Hello Manuel,

a few more things I noticed:

This LED is supplied by VCC5V_MIDU, so maybe this should be a regulator-led
supplied by gpio (FLASH_LED_EN_H) controlled regulator-fixed named f_led which
is in turn supplied by VCC5V_MIDU.

This regulator is supplied by vcc_bat: https://megous.com/dl/tmp/4ec71a4a2aea9498.png

There's no vdd1v2_dvp in the schematic on the camera sensor connector, or elsewhere:

So I guess, you can drop this, entirely. Maybe it's VDD1V5_DVP but I don't think
it needs to be described in DT, since it's pretty local to this camera sensor,
and nothing else uses it.
