Does it support Color space conversion in fsl-L4.9.11 kernel?

[liangyan]

_ipu_dp_set_csc_coefficients() /drivers/mxc/ipu_disp.c,  i want to change CSC using ioctl method, but  it has no effect.

if i change  dp_csc_param.mode = -1 into  dp_csc_param.mode = DP_COM_CONF_CSC_DEF_BOTH, it has effective

so it does not support change CSC, in timely

试过了，不起作用，你们测试过？

默认驱动初始化过程中是关闭CSC功能的，

yes, this is tested version, another solution that you can use gstreamer, the command like:

Color Space Conversion (CSC)
"gst-launch-1.0 videotestsrc ! video/x-raw,format=NV12 ! imxvideoconvert_ipu ! video/xraw,
format=RGB16 ! ximagesink display=:0"
