    3 Required properties:
    4 - compatible : should be "nvidia,tegra20-slink", "nvidia,tegra30-slink".
    5 - reg: Should contain SLINK registers location and length.
    6 - interrupts: Should contain SLINK interrupts.
    7 - clocks : Must contain one entry, for the module clock.
    8   See ../clocks/clock-bindings.txt for details.
    9 - resets : Must contain an entry for each entry in reset-names.
   10   See ../reset/reset.txt for details.
   11 - reset-names : Must include the following entries:
   12   - spi
   13 - dmas : Must contain an entry for each entry in clock-names.
   14   See ../dma/dma.txt for details.
   15 - dma-names : Must include the following entries:
   16   - rx
   17   - tx
   18
