arm/dts: omap3-beagle: Add twl4030 and i2c EEPROM
Add required clock frequencies for the i2c client devices existing on beagle board. Add the twl4030 basic description with only the twl_rtc module. Add the EEPROM node. Based on original patch from Manju: http://www.spinics.net/lists/linux-omap/msg55831.html Signed-off-by: Benoit Cousson <b-cousson@ti.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Rob Herring <rob.herring@calxeda.com>
