Notes:
    v0 -> v1:
    Rob Herring:
    - replaced maintainers
    - defined each entry in reg, interrupts
    - dropped dma-channels
    
    Krzysztof Kozlowski:
    - fixed title
    - renamed files
    - use fallback compatible and list all possible compatibles
    - dropped label
    - fix ident
