Broadcom BCM2835 SDHOST controller



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";

};
