[meta-freescale] Nitrogen6x w/ OV5642

[Sébastien Taylor]

I did previously have the module working in Yocto when I first setup the fsl-image-test.  I then spent a few days customizing a custom layer and porting our applications and when I returned to do more testing is when the camera was no longer working.  It does seem like it's a connection issue though I'm so far not having much luck on that front, but I did capture these logs showing the ov5642_probe failing (extended the debug log slightly).

But it would seem the problem is on my end.

ov5642_probe
camera_reset: power_gp=0x6, reset_gp=0x8 reset_gp2=0xab
mx6_csi0_powerdown: powerdown=0, power_gp=0x6
ov5642_read_reg: write reg error: reg=300a err=-5
ov5642_probe:cannot find camera retval -1 chip_id_high 0x0
ov5642_read_reg: write reg error: reg=300b err=-5
ov5642_probe:cannot find camera retval -1 chip_id_low 0x0
mx6_csi0_powerdown: powerdown=1, power_gp=0x6
