Broadcom BCM2835 SDHCI 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-sdhci".
- clocks : The clock feeding the SDHCI controller.
Example:
sdhci: sdhci {
compatible = "brcm,bcm2835-sdhci";
reg = <0x7e300000 0x100>;
interrupts = <2 30>;
clocks = <&clk_mmc>;
bus-width = <4>;
};
