    miso-pull-up:

    anomaly-58-workaround:
      type: boolean
      required: false
      description: |
        Enables the workaround for the nRF52832 SoC SPIM PAN 58 anomaly.
        Must be used in conjunction with
        CONFIG_SOC_NRF52832_ALLOW_SPIM_DESPITE_PAN_58=y

    rx-delay-supported:
      type: boolean
      required: false
      description: |
        Indicates if the SPIM instance has the capability of delaying MISO
        sampling. This property needs to be defined at SoC level DTS files.

    rx-delay:
      type: int
      required: false
      enum:
        - 0
        - 1
        - 2
        - 3
        - 4
        - 5
        - 6
        - 7
      description: |
        Number of 64 MHz clock cycles (15.625 ns) delay from the sampling edge
        of SCK (leading or trailing, depending on the CPHA setting used) until
        the input serial data on MISO is actually sampled. This property does
        not have any effect if the rx-delay-supported property is not set.
