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.

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

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:

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.
