From 802a849948789b6059899d79a4c8e71db19a6029 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Thu, 26 Apr 2012 11:21:54 -0600 Subject: [PATCH] ARM: dt: tegra seaboard: configure I2C2 pinmux The I2C2 controller can be routed to either pingroup DDC or PTA. Seaboard actually uses this as an I2C bus mux, and devices are connected to both pingroups. This change statically assigns the I2C2 controller to pingroup PTA, so that on-board devices can be accessed. The DDC pingroup is used for EDID/DDC accesses which are not yet required, given the absence of any Tegra graphics support. I2C muxing will be supported later.
