It's in staging, nobody has registered any interest, the company behind the hardware as publicly said they won't continue development, and there's no documentation.

In the very unlikely case someone would want to revive it, the source code will live in git history. > >> Link: https://lore.kernel.org/all/ZQ0PR01MB13024A92926C415C187D2C18F29F2@ZQ0PR01MB1302.CHNPR01.prod.partner.outlook.cn/ > >> Acked-by: Changhuang Liang > >> Signed-off-by: Jai Luthra > > > > Reverting/dropping changes is always in reverse of introducing them, so > > this must be second commit.
