ebb8d68a5c V4L/DVB (9048): add a general-purpose callback pointer to struct dvb_frontend
Remove tuner_callback pointers from tuner driver configuration
and private state structures, replaced with a general-purpose
callback pointer within struct dvb_frontend.

A new parameter is added to the callback function, called
component. This allows us to use this callback pointer by
frontend components other than the tuner, if need be. So
far, this is only used by tuner drivers.

bdc203e156 V4L/DVB (9039): Add support for new i2c API provided in firmware version 1.20
The Pinnacle PCTV HD Pro has an xc5000, which exposed a bug in the dib0700's
i2c implementation where it did not properly support a single i2c read request
(sending it as an i2c write request instead).  Version 1.20 of the firmware
added support for a new i2c API which supported such requests.

This change defaults to fw 1.20 for all devices, but does not default to using
the new i2c API (since initial testing suggests problems interacting with the
mt2060).  Maintainers can enable the use of the new i2c API by putting
the following into their frontend initialization:

struct dib0700_state *st = adap->dev->priv;
st->fw_use_new_i2c_api = 1;

Also note that the code expects i2c repeated start to be supported.  If the
i2c slave does not support repeated start, i2c messsages should have the
I2C_M_NOSTART flag set.

Thanks to Patrick Boettcher <patrick.boettcher@desy.de> for providing new
firmware fixing the issue as well as example i2c code utilizing the interface.

13c97bf567 V4L/DVB (8988): S2API: Allow the properties to call legacy ioctls
SET_TONE and SET_VOLTAGE were not previously implemented. Two options
existed. Either cut/paste from the previous ioctl handler into the
process_properties function, which is code duplication. Or, split
the current ioctl handler into it's two major pieces.

Piece 1, responsible for input validation and semaphore acquiring
Piece 2 the processing of the previous ioctls

and finally, a new third pieces where the array of properties
is processed, and can freely call the legacy ioctl handler without
having to re-acquire the fepriv->sem semaphore. This is a clean approach
and ensures the existing legacy ioctls are processed as they were previously
(but with an extra function call) and allows the new API to share code
without duplication.

6b73eeafbc V4L/DVB (8985): S2API: Added dvb frontend changes to support a newer tuning API
This is an experimental patch to add a new tuning mechanism for
dvb frontends. Rather than passing fixed structures across the
user/kernel boundary, which need to be revised for each new modulation
type (or feature the kernel developers want to add), this implements
a simpler message based approach, allowing fe commands to be broken
down into a series of small fixed size transactions, presented
in an array.

The goal is to avoid changing the user/kernel ABI in the future, by
simply creating new frontend commands (and sequencies of commands) that
help us add support for brand new demodulator, delivery system or
statistics related commmands.

known issues:
checkpatch voilations
feedback from various developers yet to be implemented, relating
to namespace conventions, variable length array passing conventions,
and generally some optimization.

This patch should support all existing tuning mechanisms through the
new API, as well as adding 8PSK, DVB-S2 NBC-QPSK and ISDB-T API support.

For testing and exercise purposes, see the latest tune.c tool
available from http://www.steventoth.net/linux/s2
