From 5264d2749fa3a52bc3adf3937c284590cf0b3ecf Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 24 Apr 2015 11:57:06 +0200 Subject: [PATCH] ARM: tegra: Add missing HDMI +5V regulator Commit fb50a116bbbc ("drm/tegra: hdmi - Add connector supply support") introduced a new supply for HDMI connectors that is used to control the voltage on the +5V pin. Not all boards have had the corresponding supply added to their device tree files, causing the following warning message during boot: [ 0.859698] 54280000.hdmi supply hdmi not found, using dummy regulator Add such a regulator to the Seaboard DTS to enable the driver to control this voltage and get rid of the warning.
