ADV7393 apalis IMX6 (toradex)

Hi,

I try to have NTSC/PAL output on ADV7393.

I drive the ADV7393 with a FPGA and the video with imx6 in RGB mode.

I use the last linux version 2.8b6 of toradex i have the driver for ADV7393. But i don't know how to use it... 

I check the ADV7393 video encoder in devicetree with make nconfig

"Device drivers/Multimedia support / I2C Encoders,decoders,sensor and other helper chips/ADV7393 video encoder"

I modify the files imx6qdl-apalis-eval.dtsi according to https://android.googlesource.com/kernel/msm/+/android-7.1.0_r0.2/Documentation/devicetree/bindings/media/i2c/adv7343.txt?autodive=0%2F%2F

nano ./arch/arm/boot/dts/imx6qdl-apalis-eval.dtsi 

        /* advanten add ADV7393 */
        adv7393@2a {
                compatible = "adi,adv7343";
                reg = <0x2a>;
                port {
                        adv7343_1: endpoint {
                                        adi,power-mode-sleep-mode;
                                        adi,power-mode-pll-ctrl;
                                        /* Use DAC1..3, DAC6 */
                                        adi,dac-enable = <1 1 1 0 0 1>;
                                        /* Use SD DAC output 1 */
                                        adi,sd-dac-enable = <1 0>;
                        };
                };



        };

But nothing appear on the i2c.

Someone could help me?
