Oh, that is wrong. It is registers addresses, Never touch this.
Let's look on that part of code:
/* GPIO's for LNB power control */
#define DM1105_LNB_MASK 0x00000000 // later in
code write it to
DM1105_GPIOCTR, all GPIO's as OUT
#define DM1105_LNB_OFF 0x00020000 // later in
code write it to
DM1105_GPIOVAL, set GPIO17 to HIGH
But you have not to change this.
Right way is to write another entry in cards structure and so on.
Better leave it to me.

Thanks for all your help, I understand better now. I have moved to
code
like that at the bottom. It still doesn't work, but feels a lot
closer.
Before I keep playing with values, I want to check I'm on the right
track.
Does it look right? Specific questions:
1. I see there is a hw_init function. Should I be using that? I
put the
logic into fe_attach because there was already card-specific logic in
there. But this feels like hw initialisation.
2. Should I set the control to input or output? I'm assuming input
= 1.
3. Would pin 15 be numbered from the left or right - is it 0x4, or
0x2000?
Thanks,
Paul
