Moving a bit forward: I found the i2c address for the camera module: 0x0c. The DTS description should be complete at this point (I hope).
UPD1: I got bamboozled by dw9714 device, which resides on this bus. It was its address. Investigating further.
UPD2: I have no idea where the frontal camera should reside. According to the schematics, it's on the i2c2 bus, but I can't probe anything other than dw9714 on address 0x0c, and ov5648 on address 0x36. Just for the sake of it, I probed all i2c busses and found nothing.
