Swap dma-coherent for > dma-noncoherent. I have favour to ask. Can you capitalise (so-called "title case") the subject when submitting patches that are PCI-specific DT bindings? This is the preferred style for PCI, at least at the moment. Also, it would save us the need to do it every time. :) Thank you! Krzysztof
