+Broadcom IPROC SDHCI controller
+
+This file documents differences between the core properties described
+by mmc.txt and the properties that represent the IPROC SDHCI controller.
+
+Required properties:
+- compatible : Should be "brcm,sdhci-iproc-cygnus".
+- clocks : The clock feeding the SDHCI controller.
+
+Optional properties:
+ - sdhci,auto-cmd12: specifies that controller should use auto CMD12.
+
+Example:
+
+sdhci0: sdhci@0x18041000 {
+ compatible = "brcm,sdhci-iproc-cygnus";
+ reg = <0x18041000 0x100>;
+ interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&lcpll0_clks BCM_CYGNUS_LCPLL0_SDIO_CLK>;
+ bus-width = <4>;
+ sdhci,auto-cmd12;
+ no-1-8-v;
+};
