Marcus Folkesson	2596e9414e	dt-bindings: display: sitronix,st7571: add optional inverted property ... Depending on which display that is connected to the controller, an "1" means either a black or a white pixel. The supported formats (R1/R2/XRGB8888) expects the pixels to map against (4bit): 00 => Black 01 => Dark Gray 10 => Light Gray 11 => White If this is not what the display map against, the controller has support to invert these values.
