- * TI Highspeed MMC host controller for DaVinci
- The Highspeed MMC Host Controller on TI DaVinci family
- provides an interface for MMC, SD and SDIO types of memory cards.
- This file documents the properties used by the davinci_mmc driver.
- Required properties:
- - compatible:
- Should be "ti,da830-mmc": for da830, da850, dm365
- Should be "ti,dm355-mmc": for dm355, dm644x
- Optional properties:
- - bus-width: Number of data lines, can be <1>, <4>, or <8>, default <1>
- - max-frequency: Maximum operating clock frequency, default 25MHz.
- - dmas: List of DMA specifiers with the controller specific format
- as described in the generic DMA client binding. A tx and rx
- specifier is required.
- - dma-names: RX and TX DMA request names. These strings correspond
- 1:1 with the DMA specifiers listed in dmas.
- Example:
- mmc0: mmc@1c40000 {
- compatible = "ti,da830-mmc",
- reg = <0x40000 0x1000>;
- interrupts = <16>;
- status = "okay";
- bus-width = <4>;
- max-frequency = <50000000>;
- dmas = <&edma 16
- &edma 17>;
- dma-names = "rx", "tx";
- };
