I working on interfacing own camera chip with iMX8M processor using linux kernel 4.14.78.
I have written the camera driver for chip and it probes successfully as a video subdevice.
In order to program the chip from the user application, i need to define some custom controls in my v4l2 sub-device driver As per the following link 1.7. V4L2 sub-devices — Linux Media Subsystem Documentation documentation , subdevice must get created in /dev/ directory but in my case i am not able to generate the subdevice nodes
Does iMX platforms support v4l2 subdevice creation for the video device...?
Can anoyne help me to create v4l2 subdevice entry for my camera driver...?
