Color space configuration in v4l2 sub device driver

Hi,

 

In v4l2 sub device driver, how to provide support for the color spaces which are not

defined by the v4l2(not defined in enum v4l2_colorspace)? For example Adobe RGB,

Adobe YCC 601, sYCC 601 etc.

 

http://www.hdmi.org/manufacturer/hdmi_1_4/color_spaces.aspx.

 

How user can specify the different ranges eg. RGB 0 to 255 or RGB 16 to 235?

 

How user can specify the output formats for which the Fourcc is not defined by the v4l2?

For example: DDR 4:4:4, SDR 4:2:2 - 2 channel etc.

 

Thanks and Regards,

Anil Ghadiya
