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. |

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

|
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. |
