-Device Tree bindings for MVEBU SDRAM controllers
-
-The Marvell EBU SoCs all have a SDRAM controller. The SDRAM controller
-differs from one SoC variant to another, but they also share a number
-of commonalities.
-
-For now, this Device Tree binding documentation only documents the
-Armada XP SDRAM controller.
-
-Required properties:
-
- - compatible: for Armada XP, "marvell,armada-xp-sdram-controller"
- - reg: a resource specifier for the register space, which should
-   include all SDRAM controller registers as per the datasheet.
-
-Example:
-
-sdramc@...0 {
-	compatible = "marvell,armada-xp-sdram-controller";
-	reg = <0x1400 0x500>;
-};
