properties:
resets:
maxItems: 1
reset-names:
const: reset
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:
allOf:
- $ref: /schemas/types.yaml#/definitions/uint32
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.
card-detect-delay:
allOf:
- $ref: /schemas/types.yaml#/definitions/uint32
- default: 0
description:
Delay in milli-seconds before detecting card after card
insert event. The default value is 0.
data-addr:
allOf:
- $ref: /schemas/types.yaml#/definitions/uint32
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:
allOf:
- $ref: /schemas/types.yaml#/definitions/flag
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.
