From 2596e9414e5f5917070a6c524d8e307234d3cc18 Mon Sep 17 00:00:00 2001 From: Marcus Folkesson Date: Mon, 21 Jul 2025 12:43:32 +0200 Subject: [PATCH] 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.
