will have to wait at least until 3.4.
Interestingly, Javier Martin has fixed field_count handling in mx2_camera,
but, apparently, it also has to be fixed in other soc-camera drivers. So,
a patch for that might follow later in the 3.3 cycle.
The following changes since
As V4L2 specification states, frame_count must also

This patch adds a mechanism to increment the frame

Sure, we can support

But AFAIK, soc-camera does not support passing such kind of information.
Neither any of the host camera drivers currently available expect that

The mx2_camera needs some code to forward calls to S_INPUT/S_ROUTING to
tvp5150, in order to set the pipelines there.
This sounds like a sensible solution I will work on that soon.
Regards.

Hi Mauro,
regarding
These callbacks allow a host video driver
to poll video formats supported by tvp5150.

Is this behavior expected? What could we do to avoid frame loss?
Thank you.

This patch uses channel 2 of the eMMa-PrP to convert
format provided by the sensor to YUV420.
This format is very useful since it is used by the
internal H.264 encoder.

The driver creates a V4L2 subdevice. It currently supports cropping, gain,
exposure and v/h flipping controls in monochrome mode with an

Changes since v3:
Patch order inverted as requested by Mauro.
Now adjusting of the image dimensions is made using v4l_bound_align_image().
Some coding style fixes.

eMMa-PrP device included in Freescale i.MX2 chips can also
be used separately to process memory buffers. This patch
provides arch glue code for the driver which provides this
functionality.

better if the ivtv driver would continue to support the old
ioctl for the few years we still have any PVR350 user.

_REGISTER_CLOCK(imx27-fec.0, NULL, fec_clk)
_REGISTER_CLOCK(NULL, emi, emi_clk)
If I do that, mx2_camera.c will stop working.
Furthermore it does not work for this driver either (I get an error on
clk_get() ).

i.MX2x SoCs have a PrP which is capable of resizing and format
conversion of video frames. This driver provides support for
resizing and format conversion from YUYV to YUV420.
This operation is of the utmost importance since some of these
SoCs like i.MX27 include an H.264 video codec which only
eMMa-PrP device included in Freescale i.MX2 chips can also
be used separately to process memory buffers.
Changes since v2:
- Define imx_add_mx2_emmaprp function which also registers device,
not only alloc.
- Change definition of emma_clk.
- Minor fixes.

Changes since v2:
- Use devres to simplify error handling.
- Remove unused structures.
- Fix clock handling.
- Other minor problems.
