Hi Guennadi, I wonder the difference with pixelcode mediabus and v4l2_colorspace. In mt9m001.c subdev driver, the "format" seems be determined using the combination pixelcode & colorspace. In the previous kernel version(before using Media Controller), somtimes the pixelformat is used for defining format of isp device. But, I gonna change to use Media Controller. So, can you tell me where I find about Media Controller, especially pixelcode and colorspace? Thanks.
