* Nextchip NVP6158 AHD to BT656/BT1120 decoder
Required Properties:
- compatible: should be "nvp6158-v4l2"
- clocks: reference to the Single 27M Oscillator.
- clock-names: should be "xvclk".
- pwr-gpios: High active nvp6158 power gpio
- pwr2-gpios: High active ahd camera power gpio
- pwdn-gpios: High active nvp6158 pwdn gpio
- pwdn2-gpios: High active ahd camera pwdn gpio
- rst-gpios: High active nvp6158 reset gpio
- rst2-gpios: High active ahd camera reset gpio
Optional Properties:
- rockchip,dvp_mode: BT656 or BT1120 or BT656_TEST
- rockchip,channel_nums: channel nums, 1/2/4
- rockchip,dual_edge: dual edge, 0/1
NVP6158 device address 0x30(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.
