(ADV748x)Can we use CEC only?

Hi !

I have a question about ADV7482 CEC.

Although the ADV7482 has a CEC function, can I use only the CEC function with or without an HDMI input?

It was originally planned to use the HDMI port of SoC like the attached image, but since the SoC does not have the CEC function and the input side does not use the CEC function, we thought that we can use ADV7482 CEC function.

Is this possible?

If possible, please let me know the points.

After initial device setup, can you use CEC functions as usual?

Also our customer want to know this in few days.

So if you can answer to this question ASAP, it would help us so much!

Best regards
