The purpose of the new field is to allow the video pipeline elements to

Hello,
This patch series tries to solve the issue presented in my other posting [1] by
extending the media bus format data structure with a new parameter, rather than
adding a new subdev video ops callback.
Although there are opinions [2] the 'framesamples' parameter should not be a
part
of
Use new struct v4l2_mbus_framefmt framesamples field to return maximum
size of data transmitted per single frame. The framesamples value is
adjusted according to pixel format and configured in the ISP registers.
Except the pixel width and height, the frame size can also be made
dependent on JPEG
The framesamples field of struct v4l2_mbus_framefmt is used to retrieve
an exact required maximum memory buffer size for a compressed data frame
from the sensor subdev. This allows to avoid allocating huge buffers
at the host driver.
To make sure the size of allocated buffers is correct for a

Hi Mauro,
This patch series adds support for per-device capabilities.
All comments from the previous RFC PATCH series have been incorporated and
the documentation has been updated.
As far as I am concerned it is ready to be merged for v3.3.
The git request-pull output is below:

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.

would be called before its remove function.
