About Hailo15h HDMI

Hi.
I’m trying to implement HDMI output from a camera input from Hailo15h SBC.
The SBC board is equipped with a “lontium,lt9611uxc” chip.
However, there is no kernel data tree (dts).
I’m trying to do it my way, but it doesn’t work.
Hail said it was possible in 3Q, but it’s not in the latest release.
If anyone has implemented it, please help.
