From 44d032e7940131fd991a01a948630747d91fe983 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 26 Jan 2013 20:50:12 +0000 Subject: ARM: Kirkwood: topkick: Enable i2c bus. Add a DT node for I2C and pinctrl hog for the pins. There appears to be an i2c bus on topkick with a device on it: i2cdetect 0 WARNING! This program can confuse your I2C bus, cause data loss and worse! I will probe file /dev/i2c-0. I will probe address range 0x03-0x77. Continue?
