Openblocks AX3-4 i2c bus lockup

Hi Nobuhiro

You added I2C into the Openblocks AX3-4 device tree and the subnode
for the RTC. Did you have any problems with I2C? I'm having lots of
problems with my AX3-4 and i2c. I get i2c errors and the bus being
locked and then the whole machine locks solid.

Gregory, did you test your I2C patches for 370/XP on an Openblocks
AX3-4?

Thanks
