Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer.
Add new member variables - bytesused, length, offset, userptr, fd,
data_offset - to struct vb2_plane in order to cover all information
of v4l2_plane.
struct vb2_plane {
<snip>
unsigned int bytesused;
unsigned int length;
union {
unsigned int offset;
unsigned long userptr;
int fd;
} m;
unsigned int data_offset;
}
Replace v4l2_buf with new member variables - index, type, memory - which
are common fields for buffer management.
struct vb2_buffer {
<snip>
unsigned int index;
unsigned int type;
unsigned int memory;
unsigned int num_planes;
struct vb2_plane planes[VIDEO_MAX_PLANES];
<snip>
};
v4l2 specific fields - flags, field, timestamp, timecode,
sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c
struct vb2_v4l2_buffer {
struct vb2_buffer vb2_buf;
__u32 flags;
__u32 field;
struct timeval timestamp;
struct v4l2_timecode timecode;
__u32 sequence;
};

When vb2_is_busy() it should still be possible to call S_DV_TIMINGS
provided the new timings are the same as the current timings.
For input 1 (test generator) the size is always 1080p, so just return
that.
Fixes a v4l2-compliance issue.

There are still some 64-bit division problems in the cobalt code.
Replace it by div_u64.

Simplify cobalt_g/try_fmt_vid_cap by not setting the colorspace fields in
pix again (since v4l2_fill_pix_format does that already), and by using
v4l2_fill_mbus_format in cobalt_s_fmt_vid_out which allows the get_fmt
call to be dropped as well.

Add support for the transfer function to the cobalt driver: make sure it is
passed on to/retrieved from the sub-device correctly.

The cobalt device is a PCIe card with 4 HDMI inputs (adv7604) and a
connector that can be used to hook up an adv7511 transmitter or an
adv7842 receiver daughterboard.
This device is used within Cisco but is sadly not available outside
of Cisco. Nevertheless it is a very interesting driver that can serve
as an example of how to support HDMI hardware and how to use the popular
adv devices.
