Sigmastar MI_DISP API

The Sigmastar MI_DISP API documentation for customer development.

Overview of MI_DISP:

MI_DISP is another interesting one, where if you enable it within a binary that binary must continue to run or MI_DISP will be disabled. An example of this is also /dev/l which initialises MI_DISP and holds it open by entering a loop, the loop breaks if you send a -2 kill into /dev/l I've found mo current way to read back pushed in CSC changes so if someone finds a way please let me know! (Store a local copy of what you set is the way around this) Modifying MI_DISP values is not a permanent change and can be reset by pushing in the default or rebooting!

Hey! Some info for you!

- If you disable mi_disp by calling /dev/l you can spawn /dev/l again by calling `cat /proc/ls`

- If mi_disp is not currently running you can *NOT* push in CSC changes! (No colour changes ie: blue light filter will stop working)
