This file documents DT bindings for the AR0521 camera sensor driver. Changes from v1: - added power management (power supplies). - small fixes The question still stands: is there a way to reliably put national unicode characters into: - commit messages for patches submitted via email, - C and other source files (comments and stuff like MODULE_AUTHOR). Yes, I know I can commit it myself correctly, but then propagating it upstream is problematic. Perhaps a pullable tree would be better? I guess I need to renew my old kernel.org account.
