24    description:
25      Should be the frequency (in Hz) of the ciu clock.  If this
26      is specified and the ciu clock is specified then we'll try to set the ciu
27      clock to this at probe time.

32    description:
33      The maximum size of the tx/rx fifo's. If this property is not
34      specified, the default value of the fifo size is determined from the
35      controller registers.

42      Delay in milli-seconds before detecting card after card
43      insert event. The default value is 0.

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

54  fifo-watermark-aligned:
55    allOf:
56      - $ref: /schemas/types.yaml#/definitions/flag
57    description:
58      Data done irq is expected if data length is less than
59      watermark in PIO mode. But fifo watermark is requested to be aligned
60      with data length in some SoC so that TX/RX irq can be generated with
61      data done irq. Add this watermark quirk to mark this requirement and
62      force fifo watermark setting accordingly.
