From 37d7b7a5baca43722d332e190a3c86ac0c4341e8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michal=20Vok=C3=A1=C4=8D?= Date: Fri, 31 Jul 2020 14:00:08 +0200 Subject: [PATCH] ARM: dts: imx6dl-yapp4: Add support for OLED based on different controller MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit OLED display consist of an OLED panel and a display controller. The displays that were used on yapp4 platform were based on a SSD1305 controller. These displays are now discontinued and we need to add support for a replacement. The new display is based on SSD1309 controller and requires slightly different configuration (mirror + segment offset). We want to support both display types so it does no matter which one was used on the assembly line. Hence the displays are placed at different I2C addresses.
