The ASUS A6VM notebook has a built in stk11xx webcam which is mounted
in a way that the video is vertically and horizontally flipped.
Therefore this notebook is added to the special handling in the driver

usb_control_msg returns in case of a successfully sent message the number
of sent bytes as a positive number. Don't use this value as a return value
for stk_camera_read_reg, as a non-zero return value is used as an error
condition in some cases when stk_camera_read_reg is called.

Hi,
This series introduces the Media driver to work with the i.MX7 SoC. it uses the
already existing imx media core drivers but since the i.MX7, contrary to
i.MX5/6, do not have an IPU and because of that some changes in the imx media
core are made along this series to make it support that case.

Not all future supported video chips will always have power management
support, and so it is important to check before calling set_power() is
defined.

Add initial support for Melexis line of thermal cameras. This is the first part

Add initial support for MLX90640 thermal cameras which output an 32x24
greyscale pixel image along with 2 rows of coefficent data.
Because of this the data outputed is really 32x26 and needs the two rows
removed after using the coefficent information to generate processed
images in userspace.

Hello everyone
when we need to setup media pipeline, eg, for camera capture, media-ctl
needs to be called multiple time to setup media link and subdev
formats, or similar code in a single application. this will use
multiple IOCTLs on "/dev/mediaX" and "/dev/v4l2-subdevY".

Hans,
If you think the driver is now ready, I'd like to merge
only patches 1/4 and 4/4 (the driver per-se) via the media tree.
