[media] au0828: prevent i2c gate from being kept open while in analog mode

The original implementation of the analog support would use an
i2c_gate_ctrl function when using the digital side of the au8522, but on
the analog side we would always just force the gate open and leave it
open all the time.

This can have adverse effects on the xc5000 given the tuner is receiving
all the spurious i2c traffic (a problem which can be exaggerated due to
bugs in the au0828 i2c hardware implementation).

Rework the existing hack to only open/close the gate when actually
talking to the tuner.

This logic might need to be reworked a bit if anybody ever tries to add
support for a board that has the au0828/au8522 but doesn't have digital
support implemented (because the i2c_gate_ctrl callback is being set in

If the user performs a tuning attempt without explicitly calling the
s_std ioctl(), a value of zero is sent from tuner-core to xc5000.  This
causes the xc5000 driver to leave the standard unchanged.  The problem
was masked by the fact that the xc5000 driver defaulted to NTSC, but if
you happened to perform an ATSC/ClearQAM tuning attempt and then do an
analog tune, the net effect is an analog tune with the standard still
set to DTV6.

Keep track of whether the standard has ever been sent to tuner-core.  We
don't make an s_std subdev call explicitly during probe because that
will cause a firmware load (which is very time consuming on the 950q).

[media] au8522: properly recover from the au8522 delivering misaligned TS streams

There is an apparent bug in the au8522 TS clocking which can result in
it delivering a TS payload to the au0828 that is shifted by some number

38 FF F8" which if you shift left one bit is "1F 47 1F FF F0..."

This presents itself as no TS stream being delivered from the kernel to
userland, since the kernel demux will drop every packet.

In the event that this condition occurs, restart the DVB stream.

Also, this patch includes a couple of lines of cleanup to not change the
FIFO configuration while the FIFO is running (which can screw up the

[media] az6007: handle CI during suspend/resume

The dvb-usb-v2 core doesn't know anything about CI. So, the
driver needs to handle it by hand. This patch stops CI just
before stopping URB's/RC, and restarts it before URB/RC start.

It should be noticed that suspend/resume is not yet working properly,
as the PM model requires the implementation of reset_resume:
dvb_usb_az6007 1-6:1.0: no reset_resume for driver dvb_usb_az6007?
But this is not implemented there at dvb-usb-v2 yet.
