From 898ee397c31a4f057c2f3a200784d62bd64e83b0 Mon Sep 17 00:00:00 2001 From: Benoit Cousson Date: Wed, 17 Aug 2011 18:42:25 +0530 Subject: arm/dts: omap4-panda: Add twl6030 and i2c EEPROM Update pandaboard dts file with required clock frequencies for the i2c client devices existing on pandaboard. Add the twl6030 node in i2c1 controller. This is the minimal support needed to boot OMAP4 boards without any crash. The support for all the features included in this MFD will be added later. Add a generic i2c EEPROM entry.
