dtschema.

This breaks probing of Exynos event counters, which are needed by the 
Exynos DMC driver on Odroid XU3/XU4/HC1 boards. Just check the today's 
linux-next. I had no time to analyze which part of the code depends on 
the node names though...

Best regards

Thanks for the report. I'll drop the patch from my queue and check later
the driver.


Best regards,
