Hello,
To bring-up a new panel, first please confirm hardware is ready.
Then make some changes in software, including DTS and panel driver. Besides, it will be helpful to add some debug code in DSI driver to make sure configuration is correct.
panel-a-wuxga-8-0 is just a reference for your driver development.
For DTS part, there are a lot of documents in internet. You can start from sample code first.
