This patch adds support for DMABUF memory type in videobuf2. It calls relevant

For this version, the support is for videobuf2 as a user of the shared buffer;

dma-buf shared buffer is given at [1]]

Furthermore, it looks like this 'lock' was put in to prevent concurrent

functions of the image sensor should be disabled or set to fixed values.
According to the TechNote bit 2 and bit 9 in the register 0x20 must be
set in snapshot mode and unset for normal operation. This applies for
mt9v022 Rev.3 and mt9v024. Add required reg. 0x20 settings dependent on

attached DVB STBs and 1394 attached DVB cards from Digital Everywhere).
The L: linux-media and T: linux-media.git lines in this entry are
redundant to what scripts/get_maintainer.pl would show automatically but
I added them for folks who read MAINTAINERS directly. The "(firedtv)"
string is for those folks as well if they look for driver name rather
than file path.
The F: drivers/media/firewire/ pattern and the "FireWire media drivers"

While this file was always maintained, there was no explicit entry

There aren't many things happening at saa7134 side for a long time:
Driver works, and it is stable. When new patches are submitted,
they're new boards addition for hardware I don't have.
So, add a new entry with status equal to Odd fixes to better
reflect it.

[media] v4l2: Fix typo in struct v4l2_captureparm description
Judging from what drivers do and from my experience temeperframe
fraction is set in seconds - look e.g. here
static int bttv_g_parm(struct file *file, void *f,
struct v4l2_streamparm *parm)
{
struct bttv_fh *fh = f;
struct bttv *btv = fh->btv;

frameperiod->numerator = 1001;
frameperiod->denominator = 30000;
} else {
frameperiod->numerator = 1;
frameperiod->denominator = 25;
}
and also v4l2-ctl in userspace decodes this as seconds:
if (doioctl(fd, VIDIOC_G_PARM, &parm, "VIDIOC_G_PARM") == 0) {
const struct v4l2_fract &tf = parm.parm.capture.timeperframe;
...
printf("\tFrames per second: %.3f (%d/%d)\n",
(1.0 * tf.denominator) / tf.numerator,
tf.denominator, tf.numerator);
