Prefer the gspca sonixj driver for the Philips SPC600NC webcam instead of
the sn9c102 driver. As we've got userreports that it works with the gspca
driver, whereas it fails with the sn9c102 driver, see:

The code in the new sq905c.c is based upon the structure of the code in
gspca/sq905.c, and upon the code in libgphoto2/camlibs/digigr8, which supports
the same set of cameras in stillcam mode. I am a co-author of gspca/sq905.c and
I am the sole author of libgphoto2/camlibs/digigr8, which is licensed under the

gspca/sq905c.c.

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.

Remove ancient IVTV_IOC_G_CODEC and IVTV_IOC_S_CODEC ioctl functions
from the pvrusb2 driver. These are very very old, were non-standard,
and were only present to keep MythTV happy (their implementation did
nothing except to report success). That was long ago; no recent
versions of MythTV should require this anymore.

This change removes the old i2c module controlling layer from the
pvrusb2 driver. This is code that first had appeared in the driver
back in December 2005. It's history. Now we use v4l2-subdev. Please
note also that with this change, the driver will no longer be usable
in kernels older that 2.6.22.

The v4l2-subdev infrastructure requires that an initialization call
must be issued to all attached sub-devices before normal operation can
start. This change satisfies that requirement.

When a pvrusb2 driver instance first initializes, we need to be sure
to send out a complete state update for everything to all attached
modules. The old i2c layer did this by keeping a separate mask of
"stale" bits for each attached module - and setting that mask to all
stale when that module attaches. But the new sub-device adaptation
I've implemented here no longer has per-module stale bits. So instead
there's now a global "force dirty" bit that is set upon instance
initialization, before the sub-devices are attached. After the first
update, this bit is cleared, allowing for normal update-on-dirty
behavior. In this manner, we ensure that all sub-devices have been
properly synchronized at initialization.

The sub-device update mechanism relies on various "dirty" bits in the
driver in order to know what pieces of state need to be propagated out
to the various sub-devices. But that won't work if the dirty bits are
cleared before the update gets a chance to run. This change ensures
that the update takes place before the dirty bits are cleared.

A sub-device won't successfully attach to our I2C adapter if its class
isn't set to zero. Right the class is still set to
I2C_CLASS_TV_ANALOG in order to allow the old mechanism to still
work. This change temporarily sets the class to zero during the
interval when the sub-device attaches. This code will get removed
when the old i2c layer is finally removed from the driver.

The pvrusb2 driver had previously been using i2c module specific calls
to set the sample rate (a long long time ago this was needed). These
days it is safe to use a broadcast so let's just broadcast this when
communicating audio sample rate to sub-devices.

Lay down a foundation whereby it becomes possible to send customized

The pvrusb2 driver has a function that reports internal state. It can
be accessed from either the debug interface or as the result of a v4l
log status request. This change adds information listing sub-devices
to the report.
