Hi all.
I have a question about MIPI-CSI2 setting of i.MX6 linuxBSP.

 

Refer to Figure 19-1 "CSI2IPU gasket connectivity" i.MX6DQ Reference Manual (rev.2  7/2014),
VC0/VC1/VC2/VC3 assigned to IPU1_CSI0/IPU1_CSI1/IPU2_CSI0/IPU2_CSI1 respectively.

On the other hands. default setting in <linux>/arch/arm/mach-mx6/board-

mx6q_sabresd.c seems VC0 assigned to IPU1_CSI1 as following;

mipi_csi2_pdate={
    ipu_id = 0;
    csi_id = 1;
    v_channel = 0; ...

 

(Q) Which one is correct a) VC0 merely connect to IPU1_CSI0 or
    b) VC0 is one of choice for IPU1_CSI1?

 

If my assumptions were wrong, please let me know.

 

Thanks.
