From: Németh Márton <nm127@freemail.hu>
The V4L2 ioctls usually return 0 when the operation was successful
and -1 in case of error. Currently VIDIOC_REQBUFS returns the
number of buffers which is redundant because this information is
available in count field of struct v4l2_requestbuffers. The
V4L2 API specification, revision 0.24 [1] explicitly specifies for
VIDIOC_REQBUFS that the return value shall be 0 on success.
The patch was tested with v4l-test 0.13 [2] with vivi driver.

This patch is for supporting the remote control of the Winfast TV2000
XP Global TV capture card. A case statement was added in order to
initialize the GPIO data structures as well as a case statement for
handling the keys correctly when pressed.
Thanks to Hermann and Mauro for all the help

When we capture signal from composite input offen lost and found syncro
sequence. In this case the MPEG coder hardware reset after each
lost/found event. The image has a lot of artefactes. This patch remove
hardware reset of MPEG encoder.
This is patch from our customer. I checked this.
With my best regards, Dmitry.

Hi All.
If video has a lot of changes in frame, MPEG encoder need more time for coding process.
Add new bigger timeout for encoder.

Remove the videobuf-dma-contig sync operation. Sync is only needed
for noncoherent buffers, and since videobuf-dma-contig is built on
coherent memory allocators the memory is by definition always in sync.

A regression was introduced in hg changeset 33810c734a0d, which resulted in
a kernel panic whenever the device was disconnected from USB. The call to
4l2_device_register() was overwriting the pointer for usb_set_intfdata(), so
when au0828_usb_disconnect() was called, the usb_get_intfdata() returned a
pointer to the v4l2_device instead of the au0828_dev structure.

Toggle the AI1 mux when changing the CX18_AUDIO_ENABLE register. It's hard to
reliably tell when we have written to this register successfully unless we
change some bits we know we can read back. The AI mux bits always read back
what we wrote to them, so force them to toggle whenever we have to write to
the register, so we can tell we wrote to the register successfully.
This change was prompted by users experiencing broadcast audio decoding
problems after the cx18 module loads for the first time.

Add code to verify the cx18-av-core digitizer firmware loads correctly. The
verification function reads back and compares the firmware bytes loaded
into the A/V core. The result of the verification is only used to log a
message in the system log.
This change was prompted by users with multiple card setups that have problems
with broadcast audio decoding the first time the cx18 module is loaded.

With the transition of soc-camera to become a platform driver and to the
v4l2-subdev framework the initialisation order becomes important. In case
of a static build clients (i2c) drivers have to be available when host
drivers are probed. Moving host drivers down in the Makefile achieves the
desired order.

Currently pcm990 camera bus-width management functions request a GPIO and never
free it again. With this approach the GPIO extender driver cannot be unloaded
once camera drivers have been loaded, also unloading theb i2c-pxa bus driver
produces errors, because the GPIO extender driver cannot unregister properly.
Another problem is, that if camera drivers are once loaded before the GPIO
extender driver, the platform code marks the GPIO unavailable and only a reboot
helps to recover. Adding an explicit free_bus method and using it in mt9m001
and mt9v022 drivers fixes these problems.
