IMX6 OV5640 MIPI camera

Hi All,

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 = <&reg_1p8v>;
AVDD-supply = <&reg_2p5v>;
DVDD-supply = <&reg_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 ?
