Maybe this helps as well:

root at letux:~# lsmod|fgrep isp
omap3_isp             112112  0 
videobuf2_dma_contig     8519  1 omap3_isp
videobuf2_v4l2         15241  1 omap3_isp
videobuf2_core         30282  2 omap3_isp,videobuf2_v4l2
v4l2_common             5604  2 omap3_isp,ov9650
videodev              159855  5 v4l2_common,omap3_isp,videobuf2_core,ov9650,videobuf2_v4l2
media                  25675  3 omap3_isp,videodev,ov9650
root at letux:~# lsmod | fgrep ov9650
ov9650                 13442  0 
v4l2_common             5604  2 omap3_isp,ov9650
videodev              159855  5 v4l2_common,omap3_isp,videobuf2_core,ov9650,videobuf2_v4l2
media                  25675  3 omap3_isp,videodev,ov9650
root at letux:~# 

and

http://omappedia.org/wiki/Camera-ISP_Driver#Testing

which describes that /dev/media0 should exist...

So I conclude that the ISP driver is not properly initialized or configured.

Or something has changed in 4.8 which is not descibed on omappedia.

BR,
