Mauro,

Please disregard my previous pull request and instead please pull from:

http://linuxtv.org/hg/~awalls/v4l-dvb

for:

cx18: Add interlock so sliced VBI insertion only happens for an MPEG PS
cx18: Fix VPS service register codes
cx18: Correct comments about vertical and horizontal blanking timings
cx18: Fix s-parse warnings and a logic error about extracting the VBI PTS
cx18: Include cx18-audio.h in cx18-audio.c to eliminate s-parse warning
cx18: Fix a video scaling check problem introduced by sliced VBI changes
cx18: Use strlcpy() instead of strncpy() for temp eeprom i2c_client setup

This collections of changesets do not have the "#include <linux/ivtv.h>"
that was in my previous pull request.

Regards,
Andy

The TCL MNM05-4 appears to have a TDA9887 based on tuner chip
autodetection:

http://ivtvdriver.org/pipermail/ivtv-users/2009-May/009388.html

and it supports M systems since it is on an HVR-1600 sold in an NTSC-M
market.

The EEPROM on the particular HVR-1600 says no radio is supported. Maybe
the tuner actually does support FM radio, but it just isn't wired up on
the HVR-1600. Maybe FM AF baseband doesn't come out of the tuner, but
SIF can still be used to demodulate FM radio. I don't know.

When looking through the list in tuner-types.c only 2 analog-only, NTSC
tuners had a TDA9887:

TUNER_PANASONIC_VP27 type 46
TUNER_PHILIPS_FM1236_MK3 type 43

Since the TCL MFNM05-4, which has FM radio, was using the
TUNER_PHILIPS_FM1236_MK3 type, I guessed the MNM05-04 would be very
close.

Can the tda9887 detection code in Linux give a false positive?

Regards,
Andy
