Laurent Pinchart d52e238136 [media] v4l: Support extending the v4l2_pix_format structure
The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.

To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.

The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.

To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

Hans Verkuil 2a9ec37311 [media] v4l2-ctrls: use ptrs for all but the s32 type
Rather than having two unions for all types just keep 'val' and
'cur.val' and use the p_cur and p_new unions to access all others.

The only reason for keeping 'val' and 'cur.val' is that it is used
all over, so converting this as well would be a huge job.

Mauro Carvalho Chehab 8abe4a0a3f [media] dib7000: export just one symbol
Exporting multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.

This were reported several times, like:

   drivers/built-in.o: In function `cxusb_dualdig4_rev2_tuner_attach':
>> cxusb.c:(.text+0x27d4b5): undefined reference to `dib7000p_get_i2c_master'

   drivers/built-in.o: In function `cxusb_dualdig4_rev2_frontend_attach':
>> cxusb.c:(.text+0x27df5c): undefined reference to `dib7000p_i2c_enumeration'

In this specific report:
	CONFIG_DVB_USB_CXUSB=y
	CONFIG_DVB_DIB7000P=m

But the same type of bug can happen if:
	CONFIG_DVB_DIB7000P=m
and one of the bridge drivers is compiled builtin (cxusb, cx23885-dvb
and/or dib0700).

As a bonus, dib7000p won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.

Tested with Hauppauge Nova-TD (2 frontends).

Mauro Carvalho Chehab 7f67d96ab1 [media] dib7000p: rename dib7000p_attach to dib7000p_init
Well, what we call as "foo_attach" is the method that should
be called by the dvb_attach() macro.

It should be noticed that the name "dvb_attach" is really a
bad name and don't express what it does.

dvb_attach() basically does three things, if the frontend is
compiled as a module:
- It lookups for the module that it is known to have the
  given symbol name and requests such module;
- It increments the module usage (anonymously - so lsmod
  doesn't print who loaded the module);
- after loading the module, it runs the function associated
  with the dynamic symbol.

When compiled as builtin, it just calls the function given to it.

As dvb_attach() increments refcount, it can't be (easily)
called more than once for the same module, or the kernel
will deny to remove the module, because refcount will never
be zeroed.

In other words, the function name given to dvb_attach()
should be one single symbol that will always be called
before any other function on that module to be used.

For almost all DVB frontends, there's just one function.

However, the dib7000p initialization can require up to 3
functions to be called:
	- dib7000p_get_i2c_master;
	- dib7000p_i2c_enumeration;
	- dib7000p_init (before this patch dib7000_attach).

(plus a bunch of other functions that the bridge driver will
need to call).

As we need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.

So, let's rename the function that probes and init the hardware
to dib7000p_init.

A latter patch will add a new dib7000p_attach that will be
used as originally conceived by dvb_attach() way.

Hans Verkuil 2ada815fc4 [media] saa7134: convert to vb2
Convert the saa7134 driver to vb2.

Note that while this uses the vb2-dma-sg version, the VB2_USERPTR mode is
disabled. The DMA hardware only supports DMAing full pages, and in the
USERPTR memory model the first and last scatter-gather buffer is almost
never a full page.

In practice this means that we can't use the VB2_USERPTR mode.

This has been tested with raw video, compressed video, VBI, radio, DVB and
video overlays.

Unfortunately, a vb2 conversion is one of those things you cannot split
up in smaller patches, it's all or nothing. This patch switches the whole
driver over to vb2, using the vb2 ioctl and fop helper functions.

Hans Verkuil 17e7f1b515 [media] saa7134: fix regression with tvtime
This solves this bug:

https://bugzilla.kernel.org/show_bug.cgi?id=73361

The problem is that when you quit tvtime it calls STREAMOFF, but then it queues a
bunch of buffers for no good reason before closing the file descriptor.

In the past closing the fd would free the vb queue since that was part of the file
handle struct. Since that was moved to the global struct that no longer happened.

This wouldn't be a problem, but the extra QBUF calls that tvtime does meant that
the buffer list in videobuf (q->stream) contained buffers, so REQBUFS would fail
with -EBUSY.

The solution is to init the list head explicitly when releasing the file
descriptor and to not free the video resource when calling streamoff.

The real fix will hopefully go into kernel 3.16 when the vb2 conversion is
merged. Basically the saa7134 driver with the old videobuf is so full of holes it
ain't funny anymore, so consider this a band-aid for kernels 3.14 and 15.

Hans Verkuil e37559b22c [media] vb2: stop_streaming should return void
The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.

The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.

The pwc amd sdr-msi3101 drivers both had this construction:

        if (mutex_lock_interruptible(&s->v4l2_lock))
                return -ERESTARTSYS;

This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

Daniel Glöckner c8204930b2 [media] bttv: Add support for PCI-8604PW
This patch adds support for the PCI-8604PW card equipped with four 878A.
It is unknown who the manufacturer of this card is and no drivers were
available during development of the patch. According to images found
online, the card is originally sold with Linux DVR software.

A CPLD on the card prevents the 878A from requesting access to the
bus until an initialization sequence has been issued via GPIOs. The
implemented sequence uses the minimum number of GPIOs needed to
successfully unlock bus access. As there are many more GPIOs connected
to the CPLD, it is very likely that some of the others have an influence
on the bus arbitration scheduling. This should be investigated further
in case of performance issues.

The tested card contains an EEPROM on one of the 878A, but it is
completely empty (i.e. contains only 0xff), so it is not possible
to detect the card.

Hans Verkuil 30d652823d [media] saa7134: fix WARN_ON during resume
Do not attempt to reload the tuner modules when resuming after a suspend.
This triggers a WARN_ON in kernel/kmod.c:148 __request_module.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=69581.

This has always been wrong, but it was never noticed until the WARN_ON
was added in 3.9.

Dan Carpenter cdcb12e78a [media] ddbridge: remove unneeded an NULL check
Static checkers complain about the inconsistent NULL check here.

There is an unchecked dereference of "input->fe" in the call to
tuner_attach_tda18271() and there is a second unchecked dereference a
couple lines later when we do:
	input->fe2->tuner_priv = input->fe->tuner_priv;

But actually "intput->fe" can't be NULL because if demod_attach_drxk()
fails to allocate it, then we would have return an error code.

Hans Verkuil 9c0863b1cc [media] vb2: call buf_finish from __queue_cancel
If a queue was canceled, then the buf_finish op was never called for the
pending buffers. So add this call to queue_cancel. Before calling buf_finish
set the buffer state to PREPARED, which is the correct state. That way the
states DONE and ERROR will only be seen in buf_finish if streaming is in
progress.

Since buf_finish can now be called from non-streaming state we need to
adapt the handful of drivers that actually need to know this.
