Required properties:
|
|
|
|
- compatible : Must be "moxa,moxart-mmc" or "faraday,ftsdc010"
|
|
- reg : Should contain registers location and length
|
|
- interrupts : Should contain the interrupt number
|
|
- clocks : Should contain phandle for the clock feeding the MMC controller
|
|
|
|
Optional properties:
|
|
|
|
- dmas : Should contain two DMA channels, line request number must be 5 for
|
|
both channels
|
|
- dma-names : Must be "tx", "rx"
|
|

|
Example:
|
|
|
|
mmc: mmc@98e00000 {
|
|
compatible = "moxa,moxart-mmc";
|
|
reg = <0x98e00000 0x5C>;
|
|
interrupts = <5 0>;
|
|
clocks = <&clk_apb>;
|
|
dmas = <&dma 5>,
|
|
<&dma 5>;
|
|
dma-names = "tx", "rx";
