I2C detection

MINISASTOCSI camera chip is connected via I2C3. The most important address for correct detection is 0x3c.

root@imx8mq-voipac:~# i2cdetect -y 2
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: UU UU UU UU -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- UU -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

MINISASTOCSI camera can be also connected to I2C2 interface by moving 0R resistors. However second camera connected on CSI-2 interface have same address 0x3c as MINISASTOCSI camera connected on CSI-1 interface. CSI1-I2C2 and I2C3.png
