 * We need setting some flags in bridge, and using them in encoder. Add them in

 * private_flags would be better for use. DRM_MODE_FLAG_SUPPORTS_RGB/YUV are

 * flags that indicating the SINK supported color formats read from EDID. While,

 * these flags defined here indicate the best color/bit depth foramt we choosed

 * that would be better for display. For example the best mode display like:

 * RGB+RGB_DC,YUV+YUV_DC, RGB,YUV. And we could not set RGB and YUV format at

 * the same time. And also RGB_DC only set when RGB format is set,the same for

 * YUV_DC.
