I like to know the purpose of the regulators in the ov5640_mipi.c driver module. There are three regulators described in dtb
DOVDD-supply = <®_1p8v>;
AVDD-supply = <®_2p5v>;
DVDD-supply = <®_1p8v>;
What function do they do ? does this powers the camera module? I could only see 5V supply going to the camera module in schematics (Wandboard-dual). If my camera module is powered externally do i need these lines ?
