OK! I have a new series of patches almost ready. I'll be sending it
tomorrow, after addressing your concerns.

Ok, I'll fix it.

cx25840 is not (always) an I2C. On most devices, this is actually an IP
block inside the bridge chipset.
That's why I didn't include it on patch 1/1. There's one thing to
notice about that, though: while most of the header is describing
the driver interface, it does contain one platform_data in the end:
/* pvr150_workaround activates a workaround for a hardware bug that is
present in Hauppauge PVR-150 (and possibly PVR-500) cards that have
certain NTSC tuners (tveeprom tuner model numbers 85, 99 and 112). The
audio autodetect fails on some channels for these models and the workaround
is to select the audio standard explicitly. Many thanks to Hauppauge for
providing this information.
This platform data only needs to be supplied by the ivtv driver. */
struct cx25840_platform_data {
int pvr150_workaround;
};
While we might split it, I guess it is not worth, specially since
I don't think we'll see any new driver using it.
Also, this is actually a hack used only by the ivtv driver.

Mauro
