| * Ingenic JZ47xx MMC controllers |
| |
| This file documents the device tree properties used for the MMC controller in |
| Ingenic JZ4740/JZ4780 SoCs. These are in addition to the core MMC properties |
| described in mmc.txt. |
| |
| Required properties: |
| - compatible: Should be one of the following: |
| - "ingenic,jz4740-mmc" for the JZ4740 |
| - "ingenic,jz4725b-mmc" for the JZ4725B |
| - "ingenic,jz4780-mmc" for the JZ4780 |
| - reg: Should contain the MMC controller registers location and length. |
| - interrupts: Should contain the interrupt specifier of the MMC controller. |
| - clocks: Clock for the MMC controller. |
| |
| Optional properties: |
| - 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. |
| Should be "rx" and "tx", in that order. |
| |
| For additional details on DMA client bindings see ../dma/dma.txt. |
| |
| Example: |
| |
| mmc0: mmc@13450000 { |
| compatible = "ingenic,jz4780-mmc"; |
| reg = <0x13450000 0x1000>; |
| |
| interrupt-parent = <&intc>; |
| interrupts = <37>; |
| |
| clocks = <&cgu JZ4780_CLK_MSC0>; |
| clock-names = "mmc"; |
| |
| dmas = <&dma JZ4780_DMA_MSC0_RX 0xffffffff>, <&dma JZ4780_DMA_MSC0_TX 0xffffffff>; |
| dma-names = "rx", "tx"; |
| }; |
