Yes, there seems to be a problem here now. The i2c adapter does not get 
probed, i.e., of-matching doesn't work. A quick look through other 
device-trees, using the same i2c driver, through git-logs of the i2c 
driver and the dts didn't bring me to a solution. Can anyone spot what's 
wrong with kuroboxHG.dts? lsprop output looks reasonable. Last working 
kernel was 2.6.25-rc6-ish.

No, kurobox uses generic RTC class.

Thanks for the report
