+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
