| drivers/media/dvb/frontends/cx24116.c:573: warning: passing argument 3 of 'cx24116_writeregN' discards qualifiers from pointer target type
Make the `data' input pointer parameter of cx24116_writeregN() const to
kill the warning.

From: Christophe Thommeret <hftom@free.fr>
Christophe divulged the following:
"Since 8PSK (and higher mod) signals are very likely to have pilot symbols,
pilot_auto should start with pilot_on for 8PSK.
And since QPSK signals are unlikely to have pilot, pilot_auto should start
with pilot_off for QPSK.
Without the patch:
QPSK tuning delay: ~100ms
8PSK tuning delay: ~900ms
with patch:
QPSK tuning delay: ~100ms
8PSK tuning delay: ~100ms
"
This patch does as Cristophe asks. In emulated auto-pilot we
choose pilot-on for tuning PSK_8 and pilot-off for
tuning QPSK.

I've retained the older percentage code after discussing this with
Darron Broad, but made the ESNO option default.

... and cleanup any drivers using them.
I've also removed NBC_QPSK and modified the cx24116 driver to check
the delivery_type also, removing some excess namespace baggage.

From: Darron Broad <darron@kewl.org>
Add some sanity checking to data input via S2API to the cx24116 demod.
This patch is valid for both s2-mfe and s2.
It was found when testing KAFFEINE with S2API support that invalid
modulation modes amongst other parameters were being delivered to
the demod. In order to debug this sanity checking has been added.
An example session would involve kaffeine setting QAM_AUTO when
querying DVB-T, then later when trying to tune to DVB-S this
cached value would be presented in error.

From the author:
Here is a simple patch detailing some reverse engineered
register detail lost in my latest merge. The comments
in the code refer to this register but it is never
defined. This corrects this.

Adjust MPEG initialization in cx24116 in order to accomodate different
MPEG CLK position and polarity in different cards. For example, HVR4000
uses 0x02 value, but DvbWorld & TeVii USB cards uses 0x01. Without it MPEG
stream was broken on that cards for symbol rates > 30000 kSyms/s.

Remove the debugging sysctls.
Rolloff was broken, not it works as expected and has been tested in kaffeine.
Power related changes for the isl6421 are not implemented on the HVR4000/4000LITE.

I was given these changes by Darron Broad and Igor Liplianin and represent a series
of patches they've been making to the cx24116 driver over the last two years.
Changes for handling symbolrates >30Ksps
Tone handling changes.
Diseqc support.
Sleep support, shutting down the clocks correctly.
Cleanup on ROLL_OFF and PILOT support.
*** ST - We need to cleanup the sysclt control, this is abnormal
in a demod driver. We should work towards understanding the missing
API's and ensure we have them in S2API. ***

The frontends will be notified (if they chose) of all _get and _set commands
so they can help determine result or action. Results are now returned
to userspace correctly.

After discussion the following changes were made:
1. Removed the typedefs in frontend.h, use structures.
2. In the frontend.h, remove the 16 command limit on the API and
switch to a flexible variable length API. For practical reasons
a #define limits this to 64, this should be discussed.
3. Changed dvb-core ioctl handing to deal with variable sequences
of commands.
tune-v0.0.3.c is required to use this API, it contains the interface changes.
