It is not my driver ;) And at the beginning it looks quite scary but
it may help together with the dump. You can find it

I accept the challenge :p but where is your fc2580 driver? And in that
thought, where is antti's stub driver :)
That might help me get started :)

Hi Oliver,
the Realtek driver sources I have also contain a fc2580 driver. Maybe
the source code will help you together with the usb sniff.

Would love to, even tried a bit, but don't really know how to start,
what
to use as a template. I think I can extract the i2c messages from the
dreaded ugly af903 driver however, using src or usbsniff.

I have some old stubbed drivers that just works for one frequency

FC2580? Do you have anything for/from that driver? My USB stick as an
AFA9035 based one, using that specific tuner.
Nothing but stubbed driver that contains static register values taken
from
the sniff and it just tunes to one channel (IIRC 634 MHz / 8 MHz BW).
Feel free to contribute new tuner driver in order to add support for
your
AF9035 device.
Here are my sniffs and stubbed driver etc. what I found from the HD.
Those well commented sniffs, both RTL2831U and RTL2832U, are surely most
valuable material.

FC2580 can be found from both AF9035 and RTL2832U codes.
Generally, as coding new demod driver for example, you want to use that
kind of stubbed tuner "driver" for example:
/* FC0011: 634 MHz / BW 8 MHz */
struct {
u8 r[8];
int len;
} regs[] = {
{{ 0x07, 0x0f }, 2 },
{{ 0x08, 0x3e }, 2 },
{{ 0x0a, 0xb8 }, 2 },
{{ 0x0b, 0x80 }, 2 },
{{ 0x0d, 0x04 }, 2 },
{{ 0x00, 0x00, 0x05, 0x11, 0xf1, 0xc7, 0x0a, 0x30 }, 8 },
{{ 0x0e, 0x80 }, 2 },
{{ 0x0e, 0x00 }, 2 },
{{ 0x0e, 0x00 }, 2 },
{{ 0x0e }, 1 },
{{ 0x06, 0x30 }, 2 },
{{ 0x0d }, 1 },
{{ 0x0d, 0x14 }, 2 },
{{ 0x10, 0x0b }, 2 },
};
for (i = 0; i < ARRAY_SIZE(regs); i++) {
pr_debug("%s: i=%d len=%d data=%02x\n", __func__, i, regs[i].len,
regs[i].r[0]);
struct i2c_msg msg[1] = {
{
.addr = 0x60,
.flags = 0,
.len = regs[i].len,
.buf = regs[i].r,
}
};
ret = i2c_transfer(state->i2c, msg, 1);
if (ret != 1)
pr_debug("%s: I2C write failed i=%d len=%d data=%02x\n", __func__, i,
regs[i].len, regs[i].r[0]);
}
