Hi,
I ran into a problem while trying to get a Microsoft LifeCam
Studio(TM) (045e:0772) to work with uvccapture on a Raspberry PI
running Kernel 3.6.11 under Debian Wheezy.
I started grabbing a picture with:

Hi all,
Just in case someone has time to work on this: I thought I'd write down some
of the ideas I have to improve the streaming code in v4l2-ctl:
1) Add an option to select between limited and full range colors.
2) Add more test patterns:
- solid colors: black, white, red, green,

This patch series includes some cleanups of the recently added FIMC-IS

easier to reuse in the future exynos5-is driver.

Move the sub-device group ID definitions to the driver's public header

Get the sensor subdev by walking media graph in both cases: when the

to not dereference the pipeline-subdevs[] array and makes the module
more generic and easier to re-use in other media driver.

Make the sensor subdevs host_data hold a pointer to struct fimc_source_info,
which is defined in the driver's public header, rather than a pointer to
struct fimc_sensor_info which is specific to exynos4-is media device driver.
The purpose of this change is to allow easier reuse of the fimc-lite

monotonic clock (as all drivers should use).
I've tested this on actual hardware, and I hope to post more fixes for this
driver for 3.11. But I'd

This is a static checker where it complains if we check for one function
pointer and then call a different function on the next line.
In most cases, the code does the same thing before and after this patch.
For example, when -phase_diversity is non-NULL then -phase_div_status
is also non-NULL.

as well.

Hi Guennadi,
Typical video devices like camera sensors require an external clock source.
Many such devices cannot even access their hardware registers without a
running clock. These clock sources should be controlled by their consumers.
This should be performed, using the generic clock
