Hans Verkuil f1b6a73532 [media] cx23885: Add busy checks before changing formats
Before you can change the standard or the capture format, make sure the
various vb2_queues aren't in use since you cannot change the buffer size from
underneath a a busy vb2_queue.

Also make sure that the return code of cx23885_set_tvnorm is returned
correctly, otherwise the -EBUSY will be lost.

Hans Verkuil 453afdd9ce [media] cx23885: convert to vb2
As usual, this patch is very large due to the fact that half a vb2 conversion
isn't possible. And since this affects 417, alsa, core, dvb, vbi and video the
changes are all over.

What made this more difficult was the peculiar way the risc program was setup.
The driver allowed for running out of buffers in which case the DMA would stop
and restart when the next buffer was queued. There was also a complicated
timeout system for when buffers weren't filled. This was replaced by a much
simpler scheme where there is always one buffer around and the DMA will just
cycle that buffer until a new buffer is queued. In that case the previous
buffer will be chained to the new buffer. An interrupt is generated at the
start of the new buffer telling the driver that the previous buffer can be
passed on to userspace.

Much simpler and more robust. The old code seems to be copied from the
cx88 driver. But it didn't fit the vb2 ops very well and replacing it with
the new scheme made the code easier to understand. Not to mention that this
patch removes 600 lines of code.

Luis Alves 5bc08e1921 [media] cx23885[v4]: Fix interrupt storm when enabling IR receiver
Apparently the Flatiron genereates an interrupt after the built-in self
test for each of its left and right channels has completed.

Apparently Conexant wire-OR'ed the Flatiron's interrupt output with the
interrupt output of the CX23885 A/V core.

Those interrupts need to be handled, otherwise, they generate an
interrrupt request storm.

So:

- Add flatiron readreg and writereg functions prototypes
  on a new header file;
- Modify the av interrupt handler to cleanup flatiron IRQs if no other
  interrupt handling happens.
