This series introduces a simulated MIPI DSI panel.
Currently, the only way to validate DSI connectors is with a physical
panel. Since obtaining physical panels for all possible DSI configurations
is logistically infeasible, introduce a way for DSI drivers to simulate a
panel.
This will be helpful in catching DSI misconfiguration bugs and catching
performance issues for high FPS panels that might not be easily
obtainable.
For now, the simulated panel driver only supports setting customized
modes via the panel_simlation.mode modparam. Eventually, we would like
to add more customizations (such as configuring DSC, dual DSI, etc.).
