From e6f097960621828bdce238aef7a7fc5404bfca71 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 16 Nov 2012 16:56:50 +0100 Subject: [PATCH] ARM: tegra: tamonten: Add host1x support Hook up the required regulators, I2C DDC adapter and hotplug detect GPIO to the Tamonten HDMI output. Carrier boards still need to explicitly enable the output to use it.
