From: David Heidelberg <[email protected]> Initial submission for one member of the prime Xiaomi Mi 8 family. Mi 8 Pro (equuleus) and Mi 8 Explorer (ursa) are nearly identical. Known differences are battery capacity and fingerprint sensor placement. This submission includes basic abstraction for other developers to be able easily extend it to support other variants.
What does work: framebuffer, USB, UFS, Bluetooth, Wi-Fi. Based on work of multiple people trying to bring the device in the past. Last attempt was done by Max Furman.
