Mauro Carvalho Chehab b13b47e0b5 [media] au0828: explicitly identify boards with analog TV
Right now, the au0828 driver uses .tuner to detect if analog
tv is being used or not. By not filling .tuner fields at the
board struct, the I2C core can't do decisions based on it.

So, add a field to explicitly tell when analog TV is supported.

No functional changes.

Mauro Carvalho Chehab 2930977ac5 [media] au0828: Fix DVB resume when streaming
When DVB is streaming and suspend is called, it will call
au0828_stop_transport(), with will clean the streaming flag.

Due to that, stop_urb_transfer() will be called twice,
causing an oops.

So, we need another flag to be used at resume, telling it
to restart DVB.

While here, add a logic at stop_urb_transfer() to prevent
it of being called twice, and convert the usb_streaming
flag into boolean.

Mauro Carvalho Chehab 83afb32aa9 [media] au0828: use pr_foo macros
Instead of using printk(KERN_foo, use pr_foo() macros.

No functional changes.

Note: we should do the same for dprintk(), but that would
require to remove the dprintk levels. So, for now, let's
not touch on it.

Mauro Carvalho Chehab 1a1ba95e80 [media] au0828: add suspend/resume code for V4L2
No timers should be enabled during suspend. So,
stop them. At resume time, we should do the proper
initialization for it to keep working.

Mauro Carvalho Chehab b799de75e0 [media] au0828: Add suspend code for DVB
The scheduled work should be cancelled during suspend.

At resume time, we need to set the frontend again. So,
add such logic to the driver.

Define au0828_rc_*() stubs to avoid compile errors when
VIDEO_AU0828_RC is disabled and avoid the need to enclose
au0828_rc_*() in ifdef CONFIG_VIDEO_AU0828_RC in .c files.

Mauro Carvalho Chehab f6fef86341 [media] au0828: reset streaming when a new frequency is set
As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.

I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.

Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.

There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.

One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.

This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.

A complete fix, however, would also need to check the PM
conditions for the tuner and demux.

Tim Mester f251b3e78c [media] au0828: Add option to preallocate digital transfer buffers
Added command line parameter preallocate_big_buffers so that the digital
transfer buffers can be allocated when the driver is registered. They
do not have to be allocated every time a feed is started.

Tim Mester 4609981f84 [media] au8028: Fix cleanup on kzalloc fail
Free what was allocated if there is a failure allocating
transfer buffers.

Stop the feed on a start feed error.  The stop feed is not always called
if start feed fails.  If the feed is not stopped on error, then the driver
will be stuck so that it can never start feeding again.

Michael Krufky 8a4e786660 [media] au0828: remove forced dependency of VIDEO_AU0828 on VIDEO_V4L2
This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by
creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog
video capture support and depends on VIDEO_V4L2 itself.
With VIDEO_AU0828_V4L2 disabled, the driver will only support digital
television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2
enabled, the driver will be built with the analog v4l2 support included.
By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to
preserve the original behavior.
