-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";
-};
