From 83919ef0a5daa5eee163b060f7c682584df97917 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 4 Jul 2016 15:10:57 +0200 Subject: [PATCH] ARM: dts: Ux500: fix up TVK sensor data - Fix the I2C address and supply line names for the AK8974 - Sets up the interrupt lines to the different components as they actually are connected, I was confused for some time by the fact that several lines were connected with 0 Ohm resistors, which means NOT MOUNTED and is thus not 0 Ohm at all but infinite ohms, i.e. not connected at all.
