This file documents differences between the core properties described
by mmc.txt and the properties that represent the BCM2835 controller.
Required properties:
- compatible: Should be “brcm,bcm2835-sdhost”.
- clocks: The clock feeding the SDHOST controller.
Optional properties:
- dmas: DMA channel for read and write.
See Documentation/devicetree/bindings/dma/dma.txt for details
Example:
sdhost: mmc@7e202000 {
compatible = “brcm,bcm2835-sdhost”;
reg = <0x7e202000 0x100>;
interrupts = <2 24>;
clocks = <&clocks BCM2835_CLOCK_VPU>;
dmas = <&dma 13>;
dma-names = “rx-tx”;
};
