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.

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.
