* Sony IMX378 MIPI sensor

Required Properties:
- compatible: should be "sony,imx378"
- clocks: reference to the 24M xvclk input clock.
- clock-names: should be "xvclk".
- dovdd-supply: Digital I/O voltage supply, 1.8 volts
- avdd-supply: Analog voltage supply, 2.8 volts
- dvdd-supply: Digital core voltage supply, 1.2 volts
- reset-gpios: High active reset gpio

Attention:
IMX378 device address 0x1a(7bit);

The device node must contain one 'port' child node for its digital output
video port, in accordance with the video interface bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt.
