0023 clock-frequency:
0024 description:
0025 Should be the frequency (in Hz) of the ciu clock. If this
0026 is specified and the ciu clock is specified then we'll try to set the ciu
0027 clock to this at probe time.

0029 fifo-depth:
0030 description:
0031 The maximum size of the tx/rx fifo's. If this property is not
0032 specified, the default value of the fifo size is determined from the
0033 controller registers.

0036 card-detect-delay:
0037 description:
0038 Delay in milli-seconds before detecting card after card
0039 insert event. The default value is 0.

0043 data-addr:
0044 description:
0045 Override fifo address with value provided by DT. The default FIFO reg
0046 offset is assumed as 0x100 (version < 0x240A) and 0x200(version >= 0x240A)
0047 by driver. If the controller does not follow this rule, please use
0048 this property to set fifo address in device tree.

0051 fifo-watermark-aligned:
0052 description:
0053 Data done irq is expected if data length is less than
0054 watermark in PIO mode. But fifo watermark is requested to be aligned
0055 with data length in some SoC so that TX/RX irq can be generated with
0056 data done irq. Add this watermark quirk to mark this requirement and
0057 force fifo watermark setting accordingly.
