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,jz4780-mmc" for the JZ4780
11- reg: Should contain the MMC controller registers location and length.
12- interrupts: Should contain the interrupt specifier of the MMC controller.
13- clocks: Clock for the MMC controller.
14
15Optional properties:
16- dmas: List of DMA specifiers with the controller specific format
17        as described in the generic DMA client binding. A tx and rx
18        specifier is required.
19- dma-names: RX and TX  DMA request names.
20        Should be "rx" and "tx", in that order.
21
22For additional details on DMA client bindings see ../dma/dma.txt.

29
30	interrupt-parent = <&intc>;
31	interrupts = <37>;
32
33	clocks = <&cgu JZ4780_CLK_MSC0>;
34	clock-names = "mmc";
35
36	dmas = <&dma JZ4780_DMA_MSC0_RX 0xffffffff>, <&dma JZ4780_DMA_MSC0_TX 0xffffffff>;
37	dma-names = "rx", "tx";
38};
