Tuner, DVB frontend and video helper chip drivers are by default
autoselected by their respective host cards, this, however, doesn't make
much sense on SoC-based systems. Disable autoselection on EMBEDDED
systems.

The exchanges for sensor mt9v111 are different with bridges zc301 and zc303.
The exchanges for the bridge zc303 were those of the bad named tas5130ck.
These mt9v111 exchanges have been adjusted from the ms-Windows public files
vm30x.inf (for 0ac8:301b) and usbvm303.inf (for 0ac8:303b).

Some webcams as ov511 may find many times an end of image.
In this case, with the last patch in image concatenation
(commit 799b1bd41f398054d46fd35f73abd01c4009f6ca),
the image pointer was NULL and the system crashed in memcpy().

Corrupted video frames are dropped by default by the driver for
uncompressed formats. Data corruption is not less problematic for
compressed formats, so frame drop should be enabled by default for those
formats as well.
Mark buffers as faulty when an isochronous packet loss is detected for
any format, or when the buffer length doesn't match the image size for
uncompressed formats. Drop erroneous buffers regardless of whether the
format is compressed or uncompressed.

ir_raw_event
The CX23885 and CX25840 modules were using their own simple
IR pulse width measurement record type which required conversion
when passing to the new IR core. This change makes that record type
consistent with the new IR core and removes a data conversion.

Instead of reporting an IR Rx timeout event as a ridiculously

The CX23885 IR controller was reported to cause an interrupt storm
on a TeVii S470 card, but was reported fine on an HVR-1250. Keep
integrated IR disabled by default on CX2388[57] based cards to avoid
a bad user experience in the general case.

Interrupts from the AV Core are best handled by a workqueue handler
since many I2C transactions are required to service the AV Core
interrupt. The AV_CORE PCI interrupt is disabled by the IRQ handler
and reenabled when the work handler is finished.

This patch encapsulates access to the PCI_INT_MSK register and
dev->pci_irqmask variable and protects them with a spinlock.
This is needed because both the hard IRQ handler and a workhandler
will need to manipulate the mask to disable the AV_CORE interrupt.

Add initial IR Rx support using the intergrated IR controller in the
A/V core of the CX23885 bridge chip.
This initial support is flawed in that I2C transactions should not
be performed in a hard irq context. That will be fixed in a
follow on patch.
The TeVii S470 support is reported to generate perptual interrupts
that renders a user' system nearly unusable. The TeVii S470 IR
will be disabled by default in a follow on patch.

AV core

This patch is primarily a port of the integrated IR controller code in
cx23885/cx23888-ir.c. Right now, only the CX2388[57] AV core will
really try to set up IR. This IR support, by design, still requires the
bridge driver to do final IO pin mux configuration and setup of the IR
controller parameters.
For the CX2388[578] chips, enabling the AV Core for IR also starts
sending Audio and Video interrupts to the bridge driver. For
CX2388[578] chips audio and video interrupts are ignored and
acknowledged when they happen.
IR interrupt handling and status logging is exluded for the CX23888
which does not have an IR controller on the AV core.
Note that experimentation reveals that the IR irq enables on the
CX23885 have an inverted logic sense. The CX23887 likely suffers from
the same quirk. For these chips, those irq enable bits are handled
as interrupt disables.

The CX2584x and related cores are multifunction subdevices with a number
of internal blocks that act as interrupt sources. Move the v4L2_subdev
interrupt_service_routine callback from v4l_subdev_ir_ops to
v4l2_subdev_core_ops, as the video and audio blocks of a CX2584x and
related cores can generate interrupts along with the IR block. This
change also makes sense for other subdev's that generate interrupts and
do not have an IR block.

inversion
There is a distinction on IR Tx for the CX2388[578] chips of carrier
sense inversion (space is a carrier burst and mark is no burst) and I/O
pin level inversion (0 is high output level, 1 is low output level).
Allow the caller to set these parameters distinctly as v4l2_subdevice
IR parameters. This permits the IR device to be configured and enabled
without the IR Tx LED being on during idle/space time due to an external
hardware level inversion
