Re: cx23885

[Michael <auslands-kv@gmx.de>]

Now comes the best part:

I found a linux driver on the producers web page. And it is written by ... 
Steven Toth :-)

http://www.commell.com.tw/Product/Surveillance/MPX-885/mpx-885.rar

I am looking at the files to see what they have changed (if anything at 
all).

One thing I found pretty fast is that they added in cx23885-card.c:

[CX23885_BOARD_MPX885] = {
	    .name       = "MPX-885",
        .porta      = CX23885_ANALOG_VIDEO,
        .portb      = CX23885_MPEG_ENCODER,
        .portc      = CX23885_MPEG_DVB,
        .input          = {{
            .type   = CX23885_VMUX_COMPOSITE1,
            .vmux   = CX25840_VIN1_CH1,
            .gpio0  = 0,
        }, {
            .type   = CX23885_VMUX_COMPOSITE2,
            .vmux   = CX25840_VIN2_CH1,
            .gpio0  = 0,
        }, {
            .type   = CX23885_VMUX_COMPOSITE3,
            .vmux   = CX25840_VIN3_CH1,
            .gpio0  = 0,
        }, {
            .type   = CX23885_VMUX_COMPOSITE4,
            .vmux   = CX25840_VIN4_CH1,
            .gpio0  = 0,
        } }

Now, concerning the rest of the code, I'm afraid my knowledge is far below 
what is needed to understand just a little bit of it. I can try to compile 
the code, but they state it is for kernel 2.6.21, so I don't know whether it 
compiles for 2.6.31 (or newer).

I can try to make a diff, but I guess there will be lots of changes between 
this rather old code and an actual cx23885 version.

But maybe it is a start. What do you think?
