Help text

Preload default EDID (Extended Display Identification Data) branded by Linux Foundation that exposes display modes up to 4k@30Hz, which have best compatibility with HDMI transmitters.

Enabling this option is recommended for a non-production use-cases. It will make driver usable out-of-the-box.

For a higher display modes you will need to load customized EDID from userspace using v4l2-ctl tool or by other means.

Without enabling this option driver will be practically non-functional until EDID will be loaded from userspace. Which is a wanted behavior when using this driver in a commercial product that should utilize own branded EDID.
