px30 evb mini v11 20190507 camera issue ov5695

[Tommaso Merciai]

Hi Heiko,
Sorry for the first mail, I send you twice because invalid I set an
invalid Subject.

I'm working on px30 mini evb v11 20190507, in particular on camera side. I
see your patch on dts to support ov5695 camera. Once I have enabled the
right config:

CONFIG_VIDEO_OV5695=y

I'm not able to probe the ov5695 camera correctly. In particular I got
the following error:

[    2.427936] ov5695 2-0036: Unexpected sensor id(000000), ret(-5)
[    2.438224] ov5695: probe of 2-0036 failed with error -5

Seem's that the camera is in reset, dumping bus 2 I got no address
from ov5695:

root at px30-evb:~# i2cdetect -y 2
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -

I'm missing something?

Thanks in advance.
Tommaso
