From aee02b0fc0258c67941ddfe95fb68d80b54ad4ad Mon Sep 17 00:00:00 2001 From: David Lechner Date: Mon, 7 Aug 2017 12:39:38 -0500 Subject: [PATCH] dt-bindings: add binding for Sitronix ST7586 display panels MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This adds a new binding for Sitronix ST7586 display panels. Using lego as the vendor prefix in the compatible string because the display panel I am working with is an integral part of the LEGO MINDSTORMS EV3.
