1* Ingenic JZ47xx MMC controllers 2 3This file documents the device tree properties used for the MMC controller in 4Ingenic JZ4740/JZ4780 SoCs. These are in addition to the core MMC properties 5described in mmc.txt. 6 7Required properties: 8- compatible: Should be one of the following: 9 - "ingenic,jz4740-mmc" for the JZ4740 10 - "ingenic,jz4725b-mmc" for the JZ4725B 11 - "ingenic,jz4780-mmc" for the JZ4780 12- reg: Should contain the MMC controller registers location and length. 13- interrupts: Should contain the interrupt specifier of the MMC controller. 14- clocks: Clock for the MMC controller. 15 16Optional properties: 17- dmas: List of DMA specifiers with the controller specific format 18 as described in the generic DMA client binding. A tx and rx 19 specifier is required. 20- dma-names: RX and TX DMA request names. 21 Should be "rx" and "tx", in that order. 22 23For additional details on DMA client bindings see ../dma/dma.txt. 24 25Example: 26 27mmc0: mmc@13450000 { 28 compatible = "ingenic,jz4780-mmc"; 29 reg = <0x13450000 0x1000>; 30 31 interrupt-parent = <&intc>; 32 interrupts = <37>; 33 34 clocks = <&cgu JZ4780_CLK_MSC0>; 35 clock-names = "mmc"; 36 37 dmas = <&dma JZ4780_DMA_MSC0_RX 0xffffffff>, <&dma JZ4780_DMA_MSC0_TX 0xffffffff>; 38 dma-names = "rx", "tx"; 39}; 40
