    pinctrl-0:
      type: phandles
      description: |
        PIO pin configuration for RF, RK, RD, TF, TK, & TD signals.
        We expect that the phandles will reference pinctrl nodes.
        These nodes will have a nodelabel that matches the Atmel SoC HAL
        defines and be of the form p<port><pin><periph>_<inst>_<signal>.

        For example the SSC on SAME7x would be
           pinctrl-0 = <&pd24b_ssc_rf &pa22a_ssc_rk &pa10c_ssc_rd
                        &pb0d_ssc_tf &pb1d_ssc_tk &pb5d_ssc_td>;

      required: true

    dmas:
      required: true
      description: |
        TX & RX dma specifiers.  Each specifier will have a phandle
        reference to the dma controller, the channel number, and peripheral
        trigger source.

        For example dmas for TX, RX would look like
           dmas = <&xdmac 22 DMA_PERID_SSC_TX>, <&xdmac 23 DMA_PERID_SSC_RX>;

    dma-names:
      required: true
      description: |
        This should be "tx" and "rx" to match the dmas property.

        For example
           dma-names = "tx", "rx";
