-* Wondermedia WM8505/WM8650 SD/MMC Host Controller
-
-This file documents differences between the core properties described
-by mmc.txt and the properties used by the wmt-sdmmc driver.
-
-Required properties:
-- compatible: Should be "wm,wm8505-sdhc".
-- interrupts: Two interrupts are required - regular irq and dma irq.
-
-Optional properties:
-- sdon-inverted: SD_ON bit is inverted on the controller
-
-Examples:
-
-sdhc@d800a000 {
-	compatible = "wm,wm8505-sdhc";
-	reg = <0xd800a000 0x1000>;
-	interrupts = <20 21>;
-	clocks = <&sdhc>;
-	bus-width = <4>;
-	sdon-inverted;
-};
