Hi everyone.

In my case, not use camera. just use csi0 driver(mxc_v4l2_capture) and ov5640 camera driver and app.

ov5640 driver set image is below

	ov5640_mode_VGA_640_480
	ov5640_mode_QVGA_320_240
	ov5640_mode_NTSC_720_480
	ov5640_mode_PAL_720_576
	ov5640_mode_720P_1280_720
	ov5640_mode_1080P_1920_1080
	ov5640_mode_QSXGA_2592_1944
	ov5640_mode_QCIF_176_144
	ov5640_mode_XGA_1024_768

If i want to add size 6144 X 3072 , how to change code?

According to the manual(IMX6SDLRM : 2818p, 2877p ) that can

change elements (sensor frame width (height)and active frame width(height) and clock(F=FH*FW*FPS*BI*DF) )

I don't know. what files are check .I already check like that mxc_v4l2_capture.c(in kernel) , ov5640.c(in kernel), ,ipu_capture.c ,ipu_regs.h(in linux/ipu3) ..

How to check and modify correct files?
