dmesg log

I tried to use an IR camera module, based on OV5647 device, but I fail to get
it working.
On top of Tumbleweed, I installed raspberrypi-firmware-extra and created
/boot/efi/extraconfig.txt with:
 # Camera IR ov5647
 start_x=1
 gpu_mem=128
 dtoverlay=ov5647
 # I2C
 dtparam=i2c_arm=on

On reboot, ov5647 and bcm2835_v4l2 kernel drivers are loaded, but no error is
displayed in dmesg and there is no /dev/video* devices.

'i2cdetect -l' retuns:
 i2c-0   i2c             i2c-11-mux (chan_id 0)                  I2C adapter
 i2c-1   i2c             bcm2835 (i2c@7e804000)                  I2C adapter
 i2c-2   i2c             bcm2835 (i2c@7e805000)                  I2C adapter
 i2c-10  i2c             i2c-11-mux (chan_id 1)                  I2C adapter
 i2c-11  i2c             bcm2835 (i2c@7e205000)                  I2C adapter

and 'i2cdetect -y 10' confirms that i2c address 36 is used by a driver, likely
ov5647:
      0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Any idea what I am missing?
