No video with HDMI DIP #4
Description
Hi, I am unable to get video with the HDMI DIP. The plymouth boot screen shows up, but then when the machine finishes booting up, the plymouth screen disappears and the monitor goes to sleep with No Signal. At that point, I can access the CHIP over SSH.
If I disable plymouth, there is no video whatsoever, the console never shows up either from u-boot or the kernel.
The monitor is detected over I2C, and the Chrontel CH7033 Video Encoder is detected by the kernel.

I'm running a stock bookworm armmp kernel, compiled using your instructions.
My monitor is a DIY monitor I made with a chromebook screen attached using a eDP to HDMI adapter, I tested it with a laptop and it works fine.
