23  clock-frequency:
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.

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

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

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

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