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

With video_nr, vbi_nr and radio_nr being simple integers, it is not
possible to use these parameters on a system with multiple bttv
adapters (which happens to be my case.) video_register_device() will
always fail on the second and later adapters. Turn these parameters
into arrays, as many other V4L drivers are already doing, so that they
can be used on such systems.

Dont pass devptr in xc5000_attach, dont store it in xc5000_priv.
This pointer is passed into the tuner_callback function, which always
expects a pointer to fe->dvb->priv or i2c_adapter->algo_data.
This prevents future possible bugs in new drivers, such as using a "devptr"
other that the standard fe->dvb->priv in a DVB driver.

Prevent an OOPS if xc5000_attach was called by tuner.ko before being called by
the DVB adapter driver. The OOPS occurs when a digital tune request is made
after tuner.ko is unloaded.
When tuner.ko is unloaded, it takes the xc5000_config structure with it.
Rather than storing a pointer to the xc5000_config structure, just store the
if_khz and tuner_callback inside the xc5000_priv internal state structure.

cx18: Throttle mmio to/from the CX23418 so boards work in older systems. The
CX23418 couldn't reliably handle mmio at the rate at which the cx18 driver was
attempting to access the chip. The PCI bridge arrangements and settings on
modern motherboards still allowed the CX23418 to work OK, but it didn't work
well on many older motherboards: mysterious I2C errors, firmware loading errors,
etc. This patch adds a throttle to *all* mmio access to the CX23418. It
defaults to a delay of 31 ns, but is adjustable by the mmio_ndelay module parm.

This builds upon the previous pvrusb2 change to more formally
implement full cropping support. This enables access from the
driver's V4L interface, and enables access to full capabilities from
sysfs as well. Note that this is only effective when in analog mode.
It also will only work when the underlying digitizer's driver (saa7115
or cx25840 depending on the hardware) also implements the appropriate
functions.
