DEars,

 

I have a question to better understand and use the video capture part of the imx6Q.

 

I can see in driver /media/video/imx/capture that i have ov5642.c driver (it configure I"c interface to the sensor, init register, etc etc... if mipi set up also the mipi interface).

then I have several layers (CIS, IPU , etc) the the last one I suppose is the V4l_imX)_capture

 

First question is:

1) is there any schematic block to better understand the relationship between them?)

2) all of that layer has their own ioctls... how i can specify wich one i want to use. (i.e the mirror or rotate can be done by IPU or by sensor itself.... how i can say from V4L2 to use that ioctl or that other....)?

 

Thanks

Omar Pighi
