X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5340b51d78a245e01a890e85f4f0159593f90153;p=linux-beck.git

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:
