Vinod, Do you have an immutable branch based on which I can send this patch series to ARM-SoC? Some of the patches in the series depend on code that went through your tree. Or if you are comfortable taking this series through your tree, thats okay by me too. We are still waiting for acks from DT maintainers on the binding change patches.
