      clock-frequency:
        description:
          Should be the frequency (in Hz) of the ciu clock.  If this
          is specified and the ciu clock is specified then we'll try to set the ciu
          clock to this at probe time.
    
      fifo-depth:
        description:
          The maximum size of the tx/rx fifo's. If this property is not
          specified, the default value of the fifo size is determined from the
          controller registers.

      card-detect-delay:
        description:
          Delay in milli-seconds before detecting card after card
          insert event. The default value is 0.

        default: 0
    
      data-addr:
        description:
          Override fifo address with value provided by DT. The default FIFO reg
          offset is assumed as 0x100 (version < 0x240A) and 0x200(version >= 0x240A)
          by driver. If the controller does not follow this rule, please use
          this property to set fifo address in device tree.

      fifo-watermark-aligned:
        description:
          Data done irq is expected if data length is less than
          watermark in PIO mode. But fifo watermark is requested to be aligned
          with data length in some SoC so that TX/RX irq can be generated with
          data done irq. Add this watermark quirk to mark this requirement and
          force fifo watermark setting accordingly.
