From 3ce83ee0125fdf2908c39970335121909e98b750 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Mon, 3 Aug 2020 15:45:33 +0200 Subject: [PATCH] video: ipuv3: fix framebuffer base address init with multiple IPUs Since commit 7812bbdc3732 ("video: Correctly handle multiple framebuffers") the vidconsole output is missing on the primary display on boards with two IPU units (all i.MX6Q/D based boards). The base address of the allocated framebuffer is not correctly programmed in the display controller. Fix it.
