From 6e376822ee9e06c5fa81424c8cf9218abfabefff Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 8 Feb 2017 16:44:00 +0100 Subject: fbdev/ssd1307fb: clear screen in probe MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SSD1306 does not clear the panel's framebuffer automatically, even if a HW reset happens, so we need to do that at probe time before enabling the panel.
