From 6f684de537bcd813bcbdbc917c5b41b1fc5b7d8d Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Tue, 21 Jul 2015 16:59:28 +0200 Subject: [PATCH] drm/tegra: sor: Hook up I2C-over-AUX to output This is necessary for the output abstraction to retrieve a list of valid modes from the EDID of a connected panel/monitor. This will be useful in conjunction with DisplayPort support that will be added in a subsequent patch, so that the driver can read EDID via the AUX channel.
