804258c95f V4L/DVB: dvb: add lgdt3304 support to lgdt3305 driver
There's a currently-unused lgdt3304 demod driver, which leaves a lot to
be desired as far as functionality. The 3304 is unsurprisingly quite
similar to the 3305, and empirical testing yeilds far better results
and more complete functionality by merging 3304 support into the 3305
driver. (For example, the current lgdt3304 driver lacks support for
signal strength, snr, ucblocks, etc., which we get w/the lgdt3305).

For the moment, not dropping the lgdt3304 driver, and its still up to
a given device's config setup to choose which demod driver to use, but
I'd suggest dropping the 3304 driver entirely.

As a follow-up to this patch, I've got another patch that adds support
for the KWorld PlusTV 340U (ATSC) em2870-based tuner stick, driving
its lgdt3304 demod via this lgdt3305 driver, which is what I used to
successfully test this patch with both VSB_8 and QAM_256 signals.

A few pieces are still a touch crude, but I think its a solid start,
as well as much cleaner and more feature-complete than the existing
lgdt3304 driver.

There is a problem with certain tv8532 cams, where sometimes there
hsync/vsync locks one pixel of where it normally locks. While trying to
fix this (which I failed to do). I noticed there are lots if duplicate

patch cleanes these ups (which has no negative effects, but unfortunately
also does not help).

With the ovfx2 bridge sometimes the first few frames in a stream
would be no good, as the bridge and sensor are not in complete hsync /
vsync yet. This can easily be detected by checking the framesize. So if the
framesize is short and it is one of the 1ste 3 frames after an sd_start,
drop it.

66e89522af V4L/DVB: IR: add mceusb IR receiver driver
This is a new driver for the Windows Media Center Edition/eHome
Infrared Remote transceiver devices. Its a port of the current
lirc_mceusb driver to ir-core, and currently lacks transmit support,
but will grow it back soon enough... This driver also differs from
lirc_mceusb in that it borrows heavily from a simplified IR buffer
decode routine found in Jon Smirl's earlier ir-mceusb port.

This driver has been tested on the original first-generation MCE IR
device with the MS vendor ID, as well as a current-generation device
with a Topseed vendor ID. Every receiver supported by lirc_mceusb
should work equally well. Testing was done primarily with RC6 MCE
remotes, but also briefly with a Hauppauge RC5 remote, and all works
as expected.

v2: fix call to ir_raw_event_handle so repeats work as they should.

in later...

easier for receivers that support all IR protocols.

Rather than registering all IR protocol decoders as enabled when bringing
up a new device, only enable the IR protocol decoder that matches the
keymap being loaded. Additional decoders can be enabled on the fly by
those that need to, either by twiddling sysfs bits or by using the
ir-keytable util from v4l-utils.

Functional testing done with the mceusb driver, and it behaves as expected,
only the rc6 decoder is enabled, keys are all handled properly, etc.

Self-NAK. The only place we actually *care* about the retval from a
RUN_DECODER() call is in __ir_input_register(), and currently, its
looking for retval < 0, which is currently never possible. When we're
running the decoders, either they fail and return -EINVAL or they
succeed and return 0, and in the register case, we get either a
negative error (ex: -ENOMEM from rc6) or 0, so with the above, _sumrc
will *always* be 0 in the two cases I'm looking at. The third place
where RUN_DECODER gets called (decoder unregister) doesn't care about
the retval either. New patch below, including updated comments about
the macro.
