Hi,
Recently in TI and Nokia, we are working towards having for acceptance an OMAP3 camera driver, which uses an on-chip Image Signal Processor that has one feature of color effects. We were using a V4L2 private CID for that, but have been suggested that this could be common enough to propose to the V4L2 spec aswell for other devices to use.
Below patch adds the control to include/linux/videodev2.h file, should this be enough? (This patch is taking as a codebase the latest linux-omap kernel, which I believe is v2.6.28 still)
Thanks and Regards,
Sergio
