This adds a flag in the device attribute structure which can be used
to mark support for a particular device as experimental. Any devices
flagged in this way, when encountered at run-time, will generate a
warning message to the kernel log.

New FX2 firmware from Hauppauge is no longer 8KB in size - it's 16KB.
This is true for HVR-1950 and HVR-1900 devices. Without this change,
new pvrusb2 users with that hardware are unable to use the driver
(because the CD shipped with the hardware only has the 16KB firmware).

the device
This change defines all possible "IR schemes" related to the pvrusb2
driver, on a per-device basis. That information is then set according
to the hardware in use. The idea here is to make possible a more
intelligent future decision on which, if any, IR receiver driver might
be loaded during initialization.

Forgot to include the tda9887 component when moving to v4l2-subdev. I
got fooled because its name is "tuner", the same as the tuner module.
Silly me.

Set up new mechanism for declaring and loading appropriate sub-devices
when driver initializes. This is another part of the v4l2-subdev

The Zilog IR chip on HVR-1900 devices is held in reset when the device
initializes. We have to bring this chip out of reset before LIRC has
any chance of operating the chip. So do it.

Single-bit signed bitfields can only take 0/-1 rather than 0/1 as the
drivers seems to assume...add unsigned.

Some tuners seem to not work in digital mode unless the encoder is
healthy. Implement a device attribute to represent this flag and
modify the core state machines to enforce this requirement.

When the DVB interface is not compiled, the pvr2_dvb_props struct is
not available - so it really should be ifdef'ed out as well. This
didn't cause an error because in this context its usage was as an
opaque pointer. But it really shouldn't be present at all if DVB is
not enabled.

Add basic framework for the DVB API. This is enough to control the
tuner & demod of the digital frontend, but the stream & buffer handling
is still missing.
Additional note from Mike Isely <isely@pobox.com> - also, since these
changes are still very experimental arrange for DVB changes to be
compiled in via new CONFIG_VIDEO_PVRUSB2_DVB option, for now.

The pvrusb2 driver has used hardcoded logic to control the LED on the
device. However this is really Hauppauge-specific behavior. This
change defines a new device attribute for LED control and sets things
up appropriately for Hauppauge devices.

Unlike analog control, control of the digital side is not nearly as
uniform among different devices. So we have to specify the correct
digital control scheme as a new device attribute.

Different devices support different input types. Up until now we've
really been assuming that everyone has an analog tuner, an FM radio,
composite, and s-video inputs. But as we add other devices, these
assumptions are no longer true. The way to deal with this is to
define the available inputs as additional device attributes, so that
the driver can adjust its internal behavior accordingly.

The pvrusb2 driver tries to keep all device specific attributes in a
single data structure in one source file. This change further cleans
up how that table is set up. We now try to group everything together
for each specific device, and the number of symbols exported from this
module has now been reduced to a single global.

This changeset allows the pvrusb2 driver to operate a new device type
("GOTVIEW USB2.0 DVD2"). Changes amount to defining a new routing
scheme for the device and adding appropriate table entries into

For Hauppauge 24xxx devices, the IR receiver is a custom piece of
logic that is very specific to the device. The pvrusb2 driver can
virtualize this to make it look like a more normal IR receiver found
in other Hauppauge devices. The decision of whether or not to enable
this virtualization however is a device-specific attribute, thus this
changeset.

The exact routing of video and audio signals within a device is a
device-specific attribute. Hauppauge devices do it one way; other
types of device may route things differently. Unfortunately it is
rather impractical to define chip-specific routing at the device
attribute level, so instead what happens here is that "schemes" are
defined. Each chip level interface implements its part of a given
scheme and the scheme as a whole is made into a device specific
attribute controlled via a table entry in pvrusb2-devattr.c. The only
scheme defined here is for Hauppauge devices, but clearly this opens
the door for other possibilities to follow.

attribute
Arrange so that the pvrusb2 driver can optionally work without a
Hauppauge ROM being present - which is fairly important for devices
that happen to not come from Hauppauge. The expected existence of a
Hauppauge ROM is now a device attribute. The tuner type is now also a
device attribute, which is consulted if there is no ROM.

The pvrusb2 driver currently supports two variants of the Hauppauge
PVR USB2. However there are other hardware types potentially
supportable, but the driver at the moment is not structured to make it
easy to describe these minor variations. This changeset is the first
set of changes to make such additional device support possible.
Device attributes are held in several tables all contained within
pvrusb2-devattr.c; all other device-specific driver behavior now
derives from these tables.
