It also fix the bug in reading back tuner register.
In your ds3000.c file, it is wrong to do read tuner register. So it is wrong value when reading back.

It support demod/tuner wake and sleep function.
When the application close or not use dvb device, in m88ds3103.c it will put the demod/tuner in the sleep to save power.
In ds3000.c, it is null.
I do not want to list all let this mail become a long one.

I do not want to argue with you.
So what is the right thing let "Bestunar" do?
They create the hardware. The end user like it and want to use it in Linux.
Linux is open sourced and GPL. So every one can do change in any source code. 
"Bestunar" really change the code and open to the public. 
But they should put your copyright and name in their m88ds3103.c, is it right?
For ds3000.c file, need your permission. If you deny, that they can not change it. is it right?
If you agree, whatever they do. They can not put their copyright and name. is it right?

hello, and what's exactly the different in 'm88ds3103.c' then your
approach before - you just do the same and now even remove my name
from the copyright, which is really ridiculous because almost all of
your code is copy&paste from my code inside 'ds3000.c'. so, in
'm88ds3103.c' you take 'ds3000.c' code, make some small patches to add
ds3103 support, which are mainly one array of initialization values
and even this time remove my name from the copyright, while 90% of the
code inside 'm88ds3103.c'  is made by me - you even leave my comments
from the 'ds3000.c' code letter by letter. so, if you want to claim
copyright, please develop your own code that doesn't use like 90% (and
even more) of mine code.
