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. 28 29 fifo-depth: 30 description: 31 The maximum size of the tx/rx fifo's. If this property is not 32 specified, the default value of the fifo size is determined from the 33 controller registers. 34 $ref: /schemas/types.yaml#/definitions/uint32 35 36 card-detect-delay: 37 description: 38 Delay in milli-seconds before detecting card after card 39 insert event.

The default FIFO reg 46 offset is assumed as 0x100 (version < 0x240A) and 0x200(version >= 0x240A) 47 by driver. If the controller does not follow this rule, please use 48 this property to set fifo address in device tree. 49 $ref: /schemas/types.yaml#/definitions/uint32 50 51 fifo-watermark-aligned: 52 description: 53 Data done irq is expected if data length is less than 54 watermark in PIO mode. But fifo watermark is requested to be aligned 55 with data length in some SoC so that TX/RX irq can be generated with 56 data done irq. Add this watermark quirk to mark this requirement and 57 force fifo watermark setting accordingly. 58 $ref: /schemas/types.yaml#/definitions/flag 59 60 dmas: 61 maxItems: 1 62 63 dma-names: 64 const: rx-tx 65 66 additionalProperties: true
