f5174af201 V4L/DVB (6698): pvrusb2: Implement signal routing schemes
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.

681c739944 V4L/DVB (6691): pvrusb2: Rework pipeline state control
This is a new implementation for video pipeline control within the
pvrusb2 driver.  Actual start/stop of the pipeline is moved to the
driver's kernel thread.  Pipeline stages are controlled autonomously
based on surrounding pipeline or application control state.  Kernel
thread management is also cleaned up and moved into the internal
control structure of the driver, solving a set up / tear down race
along the way.  Better failure recovery is implemented with this new
control strategy.  Also with this change comes better control of the
cx23416 encoder, building on additional information learned about the
peculiarities of controlling this part (this information was the
original trigger for this rework).  With this change, overall encoder
stability should be considerably improved.  Yes, this is a large
change for this driver, but due to the nature of the feature being
worked on, the changes are fairly pervasive and would be difficult to
break into smaller pieces with any semblence of step-wise stability.

c5a69d57eb Storage class should be before const qualifier
The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the
beginning of the declaration specifiers in a declaration is an
obsolescent feature.

d855497edb V4L/DVB (4228a): pvrusb2 to kernel 2.6.18
Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner.

The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded
cx23416 hardware MPEG2 encoder.  There are two major variants of this
device; this driver handles both.  Any V4L2 application which
understands MPEG2 video stream data should be able to work with this
device.
