1*4882a593SmuzhiyunDevice Tree bindings for MVEBU SDRAM controllers 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunThe Marvell EBU SoCs all have a SDRAM controller. The SDRAM controller 4*4882a593Smuzhiyundiffers from one SoC variant to another, but they also share a number 5*4882a593Smuzhiyunof commonalities. 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunFor now, this Device Tree binding documentation only documents the 8*4882a593SmuzhiyunArmada XP SDRAM controller. 9*4882a593Smuzhiyun 10*4882a593SmuzhiyunRequired properties: 11*4882a593Smuzhiyun 12*4882a593Smuzhiyun - compatible: for Armada XP, "marvell,armada-xp-sdram-controller" 13*4882a593Smuzhiyun - reg: a resource specifier for the register space, which should 14*4882a593Smuzhiyun include all SDRAM controller registers as per the datasheet. 15*4882a593Smuzhiyun 16*4882a593SmuzhiyunExample: 17*4882a593Smuzhiyun 18*4882a593Smuzhiyunsdramc@1400 { 19*4882a593Smuzhiyun compatible = "marvell,armada-xp-sdram-controller"; 20*4882a593Smuzhiyun reg = <0x1400 0x500>; 21*4882a593Smuzhiyun}; 22
