Xceive has graciously allowed us to now freely redistribute the xc5000

from the Hauppauge driver.

Defer loading of the xc5000 firmware until it is actually needed. This helps
on distros that have hald, which results in the device not being available
for use for around ten seconds in cases where the i2c bus is slow (such as
the HVR-950Q). Also, the firmware load isn't really useful since we
immediately put the device to sleep afterward, which means a firmware reload
will be required anyway.

This switches to a new version of the xc5000 firmware, extracted from the

Bring back the code that puts the xc5000 to sleep. For the Pinnacle 801e
this results in power consumption at idle dropping from 325ma to 124ma.
If there are *actually* any devices that don't work in this configuration,
they should set dvb_frontend.ops.tuner_ops.sleep to NULL (per mkrufky's
suggestion)
Also, had to make sure we were making sure the firmware was loaded in the
digital version of set_params, or else we end up get i2c errors if the
device is asleep

The GPIO's on the product can be in one of three places. To date we've
mainly used the GPIO's on the bridge itself, and once on the encoder.
Rather than having the complexity of multiple GPIO writes/reads from
isolated placed in the driver we'll route them through this function,
so we can make intelligent decisions about 1) Where the GPIO lives
and 2) Whether it conflicts (based on board) with some other function
to avoid bugs.

Currently, DVB-T is broken and this fixes it.
The PVRUSB2 has an odd I2C bus configuration where opening the i2c gate
on the digital and analog demod causes the tuner to fail. This needs
to be protected against for the PVRUSB2.

The i2c core used to maintain a list of client for each adapter. This
is a duplication of what the driver core already does, so this list
will be removed as part of a future cleanup. Anyone using this list
must stop doing so.
For pvrusb2, I propose the following change, which should lead to an
equally informative output. The only difference is that i2c clients
which are not a v4l2 subdev won't show up, but I guess this case is
not supposed to happen anyway.

Kick up the pvrusb2 version number advertised through the v4l

make a serious attempt to version the driver in this manner (otherwise
this one line becomes a nasty hotspot of changes and merge
conflicts). The value that is here is really a historical thing.
However Hans Verkuil thought it might be a good idea to bump up the
number anyway right now since the driver's mechanism for communicating
with the v4l core has pretty much completely changed. Sending out a

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.
