Moikka!
RegMap does not belong to media (v4l) but driver core. Maybe kernel 3.8
is too old and does not have that functionality.
no, it is in kernel core itself (not as module).
Update your kernel. Why you don't use it9135 driver shipped with 3.8
kernel?
while did not tune (tzap do not lock and shows snr=00000 and lines on
output comes out very slow and irregularly). It is not normal.
There is no reason on my side, why it should not work:
I had use yet 3 months ago with 3.2.0 kernel with compiled V4L new
AF9035 module, but unfortunately now (in 9/2014 ?) this driver has
changed and requires now kernel >=3.4.
And I did not find out, how to get older git tree from +- 8/2014 to use
it with my 3.2 kernel. That's why I have install newer 3.8 kernel.

-> don't know, how to get regmap-i2c module.
It is a part of V4L ?

---------------------
What is wrong ?
it913x_probe() fails with error -EINVAL. There is only 2 ways it could
fail, kzalloc() and regmap_init_i2c(). It must be later one.
Do you have regmap module installed?
What says: "modinfo regmap-i2c" command?
