1*c66ec88fSEmmanuel VadotDevice Tree bindings for MVEBU SDRAM controllers 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotThe Marvell EBU SoCs all have a SDRAM controller. The SDRAM controller 4*c66ec88fSEmmanuel Vadotdiffers from one SoC variant to another, but they also share a number 5*c66ec88fSEmmanuel Vadotof commonalities. 6*c66ec88fSEmmanuel Vadot 7*c66ec88fSEmmanuel VadotFor now, this Device Tree binding documentation only documents the 8*c66ec88fSEmmanuel VadotArmada XP SDRAM controller. 9*c66ec88fSEmmanuel Vadot 10*c66ec88fSEmmanuel VadotRequired properties: 11*c66ec88fSEmmanuel Vadot 12*c66ec88fSEmmanuel Vadot - compatible: for Armada XP, "marvell,armada-xp-sdram-controller" 13*c66ec88fSEmmanuel Vadot - reg: a resource specifier for the register space, which should 14*c66ec88fSEmmanuel Vadot include all SDRAM controller registers as per the datasheet. 15*c66ec88fSEmmanuel Vadot 16*c66ec88fSEmmanuel VadotExample: 17*c66ec88fSEmmanuel Vadot 18*c66ec88fSEmmanuel Vadotsdramc@1400 { 19*c66ec88fSEmmanuel Vadot compatible = "marvell,armada-xp-sdram-controller"; 20*c66ec88fSEmmanuel Vadot reg = <0x1400 0x500>; 21*c66ec88fSEmmanuel Vadot}; 22
