ADV7282-M Linux Driver Select Input Issues


I'm using the driver with an ADV7282-M. This is a slightly modified version of the mainline Driver under

One of the modifications is that is switches to ADV7182_INPUT_CVBS_AIN1 after Init. This works fine, but seems to often cause video too dark/bright issues. See:

Commenting this switch to first input logic fixed the video too dark/bright issue. Next I tried to find the root cause.

The root cause seems to be the following register writes: I tried to find these registers in the ADV7180/7182/7280/7282 Datasheets but didn't find them.

Where are these registers from? I'm happy to provide a PR to fix this as soon as I understand where these registers are coming from..
