From 252130d8d6e082041589ff5b22708e39971303c0 Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Mon, 24 Jul 2017 19:33:11 +0200 Subject: [PATCH] ARM: dts: n950: add display support Add basic panel support for the Nokia N950. It must be tweaked a little bit later, since the panel was built into the device upside-down. Also the first 5 and the last 5 pixels are covered by plastic.
