Device Tree bindings for MVEBU SDRAM controllersThe Marvell EBU SoCs all have a SDRAM controller. The SDRAM controllerdiffers from one SoC variant to another, but they also share a numberof commonalities.For now, this Device Tree binding documentation only documents theArmada 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@1400 { compatible = "marvell,armada-xp-sdram-controller"; reg = <0x1400 0x500>;};
