    +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 channels 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 13>;
    + dma-names = "tx", "rx";
    +};
