In am437x-vpfe.h BASE_VIDIOC_PRIVATE is used for
making the name of ioctl command(VIDIOC_AM437X_CCDC_CFG).
The definition of BASE_VIDIOC_PRIVATE is in linux/videodev2.h.
However, linux/videodev2.h is not included in am437x-vpfe.h.

am437x-vpfe.h and linux/videodev2.h.

With this patch, the application can include just am437x-vpfe.h.

[media] vb2: check if vb2_fop_write/read is allowed

Return -EINVAL if read() or write() is not supported by the queue. This
makes it possible to provide both vb2_fop_read and vb2_fop_write in a
struct v4l2_file_operations since the vb2_fop_* function will check if
the file operation is allowed.

A similar check exists in __vb2_init_fileio() which is called from
__vb2_perform_fileio(), but that check is only done if no file I/O is
active. So the sequence of read() followed by write() would be allowed,
which is obviously a bug.

In addition, vb2_fop_write/read should always return -EINVAL if the
operation is not allowed, and by putting the check in the lower levels
of the code it is possible that other error codes are returned (EBUSY
or ERESTARTSYS).

All these issues are avoided by just doing a quick explicit check.

the 'active' formats, the enum ops didn't have that option and always used

on the active format.

So add a new 'which' field to these structs. Note that V4L2_SUBDEV_FORMAT_TRY
is 0, so the default remains TRY (applications need to set reserved to 0).

[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config

If a subdevice pad op is called from a bridge driver, then there is
no v4l2_subdev_fh struct that can be passed to the subdevice. This
made it hard to use such subdevs from a bridge driver.

This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config
pointer in the pad ops. This allows bridge drivers to use the various
try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it
along to the pad op.

The v4l2_subdev_get_try_* macros had to be changed because of this, so
I also took the opportunity to use the full name of the v4l2_subdev_get_try_*
functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do
'git grep v4l2_subdev_get_try_format' you will actually find the header
where it is defined.

One remark regarding the drivers/staging/media/davinci_vpfe patches: the
*_init_formats() functions assumed that fh could be NULL. However, that's
not true for this driver, it's always set. This is almost certainly a copy
and paste from the omap3isp driver. I've updated the code to reflect the
fact that fh is never NULL.

[media] media: radio: assign wait_for_completion_timeout to appropriately typed var

wait_for_completion_timeout() returns unsigned long not int. This assigns
the return value to an appropriately typed variable (also helps keep
static code checkers happy).

[media] vivid sdr: fix broken sine tone generated for sdr FM

FM (frequency modulated) signal for SDR is generated by varying the
phase, where phase variation is proportional to input signal. It is
seen that, the larger phase increments leads to discontinuities in
the signal recovered after demodulation. Reducing the extent of phase
variation with respect to input signal, equivalent to reducing the
modulation index.

Tested using FM receiver flow graph in gnuradio-companion.
